- Terms are organized alphabetically for quick reference.
- Updated regularly as the lead distribution industry evolves.
A
Acceptance Rate
The percentage of leads a buyer accepts out of the total delivered. A high acceptance rate (85%+) indicates good lead-to-buyer matching. Low acceptance rates signal poor targeting, bad data quality, or misaligned buyer expectations. Tracked per buyer, per source, and per campaign in platforms like Lead Distro AI.
Aged Leads
Leads that were generated days, weeks, or months ago and were not sold or contacted in real time. Aged leads are typically sold at steep discounts (50-90% off real-time pricing) because conversion rates decline sharply after the first 24 hours. Some agencies maintain aged lead inventories as a secondary revenue stream.
AI Lead Scoring
The use of artificial intelligence to evaluate lead quality by analyzing all submitted fields and assigning a numerical score in real time. Unlike rule-based scoring, AI scoring adapts to patterns across thousands of leads and evaluates holistic quality rather than checking individual field thresholds. Lead Distro AI uses Anthropic's Claude to score every inbound lead in under one second. See our AI lead scoring guide for a deep dive.
Automated Lead Distribution
The process of routing incoming leads to buyers or sales reps using software rules instead of manual assignment. Rules can include geography, lead type, buyer capacity, quality score, and bid price. Automated distribution reduces response time from hours to under one second, which is critical because companies that respond within five minutes are 100x more likely to connect (Harvard Business Review, 2011).
B
Bid Floor
The minimum price a seller will accept for a lead in a ping-post auction. If no buyer bids above the floor, the lead either goes unsold or falls through to a waterfall backup. Setting bid floors too high reduces fill rate; setting them too low leaves revenue on the table.
Buyer Cap
A daily, weekly, or monthly limit on the number of leads a buyer receives. Caps prevent oversaturation and let buyers control spend. Most lead distribution platforms allow buyers to self-manage caps through a buyer portal.
Buyer Portal
A self-service interface where lead buyers review deliveries, adjust caps, dispute leads, and track spend. A strong buyer portal reduces support load for the selling agency and increases buyer retention. Lead Distro AI includes a white-label buyer portal on all plans.
C
Cherry Pick
A distribution method where buyers manually select leads from a queue rather than receiving automatic delivery. Used in some real estate and insurance operations where buyers prefer to review leads before purchasing. Less efficient than automated routing but gives buyers maximum control.
Consent Verification
The process of confirming that a lead gave proper consent to be contacted before selling or delivering that lead. Required under TCPA and FCC regulations. Common tools include TrustedForm certificates and Jornaya LeadiD tokens. See TCPA compliance for lead generation.
Conversion Rate
The percentage of delivered leads that result in a desired outcome (sale, signed case, appointment, policy). Industry averages range from 2-15% depending on vertical, lead quality, and speed of contact. AI-scored leads convert at 2.3x the rate of non-scored leads according to Forrester research.
Cost Per Lead (CPL)
The total acquisition cost to generate one lead, including ad spend, landing page costs, and technology fees. Average CPL varies dramatically by vertical: $15-$75 for home services, $200-$600 for legal/PI, $35-$100 for insurance (FirstPageSage, 2024). Use the lead pricing calculator to model your CPL by channel.
D
Data Validation
Automated checks performed on lead data before scoring or routing. Common validations include phone number connectivity, email deliverability, address verification, and required field completeness. Validation catches junk leads before they waste buyer trust or AI scoring resources.
DNC List (Do Not Call)
A registry of phone numbers that businesses are legally prohibited from calling for sales purposes. The National DNC Registry is maintained by the FTC. Lead distribution platforms should check inbound phone numbers against DNC lists before routing to buyers who make outbound calls.
Duplicate Detection
The process of identifying and rejecting leads that match a previously submitted record. Matching criteria typically include phone number, email address, or custom field combinations within a configurable lookback window (7-90 days). Duplicate leads cost PPL agencies real money through buyer disputes and lost trust.
E
Exclusive Lead
A lead sold to only one buyer. Exclusive leads command premium pricing (2-5x shared lead rates) because the buyer faces no competition for that prospect's attention. Waterfall distribution is the standard method for delivering exclusive leads. Compare economics in our exclusive vs shared leads guide.
F
Fill Rate
The percentage of leads that are successfully delivered to at least one buyer. A 100% fill rate means every lead finds a buyer. Low fill rates indicate insufficient buyer demand, overly restrictive buyer filters, or bid floors set too high. Most healthy lead operations target 85-95% fill rates.
H
Hot Transfer
See Live Transfer.
I
Inbound Lead
A lead generated through channels where the prospect initiates contact: search ads, SEO, social media, landing pages, or referrals. Inbound leads typically convert at higher rates than outbound leads because the prospect has demonstrated active interest.
