Frequently Asked Questions

Should I Block Google-adstxt?

If you run ads, confirm Google-adstxt's purpose before blocking it. Some intelligence gatherers measure ad placements or evaluate pages for brand safety, and blocking those agents can interfere with advertising systems. If this one serves a different purpose, weigh any research visibility against sharing business or page-level data with third parties. Almost none of the top websites we track currently have robots.txt rules for Google-adstxt.


Does Google-adstxt Follow Robots.txt Rules?

Yes. Google-adstxt is expected to follow robots.txt directives, so a disallow rule is the appropriate first step. Automatic Robots.txt can add and maintain that rule, while Agent Analytics lets you verify whether Google-adstxt respects it.


Does Google-adstxt Access Private Content?

No special access. Google-adstxt can read publicly available pages but cannot bypass authentication. Assume anything you publish openly may be collected.


Why Is Google-adstxt Visiting My Website?

A client of Google may be gathering competitive intelligence, measuring advertisements, or evaluating content for brand safety. The pages requested reflect that client's objective.


How Can I Tell if Google-adstxt Is Visiting My Website?

Agent Analytics tracks Google-adstxt visits in real time alongside every other known AI agent, crawler, and scraper. You can also check your server logs for requests whose user-agent string contains "Google-adstxt". Look for repeated requests to the same small group of commercial or ad-supported pages. Because Google-adstxt does not publish a verification method, any client can claim its identity and a log match is only a clue.
