Free Robots.txt Checker

Q: Does Novaverb estimate missing numbers?

No. Missing evidence produces an unavailable or incomplete state instead of an invented metric.

Q: What can I do after this free check?

Connect the target to a Novaverb workspace to save evidence, monitor changes, and run site-wide analysis.

Check and test any website's robots.txt for free. See its HTTP status, crawl rules grouped by user-agent, allow and disallow counts, any declared sitemaps, and whether it accidentally blocks the whole site.

Submit a public URL, domain, or keyword. Novaverb will show only the evidence this tool can actually retrieve or measure.

Evidence model

Know what the result proves

Each free check separates measured evidence from interpretation, and interpretation from the deeper work available in a connected workspace.

database

1. Source

Live robots.txt fetch. The result identifies where its evidence came from.

rule

2. Boundary

The checker fetches /robots.txt and reads its directives. robots.txt is a crawl directive, not access control or index removal; this tool does not simulate a specific crawler's policy.

3. Next action

Use the finding to verify a problem, then connect a workspace when you need history, monitoring, or site-wide analysis.

Robots.txt explained

Test your robots.txt without overclaiming what it does

robots.txt tells compliant crawlers which paths they may request. It is the first file most crawlers fetch, so a single wrong line can quietly keep a whole site out of search — or let private paths be crawled.

What to check

Location — the file must live at the domain root and return HTTP 200 as plain text.
User-agent groups — each group's Allow/Disallow rules apply only to the agents it names; an empty Disallow after User-agent: * can block everything.
Declared sitemaps — publish the sitemap's absolute URL here so crawlers can discover it.
Validation boundary — this page checks HTTP reachability and directive evidence; it is not a full RFC 9309 parser or a Search Console inspection.

Why it matters for SEO and AI discovery

A clear robots.txt reduces ambiguity for search and AI crawlers. Novaverb can use this signal as part of a broader crawl and technical evidence model, alongside indexability, canonicals and internal links.
