HOW TO READ A PROFILE

Four things every profile tells you.

Enough to decide, and to check what your logs claim.

TOKEN

The robots.txt token

The exact name to put in a User-agent line, with copy-ready rules to block or allow it.

VERIFY

How to verify a visit

Published IP ranges, reverse DNS or signed requests. A user agent alone is only a claim.

ROBOTS

Whether it obeys robots.txt

Some bots fetch only when a person asks and may not follow robots.txt; a few ignore it entirely.

IMPACT

What blocking it costs

Training crawlers can go without touching rankings; search crawlers cannot.

FAQ

About the crawler directory.

Where the data comes from, and what it can tell you.

Where does this data come from?

From the registry NdovuSEOLabs uses to classify crawler traffic in Crawl Analytics. Each entry is built from the operator’s own documentation, and each profile shows when that was last checked. Registry version 2026-10-29.1.

What does “can be verified” mean?

The operator publishes a way to check that a request really comes from its bot: IP ranges, reverse DNS or signed requests. A user agent alone is only a claim, and anyone can copy one.

Does blocking AI training crawlers hurt my SEO?

Blocking a training crawler such as GPTBot or ClaudeBot does not change your search rankings. Blocking a search crawler such as Googlebot or Bingbot removes your pages from those results, and blocking AI search crawlers can keep you out of AI answers.

Why is a bot I see in my logs missing?

The directory lists the bots NdovuSEOLabs recognises, and adds one when its operator documents it, so every entry can be checked.

How do I see which bots visit my site?

Install the WordPress plugin or connect your server or CDN logs. Crawl Analytics then counts each bot’s requests and separates verified visits from impostors.

See which of these crawlers visit your site.

Crawl Analytics reads your own server and CDN logs and checks each claim against the operator’s published IP ranges and DNS.
