Robots.txt Tester
Fetch and analyse any website's robots.txt file. Check for crawl directives, sitemap declarations, and common configuration issues.
What is robots.txt and Why is it Important for SEO?
The robots.txt file is a text file at the root of a website that tells search engine crawlers which pages they can and cannot access. This free robots.txt tester fetches and analyses the file for any domain, checking for sitemap declarations, crawl directives, and common misconfigurations.
Why it matters: A misconfigured robots.txt can accidentally block search engines from crawling important pages, or fail to block pages you don't want indexed. Common issues include accidentally disallowing the entire site with "Disallow: /", missing sitemap directives, and blocking CSS/JavaScript files that Googlebot needs for rendering.
Best practices: Always include a Sitemap directive pointing to your XML sitemap. Use specific Disallow rules rather than blocking entire directories. Test your robots.txt regularly to ensure important pages remain accessible to crawlers like Googlebot, Bingbot, and other search engine spiders.
What is the Robots.txt Tester & Generator?
Validate your robots.txt file to ensure search engine crawlers can access your important pages while blocking private or low-value sections. Test specific URLs against your robots.txt rules and generate properly formatted directives for any use case.
Example: discovering that your entire blog is accidentally blocked
You paste your robots.txt into the tester and check the path /blog/. The tool flags a “Disallow: /blog” rule you didn’t realise was there — leftover from a staging migration. Every blog post has been invisible to Google for weeks. Removing that single line and re-testing confirms all blog URLs are now crawlable.
/blog/ was disallowed
None were being indexed
Delete one line, re-test

Why This Matters for SEO
A misconfigured robots.txt can accidentally block search engines from crawling your most important pages, rendering them invisible in search results. Conversely, allowing crawlers to access low-value or duplicate pages wastes your crawl budget. Regular testing ensures your crawl directives align with your SEO strategy.
