The lead generation industry runs on its own vocabulary. If you're new to buying and working leads, you'll hear terms thrown around in vendor calls, CRM dashboards, and team meetings that nobody bothers to explain. If you've been in the business for years, you probably use dozens of these terms daily without thinking about them — but your new hires don't know what half of them mean.
This glossary is your reference. Every term is defined in plain language, the way I'd explain it to a sales professional sitting across from me. No academic definitions. No marketing theory. Just what you need to know to do your job.

A/B Testing
A/B testing is running two versions of something — a landing page, an email subject line, a call script — against each other to see which one performs better. You split your audience randomly: half see version A, half see version B. The version with better results (higher open rate, more conversions, more appointments) wins. Also called split testing. The key is to only change one variable at a time, or you won't know what actually made the difference.
Aged Lead
An aged lead is a lead that was generated days, weeks, or months ago and was either never contacted or was contacted but didn't convert. These leads are resold at a steep discount compared to fresh leads — often 80-95% less. The trade-off is lower contact rates, but the math works because the cost per acquisition can be dramatically lower. Many successful sales operations are built entirely on aged leads purchased from providers like AgedLeadStore.
Appointment Setting
Appointment setting is the process of contacting leads and scheduling them for a sales conversation — either a phone call, video meeting, or in-person appointment. In many sales organizations, appointment setters are separate from closers. The setter's job is to qualify interest and book the meeting. The closer's job is to convert the appointment into a sale. This division of labor lets your best closers spend their time on qualified prospects instead of dialing through raw lists.
A2P Messaging
A2P stands for application-to-person messaging. It's any text message sent from a software platform to a person's phone, as opposed to person-to-person (P2P) texting between two individuals. Every automated text you send through a CRM, dialer, or marketing platform is classified as A2P. Since 2024, all A2P messages on 10-digit long codes require 10DLC registration with carriers. If you're texting leads from any platform, you're sending A2P messages, and you need to be registered.
Autodialer
An autodialer is any system that automatically dials phone numbers from a list without requiring a human to manually punch in each number. The term covers everything from simple click-to-dial tools to sophisticated predictive dialers. Under the TCPA, using an autodialer to call cell phones without prior express consent carries significant legal risk. Know the rules before you turn one on.
B2B Lead
A B2B (business-to-business) lead is a prospect representing a company that might buy your product or service for business use. B2B leads typically have longer sales cycles, higher deal values, and involve multiple decision-makers. The lead generation approach is different from B2C — you're targeting job titles, company sizes, and business needs rather than individual consumer behavior.
B2C Lead
A B2C (business-to-consumer) lead is an individual consumer who has expressed interest in a product or service for personal use. Insurance leads, mortgage leads, solar leads — these are all B2C. The sales cycle is usually shorter than B2B, but volume is higher and you're often competing with multiple vendors who received the same lead. Speed and persistence matter more in B2C.
Bounce Rate
Bounce rate has two meanings depending on context. For websites, it's the percentage of visitors who land on a page and leave without taking any action. For email, it's the percentage of emails that fail to deliver — either because the address doesn't exist (hard bounce) or the inbox is full (soft bounce). In lead generation, a high email bounce rate on your lead list means your data quality is poor. If more than 5% of your emails bounce, your list needs cleaning.
Buyer Intent
Buyer intent is any signal that suggests a prospect is actively considering a purchase. Filling out a quote request form is high intent. Downloading a general informational PDF is low intent. In lead generation, leads are often scored or priced based on intent level. A lead who typed "best term life insurance quotes" into Google and filled out a form has stronger buyer intent than someone who clicked a Facebook ad out of curiosity.
Brand Registration (10DLC)
Brand registration is the first step in the 10DLC compliance process for sending business text messages. You register your company's legal information — business name, EIN, address, website — with The Campaign Registry (TCR). Carriers use this information to assign your brand a trust score, which determines how many messages you can send per second and how aggressively your messages are filtered. Higher trust scores mean better deliverability. This is a one-time setup, but it's mandatory before you can register any SMS campaigns.
