Free Online Robots.txt Generator
Your robots.txt file is one of the first things search engine crawlers read when they visit your site. It tells Google, Bing, and other bots which pages they can crawl and which ones they should skip. A misconfigured robots.txt can accidentally block your entire site from being indexed — or waste your crawl budget on pages that do not matter. Our free robots.txt generator helps you create a valid, well-structured file in seconds.
Just set your rules using the simple form, and the tool generates properly formatted robots.txt output that you can download or copy directly to your site's root directory.
How to Use the Robots.txt Generator
Select the user agent (or use * for all crawlers). Add allow and disallow rules for the paths you want to control. Optionally include your sitemap URL so crawlers can discover it automatically. The tool generates the robots.txt content in real time. Copy the output and save it as a file named robots.txt in the root directory of your website.
Why You Need a Robots.txt File
- SEO professionals manage crawl budget by blocking low-value pages like admin panels and search result pages.
- Web developers prevent search engines from indexing staging environments and development servers.
- E-commerce sites block duplicate product pages, filtered results, and internal search pages.
- Content sites guide crawlers to important sections while blocking draft or archive pages.

Best Practices for Robots.txt
Never use robots.txt to hide sensitive pages — it is publicly accessible, so anyone can read it. Use it for crawl management, not security. Always include your sitemap URL in the file. Test your robots.txt in Google Search Console before deploying to make sure you are not accidentally blocking important pages. Remember that robots.txt is a directive, not a guarantee — well-behaved bots follow it, but malicious ones can ignore it.
Frequently Asked Questions
Where should robots.txt be placed?
The robots.txt file must be in the root directory of your domain. For example, it should be accessible at https://example.com/robots.txt. If it is in a subdirectory, crawlers will not find it.
Does robots.txt prevent pages from being indexed?
Not exactly. Robots.txt prevents crawling, but if other pages link to a blocked URL, Google may still index it (without content). To prevent indexing entirely, use a "noindex" meta tag or X-Robots-Tag HTTP header instead.
What does "User-agent: *" mean?
The asterisk (*) is a wildcard that applies the rules to all web crawlers — Googlebot, Bingbot, and any other bot that respects robots.txt. You can also create rules for specific bots by naming them, like "User-agent: Googlebot."
