Common Questions

Frequently asked

Does this show private ad-account performance (spend, CTR, conversions)?

No — this returns only public ad-transparency data (creative content and run dates). Private campaign performance requires the advertiser's own OAuth-connected ad account.

What if no ads are found for the query?

The request fails with a no-match error and is not charged; try a more specific advertiser name or a different platform.

Why does Google need an advertiser name instead of a free-text keyword?

The Google Ads Transparency Center only supports lookup by advertiser, not full-text ad-copy search — the query is resolved to an advertiser first, then that advertiser's ads are returned.
