Robots.txt Tester

What the robots.txt tester does

The robots.txt file lives at the root of a domain and gives search engine crawlers instructions about what they may and may not access. This tool fetches that file and lays it out clearly. It confirms whether robots.txt was found, lists any sitemaps declared inside it, and surfaces the disallow rules that block crawlers from specific paths. Instead of squinting at raw text, you get an organized view of how the site guides the bots that visit it.

How to use it

• Enter a domain, such as example.com, to fetch its robots.txt.
• Check whether the file exists, since a missing file means crawlers face no restrictions.
• Review the disallow rules to see which sections are being kept out of search.
• Confirm your sitemap is listed so search engines can discover all your pages.

The file is fetched live, so you see exactly what crawlers see when they arrive.

Why it matters

A single line in robots.txt can quietly remove an entire site from search results, and mistakes here are common and costly. An overly broad disallow can block pages you want indexed, while a missing sitemap reference can slow how quickly new content is discovered. Verifying the file is part of any healthy SEO routine, especially after a redesign or migration when settings often get carried over by accident. At Digzy Technology, our team in Bali, Indonesia checks robots.txt before and after launch so a stray disallow never hides a client's work from Google. Whether you are auditing your own site or a competitor's, reading robots.txt tells you what the search engines have been instructed to do.
