Phone call conversions
Phone call conversions count phone calls as conversions and attribute them to the ad or campaign that drove them. Ad platforms use call extensions with dynamic forwarding numbers, or track clicks on a phone-number link on the website, to connect a call back to its source. This page explains how call tracking works, what it can attribute, and the privacy considerations around recording or measuring calls.
How calls get attributed
There are two common mechanisms. Call extensions and call-only ads can show a dynamic forwarding number unique to the ad interaction; when that number is dialed, the platform attributes the call to the click. Alternatively, a click on a tel: link or a 'call' button on the website is tracked as a conversion event.
Google documents both approaches for counting calls from ads and from website call buttons as conversions.
Limits and privacy
Call tracking attributes calls that flow through the tracked number or button. A user who copies the number and dials later, or calls from a saved contact, is not attributable. Forwarding numbers also need careful setup to avoid breaking the caller experience.
Because calls involve personal data — and recording adds further obligations — measurement must respect consent and local telecom and privacy law. Configure call measurement as a count of call events, not as surveillance of conversations.
- Forwarding numbers tie dialed calls to ad clicks
- tel: link / call-button clicks tracked as events
- Manually dialed calls are not attributable
How it appears in analytics and logs
A call conversion logged against a campaign means a forwarding number or a tracked click on a phone link tied the call to that source; calls dialed manually from memory are not attributable.
Diagnostic use case
Measure campaigns that drive phone enquiries — common for local services, sales, and high-consideration purchases where the conversion is a call rather than a form.
What WebmasterID can help detect
WebmasterID can record clicks on a tel: link as a CTA event, giving you a first-party signal of call intent on the page even when the call itself is handled by a phone system.
Common mistakes
- Assuming every phone enquiry is attributable to a campaign.
- Recording calls without meeting consent and legal requirements.
- Ignoring calls that bypass the tracked forwarding number.
Privacy and accuracy notes
Call measurement and any recording are subject to consent and local law; this is educational, not legal advice. Treat phone numbers as personal data.

- Store visit conversions
Store visit conversions are an ad-platform measurement that estimates how many people visited a physical store after seeing or clicking an ad. Google documents that store visits are modeled and aggregated, derived from anonymized, consented location data and statistical extrapolation rather than tracking specific individuals into a shop. This page explains the modeled nature of the metric and how to read it responsibly.
- Offline conversion import
Offline conversion import (OCI) connects events that happen away from the website — a sales call that closes, an in-store purchase, a qualified lead in a CRM — back to the online ad click that began the journey. It works by capturing a click identifier (such as Google's GCLID) at the start and later uploading the offline outcome keyed to that identifier, closing the online-to-offline attribution loop.
- Conversion import from CRM
Conversion import from a CRM connects later, offline business outcomes — a qualified lead, an opportunity, a closed-won deal — back to the marketing click that started the journey. The click is captured with an identifier (such as Google's GCLID), stored in the CRM, and uploaded back to the ad platform when the outcome occurs. This lets optimization target real revenue events, not just form fills. This page explains the flow and its requirements.
