Why calls from the search results page never get tracked
Search "emergency locksmith" on a phone. There is a call button on the ad. Tap it and the call connects. No website loaded, no page viewed, no tag fired.
For a locksmith, a windscreen fitter, a plumber, that call is the business. In the accounts we see it is the largest single conversion source. And the tracking that most agencies sell, however sophisticated, lives on the website. It cannot see a call that never got there.
What Google gives you
Google does count these calls, through call reporting. A call lasting longer than the threshold you set, commonly thirty seconds, is recorded as a conversion. That is all it is: a duration. The person booking a £300 replacement and the person asking whether their job is still on for Thursday both count.
There is no quality layer. Nothing goes back to Google saying which calls mattered, so the bidding treats them all as equally desirable and buys more of whatever is cheapest.
What closes the gap
Google's Call Details Forwarding passes the click ID for calls to call assets and call-only ads that last over fifteen seconds, delivered with the call along with the campaign and ad group. A call tracking number on those assets receives it. CallRail does this well.
With the click ID attached, the call can be scored and matched to what happened next. Was it a new enquiry? Did it book? Did it complete? That answer, with a value, goes back to Google as an offline conversion. The machine now learns from calls that became jobs, not calls that lasted thirty seconds.
The Google Business Profile is the other route. CallRail can swap the listing's primary number for a tracking number while keeping the real one as secondary for citation consistency. Those calls carry no click ID, so they stay reporting-only, but for the first time you know how many there are and what they were.
Details that catch people out
Account-level call reporting has to be on. The mobile click-to-call integration must be disabled before enabling Call Details Forwarding or calls double count. Google's own call reporting stays on beside it. UK tracking numbers need identity verification on signup, so allow a week.
Site-side click ID capture is table stakes. Capturing the call that never touched the site is the difference.
