CRAWL & INDEX INTELLIGENCE

Know who can reach your website.
And why access is allowed or blocked.

A live audit of crawler access controls: interpret robots.txt, test server responses, trace sitemaps, and expose conflicts between crawl and indexing decisions.

  • Declared policy + live response
  • Search and AI crawlers
  • Explainable, exportable report

Start from any page

A site report—not a one-line check.

We inspect the page, domain, control files, and server response as each crawler. The report does not grade SEO content.

We make limited public requests only and reject internal addresses and non-standard ports. Results are cached briefly to reduce load.

Six layers in one report

From raw directives to an actionable decision.

We do not stop at file existence. We connect each rule to the path, server response, and page signals, then show conflicts and evidence.
01

robots.txt engine

User-agent groups, rule precedence, wildcards, end anchors, errors, and non-standard directives.

02

Crawler matrix

Declared policy and live responses for Google, Bing, OpenAI, Anthropic, and Perplexity.

03

Sitemaps

Discover sitemap indexes and child files, count entries, and detect Googlebot conflicts.

04

Indexing decisions

meta robots, X-Robots-Tag, canonical, and their relationship to crawler access.

05

Host normalization

HTTP, HTTPS, www, and non-www: do they converge on one destination or create fragmented copies?

06

Pre-deployment simulator

Test any path against every crawler using published rules and identify the winning rule and line number.

What does the score measure?

Consistency—not preference.

You may block GPTBot while allowing OAI-SearchBot, or block an entire section from Googlebot. The tool does not treat blocking as an error. The score drops when the file is unavailable, rules conflict, a sitemap contradicts the policy, or a WAF blocks a crawler the policy allows.

Important: The report measures current access eligibility and signals; it cannot prove that a search engine has actually indexed the page.

Understanding the result

Details that prevent incorrect decisions.

Does robots.txt prevent a page from appearing in search?

It primarily controls crawling. A URL may still appear without a snippet if discovered elsewhere. To prevent indexing, use noindex while allowing the crawler to read the page.

Why inspect both policy and live response?

A rule may allow a crawler while Cloudflare or the WAF returns 403 or 429. The policy is then correct but practical access fails.

Does llms.txt affect the score?

No. It is shown only as an emerging optional signal. Its absence is not penalized and it is not presented as a replacement for robots.txt.

Is this an SEO audit tool?

No. It does not grade content, keywords, headings, links, or performance. SEO auditing remains a separate system so each result stays precise and understandable.
