How do I track phone calls from Google Ads?
Short answer
Track three kinds of call separately: calls placed straight from the ad, calls from your website after an ad click, and taps on the phone number on your mobile site. Google Ads can measure the first with a forwarding number. The second needs a number on your site that changes for visitors who came from an ad.
You track phone calls from Google Ads by measuring three separate paths: calls placed straight from the ad, calls made from your website after someone clicked an ad, and taps on the phone number on your mobile site. An account that seems to produce few calls may be measuring only one of the three. The setup isn’t difficult, but each path needs its own piece.
The three paths a call can take
| Path | How it’s tracked | What you learn |
|---|---|---|
| The person calls from the ad without visiting your site | Google shows a forwarding number in the ad and passes the call to your line | That a call happened, how long it lasted, and which campaign it came from |
| The person clicks the ad, reads your page, then dials | A small script on your site swaps the displayed number for visitors who arrived from an ad | The campaign, and often the keyword, behind the call |
| The person taps the number on your mobile site | The tap is recorded as an event on the page | That someone tapped. A tap isn’t proof that a call connected |
The third path is the weakest evidence, so I treat it as a backstop and not as the main count. If the second path is working, most of those taps are already being counted as real calls.
Deciding what counts as a conversion
A call should count only when it’s likely to be a customer. A conversion is the action you tell Google Ads to treat as a success. For calls, Google lets you set a minimum length, so that hang-ups and wrong numbers are left out. Length is a rough filter. A long call can be a supplier, and a short one can be a booked job. It’s still better than counting every ring, because automated bidding goes looking for more of whatever you count.
Google’s own tracking, or a separate service
Google’s built-in tracking is enough to start with, and it only sees calls that came through an ad. A separate call tracking service does the same number swap for every source: ads, unpaid search, your Google Business Profile, a mailer. That’s what lets you put paid and unpaid calls on one page. With call tracking set up across every source, your real number still has to stay where Google and the directories expect it. Calls that come from Google Maps are a separate case.
Some services can record calls. Recording has consent rules in California, so it should be set up properly before the first call is recorded. That’s a question for someone qualified to advise you, and tracking works without it.
From tracked call to booked job
Tracking tells you a call happened, and nothing about whether it became work. Someone in the office has to mark each tracked call: new customer or not, booked or not. Once that is done, the report can show what a booked job cost in each campaign. That figure decides where the budget goes in search ads.
How to test that it works
Before trusting the numbers, try each path yourself. I’d start with these checks:
- Search for one of your own keywords on a phone, call from the ad, and confirm the call appears in the account.
- Click an ad, check that the number on the page changed, call it, and confirm the call reached your office.
- Visit the site directly, without an ad, and confirm you see your real number.
Clicking your own ad costs you a click, so do it once and not daily. Reports can lag, so check again the next day before deciding something is broken.