IVR (Interactive Voice Response)
An automated phone system that routes callers through a menu of options before connecting them to a live agent. In pay-per-call operations, IVR screens callers for basic qualification (location, intent, case type) before transferring to a buyer.
J
Jornaya LeadiD
A lead authentication and compliance platform that tracks consumer interactions across web forms and phone calls. LeadiD tokens create an auditable trail proving when and how a lead interacted with a form, supporting TCPA compliance and dispute resolution.
L
Lead Aggregation
The practice of collecting leads from multiple sources (publishers, affiliates, ad campaigns) into a single platform for scoring, deduplication, and distribution. Aggregators earn margin by buying leads at wholesale and selling at retail. See the lead aggregation guide.
Lead Broker
A business that buys leads from generators and sells them to end buyers (law firms, insurance agents, contractors) at a markup. Brokers typically do not generate leads themselves. They add value through quality scoring, compliance verification, and buyer matching. Read how to sell leads for the full playbook.
Lead Distribution Software
A platform that automates the routing of leads from sources to buyers based on configurable rules. Core functions include ingestion, validation, scoring, routing, delivery, and reporting. The best lead distribution software supports multiple distribution methods, AI scoring, and real-time P&L tracking.
Lead Marketplace
An online platform where multiple sellers list leads and multiple buyers bid on or purchase them. Marketplaces typically use ping-post to facilitate real-time competition. See the lead marketplace guide.
Live Transfer
A call-based lead delivery method where an agent speaks with the prospect first, qualifies them, and then transfers the call directly to the buyer while the prospect is still on the line. Live transfers produce the highest conversion rates (15-30%) but also command the highest pricing ($50-$300+ per transfer). See our live transfer leads guide.
Lookback Window
The time period a duplicate detection system checks against when evaluating whether a lead is a duplicate. Common windows are 7, 14, 30, or 90 days. Shorter windows allow the same person to re-enter the system sooner; longer windows prevent repeat contacts but may block legitimate re-inquiries.
M
Margin Per Lead
Revenue received from a buyer minus the acquisition cost of that lead. The most important metric for PPL agencies. Tracked per source, per buyer, per campaign, and per vertical. Real-time margin tracking (not end-of-month reconciliation) is the standard for modern lead distribution platforms. See how to price leads for margin optimization strategies.
MVA Leads
Motor vehicle accident leads, a high-value subcategory of personal injury legal leads. MVA leads are among the most expensive lead types, ranging from $150-$500+ per lead depending on case severity and geography. See our MVA leads guide.
O
One-to-One Consent (FCC Rule)
An FCC regulation effective January 2025 requiring that a consumer's consent to be contacted applies to one specific, named seller rather than a blanket list of companies. This rule fundamentally changed how lead generators collect and distribute consent, requiring explicit per-buyer consent language on web forms.
P
Pay Per Call
A performance marketing model where advertisers pay for inbound phone calls rather than clicks or form submissions. Calls are tracked via unique phone numbers and routed through IVR or direct transfer. Common in legal, insurance, home services, and healthcare verticals. See pay per call marketing.
Pay Per Lead (PPL)
A pricing model where advertisers pay a fixed price for each qualified lead delivered. The lead generator assumes the risk of ad spend and only gets paid when a lead meets agreed-upon criteria. PPL is the dominant model for agencies selling to law firms, insurance agents, and home service contractors. See what is pay per lead.
Ping
The first step in ping-post distribution. A partial lead (stripped of personally identifiable information) is sent to multiple buyers simultaneously for evaluation and bidding. The ping typically includes non-PII fields like zip code, lead type, injury type, or property details.
Ping-Post
A two-step lead distribution method where sellers send partial lead data (the ping) to multiple buyers, who evaluate and bid in real time, and the winning buyer receives the full lead (the post). Ping-post maximizes revenue per lead by creating buyer competition. See ping-post lead distribution explained.
Post
The second step in ping-post distribution. After a buyer wins the bid, the full lead data (including PII: name, phone, email) is delivered to the winning buyer's endpoint. Post delivery typically happens within milliseconds of bid acceptance.
P&L Dashboard
A profit-and-loss reporting interface that shows revenue, cost, and margin in real time. In lead distribution, P&L dashboards track these metrics per source, per buyer, per campaign, and per vertical. Essential for identifying which traffic sources are profitable and which are losing money.
R
Rejection Rate
The percentage of delivered leads that a buyer rejects (does not accept or returns). High rejection rates indicate data quality issues, poor targeting, or misaligned buyer expectations. Most platforms allow buyers to provide rejection reasons, which feed back into scoring and routing optimization.
Return Rate
The percentage of leads that buyers return after initial acceptance, typically due to bad contact information, duplicate submissions, or failure to meet agreed-upon criteria. Return policies vary by platform and buyer agreement. High return rates erode seller margin and buyer trust.
