Tokens to look for

User-Agent tokens

Appear in the User-Agent header of its requests.

  • meta-externalads

robots.txt tokens

No robots.txt token is documented for it.

Check a visitor claiming to be meta-externalads

We've filled in its token. Paste the full User-Agent from your logs and the address it came from for a real answer.

Paste the full User-Agent header from your logs. A single token such as GPTBot works too.

Optional

IPv4 or IPv6, as your logs show it. Used only for this check and never stored. Without it, a claim can only come back as can't be verified.

What this means for your site

meta-externalads touches your site for its own reasons. Knowing it is real tells you whether to count it.