Call Disposition
A call disposition is the outcome code you assign to a call after it ends. Common dispositions include: no answer, voicemail left, callback requested, not interested, appointment set, wrong number, and disconnected. Dispositions are how you track what's actually happening in your dial sessions. If your CRM doesn't have clear disposition options, your reporting is blind. Good dispositions drive good follow-up — a "callback requested" lead should trigger a different cadence than a "no answer."
Campaign Registration
Campaign registration is the second step in 10DLC compliance, after brand registration. You register each specific use case for your SMS messaging — lead follow-up, appointment reminders, promotional offers — with sample messages, opt-in descriptions, and expected volume. Carriers review your campaign and approve or reject it. Your actual messages must match what you described in the registration. Sending messages that don't align with your approved campaign type can get your messaging suspended.
Click-Through Rate (CTR)
Click-through rate is the percentage of people who click a link after seeing it. For email, it's clicks divided by emails delivered. For ads, it's clicks divided by impressions. A 2% CTR on email is considered decent for sales outreach. A 5% CTR on a Google ad is strong. CTR tells you whether your message is compelling enough to earn the next step — but it doesn't tell you whether those clicks convert into anything useful. Always pair CTR with conversion data.
Close Rate
Close rate is the percentage of leads or opportunities that result in a completed sale. If you work 100 leads and close 5 deals, your close rate is 5%. This is the metric that ties everything together — your lead quality, your sales process, your follow-up cadence, and your skill level all show up in your close rate. Industry benchmarks vary wildly. Fresh exclusive mortgage leads might close at 8-12%. Aged shared insurance leads might close at 1-3%. Know your number.
Cold Call
A cold call is an outbound phone call to someone who hasn't recently expressed interest in your product or service. The term is relative — calling a 90-day-old internet lead is technically warmer than calling someone from a purchased phone list, but it still feels cold to the prospect because they don't remember you. Cold calling remains one of the most effective ways to work aged leads, especially when combined with a multi-channel approach that includes texting and email.
Comparison Shopping Consent
Comparison shopping consent is a type of opt-in where a consumer agrees to be contacted by multiple companies when they submit a lead form. This is standard in lead generation — when someone fills out a "compare quotes" form, they're consenting to hear from several vendors. The FCC's one-to-one consent rule (effective January 2025) changed this landscape significantly, requiring consumers to select specific companies rather than giving blanket consent to any partner in a network.
Contact Rate
Contact rate is the percentage of leads you actually reach — meaning a live human conversation, not just a dial attempt. If you dial 100 leads and have conversations with 12, your contact rate is 12%. This is arguably the most important operational metric in lead working. Everything downstream — appointments, conversions, revenue — depends on first making contact. Fresh leads might have 25-40% contact rates. Aged leads typically run 8-15%. Your speed to lead is the single biggest lever for improving contact rate.
Conversion Rate
Conversion rate is the percentage of leads that complete a desired action — submitting an application, booking an appointment, making a purchase. The "desired action" varies by context and stage. A landing page conversion rate measures form fills. A sales conversion rate measures closed deals. When someone quotes a conversion rate without specifying what's being converted, ask. The number is meaningless without context.
Cost Per Acquisition (CPA)
CPA is the total cost to acquire one paying customer. It includes your lead cost, your labor cost (time spent dialing, following up, closing), your technology costs (CRM, dialer, phone system), and any other overhead. Most sales professionals only track lead cost, which gives an incomplete picture. If you buy leads at $5 each but spend 3 hours per conversion, your true CPA is much higher than $5. Track the full number.
Cost Per Lead (CPL)
Cost per lead is what you pay for each lead, whether you generate it yourself or buy it from a vendor. Fresh exclusive leads might cost $20-80+ depending on the vertical. Aged leads from providers like AgedLeadStore might cost $0.50-5.00. CPL is easy to track but misleading on its own — a $2 lead that never converts is infinitely more expensive than a $50 lead that closes. Always measure CPL alongside conversion rate and revenue per lead.
