Google Ads just gave AI Max advertisers something they have been asking for since launch: an itemized view of which clicks automation actually chose. A new version of the Search terms and ad combinations report is showing four source columns next to every query and ad pair.
The columns are search term match source, landing page source, headline source and description source. They tell you, row by row, whether an element came from the advertiser or from Google’s AI Max expansion. The report was spotted in a live account by Natasha Kaurra and first reported by PPC News Feed on October 19. Google has not announced the change, and its AI Max reporting help page did not name the columns as of October 25.
What the source columns reveal
Previously, you had to split this work across reports: search terms in one place, asset performance in another. This view puts the pieces together.
- Search term match source shows whether the query came through AI Max expanded matches or through landing pages and URL inclusions.
- Landing page source shows whether the page was advertiser-provided, in the visible rows.
- Headline source and description source show whether the text was written by the advertiser.
In the live account, most rows carried AI Max expanded matches in the match source column, while every visible creative column read Advertiser provided. That means automation found the search term, but the message was still the advertiser’s. What Google labels a machine-generated headline or a final URL expansion pick remains unknown from this account.
A car wash account shows the audit power
The account covers a car wash business across a 30-day window from September 13 to October 12, 2026. In total, 353 clicks were reported. The top row paired “car wash near me” with one headline combination and collected 12 clicks; the next rows had 10, 9, 7 and 7 clicks. The same query appeared across multiple headline sets, including a $49.99 premium wash offer and a $699 ceramic coating deal.
That is the point of the new view. A single query can be split across several headline pairings, each with its own click count. Now you can see the exact combination that drove volume instead of guessing from separate reports. One odd row, labeled DG | PMAX – Window Tint, showed a blank search term and was matched through landing pages and URL inclusions. It could be a privacy threshold or something else, but it is a reminder that some rows may still be hidden.
Why this matters before the DSA migration
AI Max can change the query, the copy and the landing page that win an auction. Until now, that created two accountability gaps. The first was between what you bid on and what triggered your ad. The second was between what you wrote and what Google could serve.
The new columns close the first gap properly. For agencies and brands with strict copy approval, legal disclaimers or regulated claims, this is not just a performance tool. It is a compliance check. A row showing an expanded match plus a Google-generated headline would mean automation is operating on both sides of the click.
The timing matters too. Dynamic Search Ads campaigns are scheduled to be automatically upgraded to AI Max starting in February 2027, with new DSA campaign creation ending in January 2027. Advertisers moving from DSA will land inside this reporting view within months.
What to do now
Open the Search terms page in your AI Max accounts and look for the Search terms and ad combinations tab. Sort by clicks and check rows where the match source is automated. Compare that with the asset source columns. If you see automation on the query side but your own creative on the message side, ask whether your ad copy is aligned with the intent of the expanded query.
Do not treat every expanded match as wasted. Some may reveal high-intent terms you should add as keywords. But until Google publishes the full list of source values and confirms the rollout, treat the report as a useful signal rather than a finished feature.
