Why did my Google Ads brand search CPCs double after Google auto-enabled AI Max?
Google opted broad match advertisers into AI Max on 1 September and auto-enabled AI-extracted promotions in October, so brand CPCs roughly doubled and Performance Max began bidding against advertisers' own brand campaigns, with nothing in the account flagging what changed.
Who has it: In-house PPC managers, agencies and small business owners running Google Ads brand and Shopping campaigns.

Heard in public
“Google opted in a ton of advertisers using broad match keywords into AI max for search automatically on Sep 1.”

An auto-setting watchdog for Google Ads: snapshot every account and campaign setting across an MCC daily, flag Google-initiated opt-ins such as AI Max or automated promotions, and tie each change to shifts in CPC and brand cannibalisation.
Tools that solve this
4 named so far, and where each one stops.
- Google Ads change history
Logs edits, but Google-side opt-ins and new defaults are easy to miss and not visible across an MCC.
- Optmyzr
Rule-based alerts and audits; catches performance swings but not every new account-level auto setting.
- Adalysis
Audits and alerts on ads and bids, with the same gap on platform-side opt-ins.
- Google Ads scripts
Can monitor almost anything, but someone has to write and maintain them.
How you might build it
- 01Google Ads API
- 02Daily settings snapshot and diff
- 03Anomaly detection on CPC and impression share
- 04Search term and brand overlap analysis
- 05MCC level alerting
