What the models said for it

Verbatim evidence the judge attached to positive labels.

“Best publisher monetization stack → Google Ad Manager” GPT-5.4 mini · Programmatic · comparative prompt · alternative

“Unified SSP + ad server; AdX access; CTV dominance” Grok 4.1 Fast · Programmatic · comparative prompt · alternative

And against it

Verbatim evidence attached to negative labels. A warning on a product with few labels is a warning; on a product with many, it is one voice among them.

“Google AdX (as an SSP) frequently ranks near the bottom among top SSPs for security and quality issues” Grok 4.1 Fast · Programmatic · negative prompt · hard negative

“Gold standard, but requires 5M+ monthly views” DeepSeek V4 Flash · Video ads · comparative prompt · soft negative

Claim this page

Claiming is free and changes nothing in the data. A claimed page shows a verified contact who is told when each edition publishes and when Google Ad Manager's standing changes by more than the noise floor; the right to propose corrections to the vendor table, meaning names the judge wrote that should or should not read as Google Ad Manager, applied by version and listed in the change log; and a one-line description supplied by the vendor and marked as such.

It does not get any change to labels, shares or verdicts, any preview, or any say over which quotes appear. A verification link goes to your work email; an address at google.com is approved on the spot, any other address is reviewed by hand.

Your name and company appear on the claimed page, or the company alone if you ask below. A title and a LinkedIn address appear there too if you give them, and are left off if you do not. Your email address is never published.
