Google is phasing out standalone Call Ads in favor of Responsive Search Ads with call functionality as announced in October 2024.
Now, a new help page has been published, detailing the process and necessary steps for the transition.

Key Changes:
- Call ads must now include a landing page (final URL).
- A business name is required at the campaign or account level.
- New Call Ads creation will soon be disabled, and existing ones without a final URL won’t be migrated.
If you use call ads, transition to Responsive Search Ads to maintain performance.
