Pay-Per-Call Glossary

Master the terminology of pay-per-call networks, call routing, compliance, and lead monetization.

This glossary covers essential pay-per-call industry terminology. Whether you're a publisher acquiring callers, a buyer purchasing calls, or a platform operator, understanding these concepts is critical to success in call monetization networks.

A

Auction Routing

A call routing strategy where all buyers simultaneously bid on each incoming call in real time, and the highest bidder is routed the call. Auction routing maximizes revenue by matching each call to the buyer who values it most.

B

Business Hours Routing

Routing rules that direct calls differently based on the time of day and day of week. During business hours, calls route to primary buyers; outside hours, they route to 24-hour support or voicemail.

Buyer (Pay-Per-Call)

In pay-per-call networks, a buyer is a service provider (insurance agent, law firm, contractor, healthcare provider) who pays per verified call routed to them. Buyers compete on price through real-time auctions and set rules for call quality, geography, and service type they'll accept.

C

Call Attribution

The process of connecting an inbound phone call to the specific marketing channel, campaign, keyword, or ad that drove it. Attribution enables measurement of which campaigns generate calls and whether those calls convert to revenue.

Call Duration Billing

A billing model where the price per call varies based on how long the call lasts. Longer calls are charged at higher prices because they represent higher-value customer engagement.

Call Routing

The automated process of directing inbound phone calls to the most appropriate recipient based on pre-configured rules, strategies, and real-time conditions. Routing decisions evaluate caller geography, IVR responses, buyer capacity, and pricing to ensure every call reaches the best possible destination.

Call Tracking

The technical infrastructure that captures, records, and stores inbound phone call metadata including caller phone number, call duration, timestamp, quality metrics, and (optionally) audio recordings for compliance and quality assurance.

Call Widget

An embeddable UI component (button or floating bar) on a website that allows visitors to request an instant or scheduled callback without filling out a form. Call widgets streamline the lead capture process.

Campaign (Pay-Per-Call)

In pay-per-call networks, a campaign is a collection of settings and routing rules for a specific offer or vertical. A campaign includes assigned phone numbers (DIDs), routing strategy, IVR configuration, buyer assignments, caps, and performance goals.

Conversion Upload

The process of sending offline conversion data (like phone calls) back to ad platforms (Google Ads, Facebook) so their algorithms can optimize bids and spend based on real business outcomes, not just clicks.

D

Dynamic Number Insertion (DNI)

A call-tracking technique that displays a unique phone number to each website visitor instead of a static number. When the visitor calls that number, the platform attributes the call to the exact campaign, keyword, ad, and session that drove it.

G

GCLID

Google Click ID, a unique identifier automatically added by Google Ads to every ad click. GCLID is passed through the landing page URL and captured by call tracking platforms to attribute phone calls back to specific keywords, ads, and campaigns.

Geo-Routing

Routing rules that direct calls based on the caller's geographic location (state, region, DMA). Geo-routing ensures calls route only to buyers licensed or available in the relevant area.

I

IVR (Interactive Voice Response)

An automated voice system that plays prompts to callers and collects responses via button presses or voice input. IVRs qualify callers by gathering structured data (service type, zip code, qualification status) before routing them to a buyer, improving conversion rates and call quality.

L

Lead Capture Form

A web form that collects visitor information (name, phone, email, service type) and converts it into an inbound call or outbound callback. Lead capture forms bridge web traffic and phone calls, essential for pay-per-call monetization.

Local Number

A phone number with a geographic area code (e.g., +1-415 for San Francisco, +1-212 for New York) that appears to be local to a specific region. Local numbers increase call rates because callers perceive them as local businesses.

O

Offer Cap

A limit on the maximum number of calls routed to a buyer within a specific time period (daily, weekly, or monthly). Once the cap is reached, the buyer no longer receives routed calls until the cap resets.

P

Pay-Per-Call

A performance-based pricing model where advertisers, lead generators, or service providers pay a fixed amount only when an inbound phone call is successfully connected. Callers are routed through a platform that tracks the call, validates it meets quality standards, and charges the buyer accordingly.

Ping Post

A real-time auction mechanism where a buyer is 'pinged' (sent anonymous call details) before accepting the call, and they 'post' a competitive bid amount. The highest bidder gets routed the call, and only they are charged.

Publisher (Pay-Per-Call)

In pay-per-call networks, a publisher is a lead generator or media buyer who acquires inbound callers through paid advertising and routes them to multiple competing buyers. Publishers capture the arbitrage between their cost-per-call and the buyer's bid or fixed rate.

R

Round-Robin Routing

A call routing strategy that rotates calls evenly across all eligible buyers in sequence. The first call goes to Buyer A, the second to Buyer B, the third to Buyer C, then back to Buyer A. Each buyer receives equal volume.

S

SHAKEN/STIR

Industry standards for caller ID authentication that verify phone numbers are legitimate and not spoofed. SHAKEN/STIR prevents caller ID spoofing fraud and helps carriers block spam.

T

TCPA (Telephone Consumer Protection Act)

A US federal law that regulates telemarketing, auto-dialed calls, SMS messaging, and fax advertising. The TCPA requires prior written consent for telemarketing calls, prohibits certain calling practices, and allows consumers to opt out.

Toll-Free Number

A phone number with area codes 800, 833, 844, 855, 866, 877, or 888 that callers can reach without paying long-distance charges. Toll-free numbers are perceived as more legitimate and professional, especially for national campaigns.

W

Waterfall Routing

A call routing strategy that tries buyers in fixed priority order. Buyer A is the first choice; if unavailable or no-answer, the call falls through to Buyer B; then Buyer C, and so on. Waterfall ensures calls always attempt the highest-priority buyer first.

Weighted Distribution

A call routing strategy that distributes calls across multiple buyers at fixed percentages, such as 60% to Buyer A and 40% to Buyer B. Unlike auction routing (highest bidder wins), weighted distribution maintains consistent volume ratios.
