Every official Google change that affects advertisers (Google Ads, Performance Max, Demand Gen, Shopping, Merchant Center, AI Max and the Google Ads API), newest first. Each one links to its source. Last logged Oct 20, 2026.
What to do: If your team already lives in Gemini, connect Google Ads read-only first and compare its answers with the Ads UI before you let it near anything else. Check the Shopify access scopes before you approve the connector.

What to do: List every Customer Match and offline-conversion upload that goes through Data Manager (CRM connectors, scheduled file imports, the API). Before Nov 16, check with Google support or your rep whether your pre-hashed files keep working, then compare match rates before and after the switch. Have privacy or legal sign off on unhashed data being sent to Google's secure environment.
What to do: Nothing to switch on. If you run Search, PMax or AI Max on broad match, expect some AI Mode impressions to be matched on personal context rather than the query alone, so watch search terms and AI Mode reporting for unexpected matches.

What to do: Make sure Merchant Center prices, availability and promotions are accurate. Price-drop alerts and promo surfacing depend on your feed.

What to do: If you or your tools read the old enhanced-conversions-for-leads field, plan the switch to the new setting.

What to do: Find Search campaigns with Display Network on. To keep today's behavior after Feb 2027, Google says to set Display to Low priority with a 50% budget allocation.

What to do: If you sell lingerie, swimwear, sexual wellness or other products where creative can read as suggestive, check your Google ads and landing pages against the new examples. Fix anything that could get restricted before peak season, since limited ads lose YouTube and Display reach.
What to do: Check the new Data Strength Uplift metric once it shows up, and prioritize tag gateway and enhanced conversions if it's low.

What to do: If any Search or Performance Max campaign uses location assets, check what offers your landing pages show: expired sales, member-only or newsletter codes, old prices. Either add your own promotion asset (campaigns with a manual promotion are skipped) or turn it off: Assets > More > Account level automated assets > More > Advanced settings > Automated promotions: Off. To see what Google added, filter Assets by Promotion and look for "Google AI" in the Added by column. Repeat in every account you manage.
What to do: Don't click through the banner on a live container. Export the current version, run the optimization in a fresh workspace, then check in Preview mode that each Google destination fires once per page, that consent behavior is unchanged, and that conversions still record. Review who gets Read access before you publish. Separately, check for custom event triggers with wildcard or regex matches that could now fire on gtag.config events.

What to do: Upload 9:16 full-bleed image assets to Demand Gen so Shorts gets the one-click experience.

What to do: If you run AI Max, plan to audit search terms and landing pages in the new report as soon as it's available.

What to do: Open the AI performance insights in Merchant Center, and enrich product feeds with the conversational details Google recommends before BFCM.
Source: Google Shopping blog ↗
What to do: If you build in-house Google Ads tooling, confirm your Cloud project shows the right access level, and update owner and editor contacts to receive service announcements.

What to do: If you're piping first-party data into several Google tools by hand, see whether Data Manager can replace those connections.
Source: Google Ads & Commerce Blog ↗
What to do: Confirm your reporting connectors and scripts run on v24 or later so the February 2027 v23 sunset doesn't catch you.

What to do: If you lack vertical video, try Asset Studio to cover all Demand Gen inventory.

What to do: Use the multi-campaign test before scaling budgets for Q4 instead of raising spend blind.
Source: Google Ads & Commerce Blog ↗
What to do: List budget-limited Target CPA and Target ROAS campaigns and compare actual CPA or ROAS with the target for the weeks before Aug 17. Set each target to what you'd actually accept. Google says matching recent averages keeps current performance. Or switch to Maximize conversions or Maximize conversion value. Compare lost impression share (budget) with lost impression share (rank) before and after Aug 17 before blaming the drop on this. Give each change 1 to 2 conversion cycles.

What to do: Treat AI summaries as a starting point. Verify anything you act on against the underlying reports.
Source: Google Ads & Commerce Blog ↗
What to do: Add checkout URLs to Demand Gen retail campaigns, and recheck tROAS targets as the new bidding ramps.
