ads.txt declares authorised digital-advertising sellers for a publisher. Flowpane observes the root /ads.txt address; it does not assume that the response is a physical file rather than CMS-generated content.

Start with What is ads.txt for purpose, Check details for the assessment, and Common issues for follow-up. A syntactically valid record does not prove a commercial relationship, prevent all fraud or certify a seller. A Site with no advertising needs a relevance decision, rather than fabricated seller records.

Establish whether this Site sells advertising, then obtain the correct advertising-system domain, account ID and relationship from the responsible publisher or partner. Use Review for supported quick corrections and Workbench for full content and drafts. Saving a proposal is separate from publication.
