Explanation
What this checker can tell you
Robots.txt is a crawl-control file. It tells crawlers which paths they are allowed to request. This tool checks whether a specific URL is blocked by the site's robots.txt rules for the crawler you choose.
Honest about limits
This does not confirm whether Google indexed a page. It checks crawl permission signals you can inspect from outside the site.
Shows the deciding rule
If a URL is blocked, the report shows the exact Allow or Disallow rule that caused the result so you know what to change.
Pairs with technical SEO
Use this alongside the schema audit tool when you need to check both crawl access and structured data. If you are deciding between crawl blocking and search removal, start with robots.txt vs. noindex.
Common robots.txt mistakes
- Blocking the whole site with
Disallow: /after a redesign or staging launch. - Blocking CSS, JavaScript, or image paths that search engines need to understand the rendered page.
- Listing sitemap URLs that redirect, 404, or point to the wrong domain.
- Assuming robots.txt is the same as
noindex. It is not. Robots.txt controls crawling, whilenoindexcontrols indexing instructions on crawlable pages. See the plain-English decision guide.
Robots.txt checker FAQ
What does this robots.txt checker test?
It fetches the site's robots.txt file, parses the crawler rules, and tests your URL against the crawler you pick. The report names the exact Allow or Disallow line that decided the result.
Does robots.txt control whether a page is indexed?
No. Robots.txt controls crawl access, not indexing. A blocked URL can still appear in search if Google finds links to it, but Google cannot crawl the content, so the result often shows a bare URL with no description.
SEO workflow
Use the robots.txt checker before you diagnose indexing or content quality
Robots.txt is a crawl permission signal. If a page is blocked from crawling, every downstream SEO question gets fuzzy because search engines may not be able to fetch the page, read noindex tags, see canonicals, or evaluate the content.
-
Test the exact URL
Check the URL that matters, not just the homepage, because path-level rules can block service pages, resources, or folders selectively.
-
Read the matching rule
Use the allow or disallow rule shown by the tool to decide whether the block is intentional, stale, or accidentally inherited from staging.
-
Move to indexability
If crawling is allowed, check status codes, noindex, canonical tags, and sitemap consistency next.
