Express crawler rules clearly

Assign rules to a User-agent group, use one directive per line, and review broad Disallow patterns carefully. Robots.txt controls crawling rather than guaranteed search indexing.

Questions

SiteTend Robots FAQ

What does SiteTend Robots check?

It checks syntax, crawler groups, known directives, duplicates, Allow and Disallow conflicts, empty rules, crawl delays, sitemaps, wildcards, broad indexing blocks, and recognized AI crawler groups.

Does robots.txt remove pages from search results?

No. Robots.txt controls crawling requests. A blocked URL may still be known or indexed through other signals.

Does the checker fetch my live robots.txt file?

No. This version analyzes only the file content you paste.

Does SiteTend store pasted content?

No. Analysis runs in your browser, and pasted robots.txt content is excluded from analytics.

Apply the result

From finding to verified fix

Interpret the finding

Treat blocking findings by crawler and path. A syntactically valid rule can still prevent important discovery.

Common causes to inspect

  • Rules copied from staging
  • Over-broad wildcards
  • Conflicting user-agent groups or missing sitemap discovery

Practical next steps

  1. Identify the affected crawler
  2. Test representative important URLs
  3. Publish carefully and verify with the crawler's own tools

What this check cannot prove

The checker does not fetch the live file or prove that a blocked URL is indexed or removed from search.
