Phone-call attribution

1

What you need probably already done

• Our capture script on the website visitors browse before calling
• Inbound calls landing in your CRM (a phone number in the sub-account, so calls create contacts and call records)

2

Tell us the website's domain the one setting

Open the location in Pipeline Signals → Call attribution → enter the site's domain (e.g. clinic.example.com) → save. This scopes matching strictly to that client's own traffic.

How the matching works and when it declines

When someone clicks an ad and browses the site, we note the visit (no personal data — just click IDs and timestamps). If a call comes in while they're on the site or within 15 minutes of their last page view, and theirs is the only ad-visit in that window, the caller inherits the full click attribution — as if they'd filled a form.

If two ad visitors are on the site at once, we decline to guess. The call still reports to Meta matched by the caller's (hashed) phone number — a genuine match key, just a weaker one. A wrong click ID would poison your ad account's learning; a declined match never does.
