robots.txt Generator
Choose your crawl rules
A robots.txt file tells search engines which parts of your site they may crawl. Getting it right protects private areas and steers bots toward the pages that matter.
Copy your robots.txt
Pick which user-agents to allow or disallow, add your sitemap URL, and the tool builds a valid robots.txt for you to drop into your site root.

What Is a Robots.txt Generator?
A Robots.txt Generator creates a correctly structured robots.txt file from simple crawl-control settings. The file tells compliant search engine crawlers which areas of a website they may or may not request. It is mainly used to manage crawler traffic and prevent unnecessary crawling of duplicate, filtered, administrative, or low-value URL patterns.
Robots.txt controls crawling, not indexing or access security. A blocked URL may still appear in search results if search engines discover it through other links. Pages that must remain private should be protected with authentication, while pages that should not appear in search should use an appropriate noindex method and remain crawlable so the directive can be read.
How to Generate a Robots.txt File
Select the user-agents to which the rules should apply, then define the paths you want to allow or disallow. You can also add the complete URL of your XML sitemap. The tool combines these selections and generates a ready-to-copy robots.txt file directly in your browser.
The User-agent directive identifies the crawler covered by a rule group. An asterisk applies the group to all compliant crawlers, while a named user-agent targets a specific bot. Disallow identifies paths that should not be crawled, and Allow can permit a more specific path within a broader blocked section.
The optional Sitemap directive points crawlers to the sitemap location. It should contain a complete URL, such as https://example.com/sitemap.xml.
Where Should Robots.txt Be Placed?
The generated file must be named robots.txt and published at the root of the relevant hostname. For example, rules for https://www.example.com/ must be available at https://www.example.com/robots.txt. A file placed in a subdirectory does not control the whole site.
Rules are specific to the protocol, hostname and port where the file is hosted. Separate subdomains may therefore require their own robots.txt files.
Review Rules Before Publishing
A small mistake can unintentionally block important pages, CSS, JavaScript, images or an entire website from crawling. Review every path carefully and test important URLs after publishing. Avoid blocking resources that search engines need to render and understand your pages.
The generator simplifies the file structure, but the selected rules still determine the result. Update robots.txt whenever the website architecture, CMS, filtered navigation, test environment or sitemap location changes. All generation takes place locally in the browser, so the entered rules are not uploaded to a remote server.