CRM (Customer Relationship Management)
A CRM is the software system where you manage all your lead data, communication history, follow-up tasks, and pipeline tracking. For lead workers, the CRM is the command center. Every call, text, email, and status change should be logged in the CRM. Without one, you're guessing which leads to call, when to follow up, and where your deals stand. Popular CRMs for lead-based sales include GoHighLevel, Salesforce, HubSpot, and Close.
Data Append
Data appending is the process of adding missing information to your lead records — phone numbers, email addresses, mailing addresses, demographic data — using third-party data sources. If you buy aged leads that only have name and phone number, you might append email addresses to enable multi-channel outreach. Data append services match your records against large consumer databases and fill in the gaps. Quality varies by vendor.
Dialer
A dialer is any software or hardware system used to make outbound phone calls. The term is broad and covers everything from basic click-to-dial browser extensions to full predictive dialing platforms. If you're working leads at any volume, you need a dialer. Manual dialing — looking up a number, punching it in, waiting for it to ring — wastes 70% of a sales rep's time. See also: power dialer, predictive dialer, autodialer.
DNC (Do Not Call)
The Do Not Call registry is a federal list of phone numbers belonging to consumers who have requested not to receive telemarketing calls. Before calling any lead list, you must scrub it against the national DNC registry and any applicable state DNC lists. Calling a DNC-registered number can result in fines of $500-$51,744 per violation. The exception: if a consumer has an established business relationship with you or has given prior express written consent, you can call them regardless of DNC status.
Drip Campaign
A drip campaign is an automated sequence of messages — usually emails, but increasingly texts — sent to leads over a period of time on a predetermined schedule. Instead of sending one email and hoping for a response, a drip campaign might send 7 emails over 21 days, each with a different angle or value proposition. The "drip" metaphor refers to steady, consistent contact rather than one big blast. Drip campaigns are essential for nurturing leads who aren't ready to buy immediately.
Duplicate Lead
A duplicate lead is a lead record that appears more than once in your system, usually because the same person submitted forms on multiple sites or because you purchased the same lead from different vendors. Duplicates waste time and money — you're paying twice for the same prospect and potentially calling them from two different reps. Good CRM hygiene includes deduplication rules that match on phone number, email, or a combination of fields.
Email Sequence
An email sequence is a series of pre-written emails delivered automatically based on triggers or time delays. Unlike a one-off email blast, sequences are designed to guide a prospect through a conversation over days or weeks. A typical lead follow-up sequence might include: an introduction email (day 1), a value-add email (day 3), a social proof email (day 5), and a breakup email (day 10). The best sequences feel like a real person wrote them, not a marketing department.
Exclusive Lead
An exclusive lead is sold to only one buyer. You're the only person who gets that lead's contact information. Exclusive leads cost significantly more than shared leads — often 3-5x — but your contact rates and conversion rates are dramatically higher because you're not racing against four other sales reps calling the same person. For high-value verticals like mortgage or solar, exclusive leads often deliver the best ROI despite the higher price. AgedLeadStore offers both exclusive and shared aged leads across multiple verticals.
Exit Intent
Exit intent is a technology that detects when a website visitor is about to leave a page — usually by tracking mouse movement toward the browser's close button — and triggers a popup or overlay. In lead generation, exit intent popups often offer a last-chance incentive: a discount, a free resource, or a simplified form. When done well, exit intent captures 5-10% of visitors who would have otherwise left without converting.
Follow-Up Cadence
A follow-up cadence is the structured schedule of contact attempts you make after receiving a lead. A cadence defines when you call, text, and email — and how many times — before moving a lead to a long-term nurture sequence or closing it out. Most sales professionals don't follow up enough. Research consistently shows that 80% of conversions happen between the 5th and 12th contact attempt, but the average sales rep gives up after 2. Your cadence is your discipline.
Fresh Lead
A fresh lead is a lead that was just generated — typically within the last 0-48 hours. The prospect recently filled out a form, requested a quote, or clicked an ad. Fresh leads have the highest contact rates and conversion rates because the prospect's intent is still active. They also cost the most. The critical variable with fresh leads is speed — if you don't contact them within 5 minutes of generation, your odds of conversion drop by 80%.
