What is a robots.txt file?
A robots.txt file is a text file that provides instructions to search engine crawlers on which pages or sections of a website should or shouldn't be crawled.
Why is validating robots.txt important?
An incorrect robots.txt file can unintentionally block search engines from indexing important pages, harming your SEO and visibility.
What does "User-agent" mean in robots.txt?
User-agent specifies which search engine crawlers (e.g., Googlebot, Bingbot) the rules apply to. You can define different rules for different bots, allowing you to control how various search engines access your site.
Can I use robots.txt to hide pages from search results?
No. Robots.txt only controls crawling, not indexing. To prevent indexing, use a noindex directive in your meta tags or HTTP headers.
What happens if my robots.txt file has errors?
Errors in robots.txt can lead to search engines ignoring the file or crawling restricted areas. Our tool helps you identify and fix these issues quickly.
What does a "Blocked" status mean in the report?
A "Blocked" status indicates that certain pages or content are restricted from being crawled by search engine bots. If important content is blocked, it could impact indexing and search visibility.
How can I unblock important pages in my robots.txt file?
If important pages are blocked, you should update your robots.txt file by removing or adjusting the Disallow directive for those pages. Our tester provides guidance on the rules to be updated.
What is the difference between "Disallow" and "Allow" in robots.txt?
This Disallow directive prevents search engine bots from crawling certain pages or directories, whereas Allow explicitly permits access to specified sections, even within a restricted area.
How can I save or download my robots.txt file after testing?
Once you test your robots.txt file, you can either download the updated version or copy the necessary modifications directly from the editor window.
