Online, every click leaves a trail. Phone calls do not — unless you use call tracking. Call tracking connects each call to the campaign, ad, keyword or page that produced it, records the conversation and tells you whether the call became billable. It is the foundation of every profitable pay-per-call operation.
The building blocks
- Tracking numbers. Phone numbers you own on a call tracking platform. Each one forwards to the real destination (the buyer's queue or your call center) while logging the call.
- Static numbers per source. One number per channel or campaign — a TV station, a mailer, a Facebook campaign. Simple and reliable.
- Dynamic number insertion (DNI). A script on your website swaps the number shown to each visitor based on where they came from. With a pool of numbers, you can attribute calls down to the keyword or ad.
- Routing. Rules that send each call to the right buyer by time, state, caller ID, capacity or bid.
- Recording and transcription. Evidence for disputes, quality checks and training.
Buffers and billable calls
Buyers rarely pay for every call. They pay when a call meets the buffer — a minimum duration such as 90 or 120 seconds — and other rules like a duplicate window or accepted states. Your tracking platform should mark each call as billable or not using the same rules, so your numbers match the buyer's.
Send conversions back to the ad platforms
This step separates profitable publishers from the rest. If Google Ads only counts "a call happened", its bidding will chase cheap, short calls. Most call tracking platforms can send billable calls back to Google Ads, Microsoft Ads and Meta as offline conversions, with the payout as the value. The algorithm then optimises for the calls you are paid for.
What to look at every day
- Calls by source and the billable rate for each.
- Average call duration and the share of very short calls (signs of misdials or poor targeting).
- Calls outside buyer hours (wasted spend — fix your ad schedule).
- Repeat callers (duplicates are usually not billable).
- A few recordings from each source.
Choosing a platform
Popular call tracking and routing platforms used in pay per call include Ringba, TrackDrive, Retreaver, Invoca and CallRail — each with different strengths in routing, ping-post bidding, integrations and pricing. Pick one that supports DNI, buffers, recording, conversion postbacks and the integrations your buyers use.
Privacy and recording notices
Some US states and many countries require all parties to consent to call recording. A short notice at the start of the call ("this call may be recorded for quality") is standard practice. Store recordings securely and keep them as long as your contracts and regulations require.
