Four source columns appeared in the 'Search terms and ad combinations' report for AI Max

Advertisers running AI Max for Search found four new source columns in the Search terms and ad combinations report: Search term match source, Landing page source, Headline source and Description source. Google has not announced them and its help page does not name them.

The visible values for Search term match source were "AI Max expanded matches" and "Landing pages and URL inclusions," which separates queries matched by AI Max expansion from those matched through landing pages and URL inclusions. In the account shown, every visible row listed "Advertiser provided" for the landing page, headline and description sources, so no Google-generated asset appeared in that sample and the full set of possible values is unknown. The account covered September 13 to October 12, 2026. The columns were first shared on October 13 and reported by PPC News Feed on October 19; how widely they have rolled out is unconfirmed.
