About GoogleDigitalAssetLinks

The Digital Asset Links bot verifies statements lists made by website operators.

SEO crawlers map links, keywords and technical issues for SEO tools and backlink databases. They help the tool's customers, often your competitors, rather than you. Rate limit or block the ones you do not use.

GoogleDigitalAssetLinks user agent

GoogleDigitalAssetLinks identifies itself with this user agent string:

  • GoogleAssociationService/

Anyone can copy a user agent string. Transfon Security also checks where each request comes from, so a request that claims to be a known crawler but comes from the wrong network is treated as a fake, not as the real crawler.

How to block GoogleDigitalAssetLinks in robots.txt

We have not confirmed whether GoogleDigitalAssetLinks follows robots.txt. Add a rule, then check your logs to see that it stopped. robots.txt is a plain text file at the root of your domain, such as https://example.com/robots.txt.

Things to know

  • Each host needs its own file. Rules on www.example.com do not apply to shop.example.com.
  • A crawler obeys only the most specific group that names it. Once you add a User-agent: GoogleAssociationService group, GoogleDigitalAssetLinks ignores your User-agent: * rules, so repeat any that should still apply.
  • The user agent name is not case sensitive. We take GoogleAssociationService from GoogleDigitalAssetLinks's user agent; check Google's own documentation if it publishes a different robots.txt name.
  • Crawlers cache robots.txt, so changes can take up to a day to apply. Disallow stops crawling but does not remove pages already collected or indexed.

Limits of robots.txt

  1. GoogleDigitalAssetLinks may not follow the rule. robots.txt is a request that nothing enforces, and we have not confirmed that GoogleDigitalAssetLinks follows it. Check your logs after adding a rule.
  2. The user agent could be fake. robots.txt matches the name a request claims. Anyone can send GoogleDigitalAssetLinks's user agent, and a scraper using it is not bound by Google's robots.txt policy. Only checking the source network tells a real GoogleDigitalAssetLinks from a fake one.

Treat robots.txt as a statement of your policy, and enforce it where requests arrive.

Is robots.txt enough to block GoogleDigitalAssetLinks?

No. robots.txt is voluntary, so GoogleDigitalAssetLinks may not follow it, and anyone can send GoogleDigitalAssetLinks's user agent, so a fake GoogleDigitalAssetLinks ignores your rule. Enforce the rule where requests arrive, at your WAF, and check the source network.