Funnel
A funnel is a visual model of the stages a prospect moves through from initial awareness to closed deal. The "funnel" metaphor exists because you start with a large number of people at the top (awareness) and lose some at every stage — interest, consideration, decision — until a smaller number comes out the bottom as customers. In lead generation, your funnel might look like: leads purchased > leads contacted > appointments set > applications submitted > deals closed. Every stage has a conversion rate, and improving any one of them multiplies your results.
Gated Content
Gated content is any resource — a PDF guide, a calculator, a webinar recording, a checklist — that requires a visitor to submit their contact information before they can access it. The "gate" is the form. Gated content is one of the primary mechanisms for generating inbound leads. The quality of the lead depends on the perceived value of the content: a generic "Top 10 Tips" PDF generates lower-quality leads than a detailed industry report or a custom calculator.
GoHighLevel (GHL)
GoHighLevel is an all-in-one sales and marketing platform popular with agencies and lead-based sales teams. It combines CRM, email marketing, SMS automation, landing page builder, appointment scheduling, and pipeline management into a single tool. For lead workers, GHL is attractive because it consolidates the tech stack — you can import leads, build follow-up automations, dial from within the platform, and track results without juggling five separate tools.
Hot Transfer
A hot transfer (also called a live transfer) is when a call center agent qualifies a prospect on the phone and then transfers the live call directly to a sales rep or closer. The prospect is already on the line, already interested, and has already answered qualifying questions. Hot transfers are the highest-intent lead type you can buy — and the most expensive. Conversion rates on quality hot transfers can exceed 20-30% because you're skipping the entire contact and qualification process.
Hybrid Lead Strategy
A hybrid lead strategy combines multiple lead sources — typically fresh leads, aged leads, and self-generated leads — to balance cost, volume, and quality. Instead of relying entirely on expensive fresh leads or entirely on high-volume aged leads, a hybrid approach uses fresh leads for immediate pipeline and aged leads for volume and long-term nurturing. Most mature sales operations end up running some version of a hybrid strategy because no single lead source optimizes for cost, quality, and volume simultaneously.
Inbound Lead
An inbound lead is a prospect who initiates contact with your business — they find your website, fill out a form, call your phone number, or respond to your content. Inbound leads are generally higher quality than outbound leads because the prospect has demonstrated active interest. The downside: inbound leads are hard to scale and expensive to generate (through SEO, paid ads, content marketing, or referral networks). Most sales organizations need both inbound and outbound strategies.
Internet Lead
An internet lead is any lead generated online — through search engines, social media ads, comparison shopping websites, landing pages, or any other digital channel. The term distinguishes digital leads from traditional lead sources like direct mail, television, or radio. In practice, the vast majority of purchased leads today are internet leads. When a vendor says "internet leads," they usually mean a consumer filled out a web form in response to a paid ad or organic search result.
IVR (Interactive Voice Response)
IVR is the automated phone system that greets callers with recorded menus — "Press 1 for sales, press 2 for support." In lead generation, IVR systems are used to pre-qualify inbound calls before routing them to a sales rep. A mortgage company's IVR might ask about loan type, credit score range, and property state before connecting the caller to the right agent. Well-designed IVR improves lead routing. Badly designed IVR drives prospects to hang up.
Key Performance Indicator (KPI)
A KPI is a metric you track to measure the effectiveness of your sales or marketing activity. In lead working, common KPIs include: contact rate, appointment rate, close rate, cost per acquisition, and revenue per lead. The important thing is to track the right KPIs — vanity metrics like total dials or emails sent don't tell you if you're actually generating revenue. Focus on the metrics that connect activity to outcomes.
Landing Page
A landing page is a standalone web page designed for a single purpose — usually capturing a lead. Unlike a homepage with multiple navigation options, a landing page has one call to action: fill out this form, call this number, or click this button. Good landing pages are focused, fast-loading, and mobile-optimized. In lead generation, the landing page is where the lead is born. Everything about it — the headline, the form length, the trust signals — affects your cost per lead and lead quality.
