Frequently Asked Questions

What is a Robots.txt Tester?

A Robots.txt Tester is a tool that helps you analyze and validate your robots.txt file to ensure it’s correctly configured. It checks for syntax errors, crawl permissions, and whether specific URLs are blocked or allowed for search engine bots.

Why is testing my robots.txt file important?

Testing your robots.txt file is essential to avoid accidentally blocking search engines from crawling important pages. A small mistake in the file can lead to reduced visibility in search results, affecting your site’s SEO.

Can I check if a specific URL is blocked by robots.txt?

Yes! Our Robots.txt Tester allows you to enter any URL and select a user-agent (like Googlebot) to instantly see if it’s allowed or blocked based on your robots.txt rules.

What does a “Disallow” or “Allow” rule mean in robots.txt?

“Disallow” prevents bots from crawling a specific path, while “Allow” explicitly lets them crawl it. Our tester tool displays these rules clearly so you can understand how different bots are being guided.

Is it safe to use this Robots.txt Tester tool?

Absolutely. Our tool only fetches and tests publicly available information from your robots.txt file or user input. No data is stored or shared. It’s safe, private, and free to use.