Revenue Per Lead (RPL)
The average revenue generated from selling a single lead. Calculated by dividing total revenue by total leads sold. RPL varies by vertical, lead quality, exclusivity, and distribution method. Ping-post typically produces 15-30% higher RPL than fixed-price waterfall.
Round Robin
A distribution method that assigns leads equally across all eligible buyers in rotation. Buyer A gets lead 1, buyer B gets lead 2, buyer C gets lead 3, then back to A. Round robin ensures balanced volume distribution but does not optimize for buyer performance or bid price. See lead distribution models.
S
Shared Lead
A lead sold to multiple buyers simultaneously (typically 3-5). Shared leads are priced lower than exclusive leads because buyers compete with each other to contact the prospect first. Conversion rates on shared leads are 35-45% lower than exclusive leads (MarketingSherpa, 2024).
Speed to Lead
The time elapsed between a lead submitting a form and the first human contact attempt. Research consistently shows that faster speed to lead produces higher conversion rates. The industry benchmark is under five minutes, but only 7% of companies achieve this (Drift, 2024).
T
TCPA (Telephone Consumer Protection Act)
A federal law regulating telemarketing calls, auto-dialed calls, pre-recorded messages, and text messages. Violations carry penalties of $500-$1,500 per unsolicited contact. TCPA compliance is mandatory for any lead distribution operation that routes leads for phone-based follow-up. See TCPA compliance for lead generation.
TrustedForm
A consent verification product by ActiveProspect that creates an auditable certificate for every lead form submission. The certificate captures a video replay of the consumer's interaction, the consent language displayed, and a timestamp. TrustedForm certificates are the industry standard for proving TCPA compliance in lead transactions.
V
Vertical
An industry category within lead generation. Common verticals include legal/PI, insurance, mortgage, solar, and home services. Each vertical has different lead pricing, compliance requirements, buyer expectations, and distribution patterns. Lead Distro AI supports all major verticals. See vertical-specific guides for legal, insurance, mortgage, solar, and home services.
W
Warm Transfer
A live transfer where the initial agent introduces the prospect to the buyer's rep before disconnecting. The agent briefs the rep on the prospect's situation while the prospect listens, creating a smoother handoff than a cold transfer (where the call is transferred without introduction).
Waterfall Distribution
A distribution method that routes each lead to buyers in priority order. The first buyer whose filters match accepts the lead. If they reject or do not respond within the timeout window, the lead falls to the next buyer in line. Waterfall is the standard method for exclusive lead delivery. See lead distribution models.
Webhook
An HTTP callback that sends lead data from one system to another in real time when an event occurs (e.g., new lead submitted, lead scored, lead delivered). Webhooks are the primary integration method for connecting lead sources to distribution platforms and distribution platforms to buyer CRMs.
Weighted Distribution
A distribution method that routes leads proportionally based on assigned weights. A buyer weighted at 60% receives roughly 60% of eligible leads, while a buyer at 40% receives the remainder. Weights can be based on buyer performance, contract terms, or revenue targets.
FAQ
What is lead distribution software?
Lead distribution software automates the routing of leads from sources (web forms, ads, affiliates) to buyers or sales reps based on configurable rules. Core functions include ingestion, validation, scoring, routing, delivery, and reporting. The best platforms support multiple distribution methods, AI scoring, and real-time P&L tracking. See our guide on what is lead distribution software for a complete overview.
What is the difference between lead distribution and lead routing?
Lead routing is one step within lead distribution. Routing is the logic that determines which buyer gets a specific lead. Distribution is the broader system that manages the entire flow: ingestion, validation, scoring, routing, delivery, tracking, and reporting. All lead distribution software includes routing, but routing alone is not distribution.
What does ping-post mean in lead generation?
Ping-post is a two-step lead auction process. The seller sends a partial lead (the ping) with non-PII data to multiple buyers simultaneously. Buyers evaluate the ping and respond with a bid or rejection. The highest bidder receives the full lead (the post) with all PII. Ping-post maximizes revenue per lead by creating real-time buyer competition.
What is the difference between exclusive and shared leads?
An exclusive lead is sold to one buyer only. A shared lead is sold to multiple buyers (typically 3-5). Exclusive leads cost 2-5x more but convert at significantly higher rates because the buyer faces no competition. Shared leads are cheaper but have 35-45% lower conversion rates. The right model depends on your vertical, pricing, and buyer expectations.
What is TCPA compliance in lead generation?
TCPA compliance means following the Telephone Consumer Protection Act when generating and distributing leads for phone-based follow-up. Key requirements include obtaining prior express written consent before calling, maintaining do-not-call lists, and (since January 2025) ensuring one-to-one consent where consumers agree to be contacted by a specific named company rather than a blanket list.
