Free Robots.txt Checker
Check whether any site has a robots.txt file, whether it references your XML sitemap, and whether it's accidentally blocking search engines.
A missing or misconfigured robots.txt can quietly stop search engines from finding your most important pages — or fail to point them to your sitemap at all. The siteIQ Robots.txt Checker fetches the live file and tells you exactly what's there.
Enter a URL to see whether robots.txt exists, whether it references your XML sitemap, and what it's telling crawlers to avoid.
What this tool checks
File exists
Whether /robots.txt is present and reachable at all.
Sitemap reference
Whether robots.txt points crawlers to your XML sitemap.
Disallow rules
What paths are being blocked from crawling, and whether that's intentional.
Crawlability overall
Whether the file is helping or accidentally hurting discovery of your pages.
Why it matters
robots.txt is the first thing a well-behaved crawler reads before touching your site. If it's missing, some crawlers assume everything is open — not always what you want. If it over-blocks, you can accidentally hide entire sections of your site from Google.
Referencing your sitemap in robots.txt is a simple, free way to help search engines discover your pages faster, especially on larger sites.
How to read your results
- If robots.txt is missing, add one — even a minimal file that allows crawling and references your sitemap.
- If your sitemap isn't referenced, add a line like `Sitemap: https://yourdomain.com/sitemap.xml`.
- Double-check any `Disallow` rules — a stray `Disallow: /` blocks your entire site from search engines.
- Re-check after any change to confirm the file is being served correctly.
Frequently asked questions
What is a robots.txt file?
A plain-text file at the root of your domain that tells search engine crawlers which parts of your site they may or may not access.
Do I need a robots.txt file?
It's not strictly required, but having one — even a permissive one that references your sitemap — helps crawlers understand your site faster and avoids ambiguity.
Can robots.txt block a page from ranking?
It can stop a page from being crawled, which usually prevents it from being properly indexed. For pages you want removed from search results, a noindex meta tag is more reliable than robots.txt alone.
Does this tool check any website, or just my own?
It works on any public URL, since robots.txt is a public file every crawler already reads.
