Questions people ask

When does Google migrate Search campaigns to AI Max?

Eligible Search campaigns began auto-migrating on 1 September 2026, with Dynamic Search Ads following from February 2027. The practical change is that AI Max expands matching well beyond your keywords, so the search terms report needs a weekly pass for negatives.

When do Local Services Ads start charging for missed calls?

From 1 October 2026 a missed call during your business hours counts as a billable lead if the caller stays on the line for more than 20 seconds. Key-press routing delays the timer until the caller presses a key, which is the cheapest defence.

What is changing with Microsoft Ads Max CPC?

From 1 October 2026 new campaigns using standalone Maximize Conversions, Maximize Conversion Value or Maximize Clicks cannot set a Max CPC. Existing campaigns keep theirs. Target CPA, target ROAS, portfolio strategies and Target Impression Share still allow a cap.