Lead
A lead is contact information for a person who has expressed some level of interest in a product or service. At minimum, a lead includes a name and phone number or email address. At best, it includes detailed qualifying information — income, credit score, location, specific needs — that helps you tailor your approach. The word "lead" gets used loosely. Be specific about what kind of lead you're discussing: fresh or aged, exclusive or shared, inbound or outbound.
Lead Age
Lead age is the time elapsed since a lead was originally generated. A lead generated today is 0 days old. A lead generated 60 days ago has a lead age of 60 days. Lead age is the primary factor in pricing — the older the lead, the cheaper it is. Lead age also correlates with contact rates and conversion rates, though not as linearly as most people assume. A well-worked 30-day-old lead can outperform a poorly worked 1-day-old lead.
Lead Distribution
Lead distribution is the process of assigning incoming leads to sales reps. Distribution can be manual (a manager assigns leads by hand), round-robin (leads are distributed equally in rotation), rules-based (leads are routed based on geography, product type, or rep expertise), or weighted (top performers get more leads). Your distribution method directly affects conversion rates — giving the right leads to the right reps at the right time is one of the highest-leverage decisions in sales management.
Lead Generation
Lead generation is the process of attracting and capturing contact information from potential customers. It encompasses everything from running Google Ads and building landing pages to buying lists and attending trade shows. The lead generation industry is massive — billions of dollars flow through it annually across insurance, mortgage, solar, home services, and dozens of other verticals. If you're reading this glossary, you're somewhere in that ecosystem.
Lead Lifecycle
The lead lifecycle is the complete journey a lead takes from the moment it's generated to its final outcome — conversion, disqualification, or archive. A typical lifecycle includes stages like: new, contacted, qualified, appointment set, proposal sent, closed-won, or closed-lost. Understanding and mapping your lead lifecycle lets you identify where leads get stuck and where you're losing the most potential revenue.
Lead Magnet
A lead magnet is a free resource offered in exchange for a prospect's contact information. Common lead magnets include PDF guides, checklists, calculators, webinars, and templates. The lead magnet's job is to attract the right audience and give them enough value that submitting their email feels like a fair trade. The best lead magnets solve a specific, immediate problem for a narrowly defined audience.
Lead Management
Lead management is the complete system of processes and tools you use to capture, distribute, track, and follow up with leads. It covers everything from how leads enter your CRM to how they're assigned to reps, how follow-up is structured, how statuses are updated, and how performance is measured. Poor lead management is the number one reason sales teams waste money on leads. You can buy the best leads in the world — if your management system is broken, they'll die in your CRM.
Lead Nurturing
Lead nurturing is the process of maintaining contact with leads who aren't ready to buy right now. Instead of marking them "not interested" and moving on, you keep them in a communication cadence — sending periodic emails, texts, or content — until they're ready to re-engage. Nurturing works because buying timelines are unpredictable. The prospect who said "not right now" in March might be ready in June. If you've been nurturing them, you're the first call they make.
Lead Qualification
Lead qualification is the process of determining whether a lead is worth pursuing based on predefined criteria — budget, authority, need, and timeline (the classic BANT framework). Not every lead is qualified. Someone who fills out a form but has a 480 credit score isn't a qualified mortgage lead. Qualification can happen at the point of generation (form questions), through automated scoring, or during the first phone call. Qualifying early saves your closers from wasting time on leads that will never convert.
Lead Routing
Lead routing is the automated process of directing incoming leads to the appropriate sales rep, team, or queue based on predefined rules. Routing rules might be based on geography (Florida leads go to the Florida team), product type (HELOC leads go to the HELOC specialist), lead score (high-score leads go to top closers), or simply round-robin distribution. The goal is matching leads with the reps best positioned to convert them, as fast as possible.
Lead Score
A lead score is a numerical value assigned to a lead based on factors that predict conversion likelihood — demographic fit, behavioral signals, engagement history, and data quality. A lead who matches your ideal customer profile, opened your last three emails, and visited your pricing page might score 85 out of 100. A lead with a disconnected phone number and no email engagement might score 12. Lead scoring helps your team prioritize who to call first.
