FAQ

What robots.txt mistake is most dangerous?

A broad Disallow such as / or a locale prefix can block important pages from crawling even when the sitemap lists them.

Does robots.txt remove indexed pages?

Not directly. It controls crawling. Use noindex or removal tools when you need deindexing behavior.

Why test a single URL?

A specific URL test makes broad rules and wildcard behavior easier to reason about than reading the file abstractly.

robots.txt Tester checks Allow and Disallow rules for a target URL so technical SEO changes can be reviewed before deployment.

It is useful when AI, CMS settings, or manual edits produce robots rules that look simple but accidentally block tool pages, docs, assets, or localized routes.

Use it together with sitemap and Open Graph preview checks before submitting important pages for indexing.

Demo: make sure tool pages are crawlable

Before launching a tool site, test representative URLs from each section. A single broad rule can block pages even when sitemap.xml is correct.

  • Test home, tool, blog, and asset URLs separately.
  • Avoid blocking locale prefixes such as /en or /zh-CN by accident.
  • Disallow /api/ without blocking documentation paths such as /api-error-flow-diagram.

SEO release checklist: test robots rules with real URLs

robots.txt should be reviewed with concrete URLs, not only by reading the file. Locale prefixes, API-looking slugs, and static asset paths are easy to block accidentally on a tool site.

  • Test one page from each major directory before submitting a sitemap.
  • Keep /api/ blocked if needed, but verify similar public slugs are not matched by mistake.
  • Pair robots checks with canonical, hreflang, and sitemap checks for launch review.
