Robots.txt Tester
Analyze your site's robots.txt file for format errors, crawl rules, and get AI-powered optimization suggestions.
Enter your site's URL to run the analysis
The tool fetches your live robots.txt file directly from your server, parses every directive, and checks the formatting line by line.
You will receive: The format status. The total number of user-agents addressed. The total rule count.
A comprehensive analysis of the crawl rules, including: All Allow and Disallow directives. Sitemap references. Any specified crawl-delay settings.
If your robots.txt has real configuration in it (not just the default allow-everything or empty file most sites start with), the tool also generates a short AI-powered suggestion, a specific, rule-aware note on what might be worth tightening up or reconsidering.
While robots.txt is a small file, mistakes are usually invisible until the negative consequences surface.
This could have an unintended consequence where pages you intended to index being quietly excluded from search results.
Or an entire section of your site being completely blocked from crawling due to a single, overly broad Disallow rule that initially seemed harmless.
You must be careful to consistently recheck the file to ensure the final outcome matches your expected behavior.
Format errors are the sneaky part. Search engines can be forgiving of malformed robots.txt files, they'll seem just ignore the broken line and move on, which means a typo can sit there for months doing nothing useful and nobody notices. Checking format validity directly is the only way to catch that kind of silent failure before it costs you crawl budget or visibility on pages that actually matter.
It's also worth revisiting robots.txt any time your site structure changes, a new staging subfolder, a plugin generating URLs you didn't expect, or a CMS switch that inherits a completely different default file. A quick test after any of those changes confirms the rules still say what you think they say, rather than finding out the hard way when traffic to a section quietly drops.