Lead Source
Lead source identifies where a lead came from — Google Ads, Facebook, a comparison shopping site, a referral, a trade show, or a lead vendor. Tracking lead source is non-negotiable because it's the only way to know which channels actually produce revenue. Your $30 Google leads might close at 8% while your $5 aged leads close at 2%. Without lead source tracking, you can't do that math. Every lead in your CRM should have a source attached to it.
Lead Status
Lead status is the current disposition of a lead in your pipeline — new, contacted, qualified, appointment set, proposal sent, closed-won, closed-lost, or any custom status your team defines. Status tracking is how you know where every lead stands and what action needs to happen next. If your statuses are unclear or inconsistently applied, your pipeline data is unreliable, and your forecasting is guesswork.
Local Presence Dialing
Local presence dialing is a feature that displays a local area code on the prospect's caller ID, regardless of where your rep is actually calling from. If you're calling a lead in Phoenix, the caller ID shows a 602 or 480 number — even if your rep is in New Jersey. Local presence increases answer rates by 30-50% because people are more likely to pick up a call from a local number than a toll-free or out-of-state number. Most modern dialer platforms offer this feature.
Marketing Qualified Lead (MQL)
An MQL is a lead that the marketing team has determined meets a baseline threshold of interest and fit, but hasn't been vetted by sales yet. The criteria for MQL status vary by organization — it might mean the lead downloaded a specific resource, visited the pricing page, or matches certain demographic criteria. MQLs are passed to the sales team for further qualification. If your sales team complains that "marketing's leads are garbage," the MQL criteria are probably too loose.
Multi-Channel Outreach
Multi-channel outreach means contacting leads through more than one communication channel — phone, text, email, voicemail drops, direct mail, or social media. The logic is simple: not everyone answers their phone, not everyone reads email, and not everyone responds to text. By hitting leads through multiple channels, you dramatically increase your odds of making contact. The best follow-up cadences combine at least three channels in a coordinated sequence.
Nurture Sequence
A nurture sequence is a long-term automated series of communications designed to maintain a relationship with leads who aren't ready to buy. Unlike a short-term drip campaign (which might run 7-14 days), a nurture sequence can run for months — sending weekly or bi-weekly touchpoints that provide value, build trust, and keep your brand top-of-mind. When the prospect is eventually ready to buy, you want to be the name they remember.
Opt-In
An opt-in is a consumer's explicit agreement to receive communications from a business. In lead generation, the opt-in happens when someone fills out a form, checks a consent box, or takes an affirmative action indicating they want to be contacted. The specificity of the opt-in matters enormously — a generic "I agree to be contacted by partners" is weaker (legally and practically) than "I want Company X to call me about life insurance." The FCC's one-to-one consent rule now requires the latter for many lead types.
Opt-Out
An opt-out is a consumer's request to stop receiving communications. For texting, it's usually triggered by replying STOP. For email, it's the unsubscribe link. For phone, it's asking to be placed on your internal DNC list. Processing opt-outs is not optional — it's a legal requirement under the TCPA, CAN-SPAM, and various state laws. Your systems must honor opt-outs immediately and automatically. Calling someone who has opted out is one of the fastest ways to generate a complaint.
Outbound Lead
An outbound lead is a prospect you initiate contact with, rather than one who came to you. Outbound leads are generated through cold calling, cold emailing, purchased lists, or direct mail. The contact rate and conversion rate on outbound leads are typically lower than inbound, but outbound gives you control over volume and targeting. You can scale outbound effort up or down instantly, which isn't true of inbound strategies that depend on SEO or content marketing.
Pipeline
A pipeline is a visual representation of all your active deals organized by stage — from initial contact through proposal to close. Your pipeline shows you how much potential revenue is in play, where deals are stuck, and what your projected close rate looks like for the month or quarter. A healthy pipeline has deals moving steadily from left to right. If everything clusters in the early stages and nothing progresses, your qualification or follow-up process needs work.
Power Dialer
A power dialer dials one number at a time and automatically moves to the next number when a call ends (or after a set ring time). Unlike a predictive dialer, a power dialer doesn't dial multiple numbers simultaneously — it just eliminates the manual effort of looking up and dialing each number. Power dialers are the most common dialer type for small to mid-size sales teams because they're simple, compliant, and don't require a large team to avoid abandoned calls.
Predictive Dialer
A predictive dialer uses algorithms to dial multiple numbers simultaneously, predicting when a rep will become available based on average call duration and connect rates. When a live person answers, the call is routed to the next available rep. Predictive dialers maximize talk time — reps are almost always on a live call. The downside: if no rep is available when someone answers, the call is abandoned, which can violate TCPA regulations. Predictive dialers require larger teams (usually 8+ reps) to work properly.
Prior Express Written Consent (PEWC)
Prior express written consent is the highest level of consent under the TCPA. It requires a written agreement (including electronic signatures) from the consumer that specifically authorizes a particular company to contact them using automated technology or prerecorded messages. PEWC is required for all telemarketing calls to cell phones made with an autodialer or prerecorded voice. If you're buying leads and calling with a dialer, PEWC is the consent standard you need to meet. The FCC's 2025 one-to-one consent rule made this even more specific.
Prospect
A prospect is a lead that has been qualified and shows potential to become a customer. The distinction between a "lead" and a "prospect" is qualification — a lead is anyone who has expressed interest, while a prospect has been vetted against your criteria and determined to be a genuine potential buyer. In practice, many sales teams use the terms interchangeably. The important thing isn't the terminology — it's that you have a process for separating qualified opportunities from unqualified names.
Qualified Lead
A qualified lead is a lead that meets specific criteria indicating they're a genuine potential customer — they have the need, budget, authority, and timeline to make a purchase decision. The criteria vary by industry and company. A qualified mortgage lead might need a minimum credit score and verifiable income. A qualified insurance lead might need to be within a certain age range and geography. Qualification criteria should be documented, agreed upon by sales and marketing, and consistently applied.
Response Time
Response time is how quickly you contact a lead after it's generated or after the lead takes an action (submits a form, replies to a text, opens an email). In lead generation, response time is everything. Leads contacted within 5 minutes of generation are 21x more likely to convert than leads contacted after 30 minutes. This stat has been replicated in study after study across industries. If you remember one number from this entire glossary, make it this one.
Retargeting
Retargeting (also called remarketing) is serving ads to people who have previously visited your website or interacted with your content but didn't convert. When someone visits your landing page, leaves without filling out the form, and then sees your ad on Facebook or Google the next day — that's retargeting. In lead generation, retargeting captures the 95%+ of website visitors who don't convert on their first visit. It's one of the highest-ROI ad strategies because you're targeting warm audiences.
Return Policy (Leads)
A lead return policy is a vendor's terms for returning or replacing leads that don't meet agreed-upon quality standards — wrong phone numbers, disconnected numbers, leads outside your geographic area, or leads that don't match the demographic criteria you purchased. Good vendors have clear return policies with reasonable windows (24-72 hours). Always understand the return policy before buying leads, and document every return. Vendors who won't accept returns are usually selling data they know is dirty.
Revenue Per Lead
Revenue per lead (RPL) is the total revenue generated divided by the number of leads worked. If you buy 1,000 leads and generate $50,000 in revenue, your RPL is $50. This is the metric that connects your lead investment to actual business results. RPL accounts for lead cost, conversion rate, and deal size in a single number. When comparing lead sources, RPL is more useful than close rate or CPL alone because it captures the full picture.
Round Robin
Round robin is a lead distribution method where leads are assigned to sales reps in sequential, equal rotation. Rep A gets lead 1, Rep B gets lead 2, Rep C gets lead 3, then back to Rep A for lead 4. Round robin is simple, fair, and prevents cherry-picking. The limitation is that it doesn't account for rep performance, availability, or specialization. Weighted round robin — where top performers get a larger share — addresses some of these limitations.
Sales Qualified Lead (SQL)
An SQL is a lead that the sales team has vetted and confirmed as a genuine opportunity worth pursuing. The distinction from MQL: marketing said this lead looks good based on data and behavior. Sales has now had an actual conversation and confirmed the prospect has real intent, budget, and timeline. SQLs have passed both the marketing filter and the sales filter. They're your highest-probability opportunities and should receive your most focused attention.
Shared Lead
A shared lead is sold to multiple buyers — typically 3-5 companies receive the same lead's contact information simultaneously. Shared leads are cheaper than exclusive leads but come with intense competition. When a consumer fills out a comparison form and their information goes to four insurance companies, each company receives a shared lead. Success with shared leads depends almost entirely on speed and persistence. The first company to make contact wins the majority of shared lead conversions.
Speed to Lead
Speed to lead is the time between when a lead is generated and when you make first contact. It's the single most impactful metric in lead conversion. Data from multiple studies shows that leads contacted within 1 minute convert at 391% higher rates than leads contacted after 1 hour. Yet the average B2C response time is still over 40 minutes. If you do nothing else after reading this glossary, shorten your speed to lead.
Split Testing
Split testing is another term for A/B testing — running two or more variations of a marketing element against each other to determine which performs better. The term is slightly broader than A/B testing because it can include multivariate testing (testing multiple variables simultaneously). In lead generation, common split tests include landing page headlines, form length, CTA button text, email subject lines, and call scripts.
TCPA (Telephone Consumer Protection Act)
The TCPA is the federal law governing telemarketing calls, text messages, and fax communications. For lead workers, the TCPA is the single most important regulation to understand. Key provisions: you need prior express written consent to use an autodialer or prerecorded messages on cell phones for marketing purposes. You must honor DNC requests. You can't call before 8 AM or after 9 PM local time. Violations carry penalties of $500-$1,500 per call. TCPA litigation is a multi-billion dollar industry. Take it seriously.
10DLC
10DLC stands for 10-digit long code — a standard local phone number (like 555-867-5309) used for application-to-person (A2P) text messaging. Since 2024, all business texting through 10-digit numbers requires registration with carriers via The Campaign Registry. Unregistered messages are filtered or blocked entirely. The registration process involves two steps: brand registration (who you are) and campaign registration (what you're sending). If you're texting leads, 10DLC registration is not optional.
Trigger Lead
A trigger lead is a lead generated when a consumer's credit is pulled — typically during a mortgage application — and that credit inquiry triggers the sale of the consumer's information to competing lenders. The consumer didn't opt in to be contacted by these competitors. Trigger leads have been controversial for years and are now facing regulatory action, including proposed bans. If you buy mortgage leads, understand whether any of your leads are trigger-sourced, because the regulatory and reputational risks are significant.
Trust Center
A trust center is a section of a lead generation company's website (or a dedicated page) that documents their data handling practices, consent collection methods, compliance certifications, and privacy policies. Legitimate lead vendors maintain trust centers to demonstrate transparency and give buyers confidence that their leads are sourced compliantly. Before buying leads from any vendor, check their trust center — or ask why they don't have one.
Voicemail Drop
A voicemail drop (also called ringless voicemail) is a technology that delivers a pre-recorded voicemail directly to a prospect's voicemail box without ringing their phone. The message appears as a missed call with a voicemail. Voicemail drops are used in high-volume outreach to leave consistent, professional messages without tying up a rep on hold. The legal status of ringless voicemail under the TCPA is evolving — some courts have ruled it's subject to TCPA restrictions, so consult compliance counsel before deploying at scale.
Warm Lead
A warm lead is a prospect who has had some prior interaction with your business — they opened an email, responded to a text, visited your website, or were referred by someone they trust. Warm leads are between cold leads (no prior relationship) and hot leads (actively ready to buy). The warmth comes from familiarity and engagement, not just intent. Converting warm leads is primarily about timing and persistence — maintaining contact until the prospect's situation aligns with your solution.
Web Lead
A web lead is a lead generated through a website — typically when a visitor fills out a form on a landing page. The term is essentially synonymous with internet lead but specifically emphasizes the website as the capture point. Web lead quality depends on the traffic source (organic search, paid ads, social media), the landing page design, and the form's qualifying questions. More form fields generally mean fewer but higher-quality leads. Fewer fields mean more volume but more unqualified submissions.
