About Robots.txt Generator
Everything you need to know about creating and managing robots.txt files for your website.
What Is a Robots.txt File?
A robots.txt file is a plain text file placed in the root of a website that tells web crawlers (like Googlebot, Bingbot) which URLs they can and cannot access. It follows the Robots Exclusion Standard and is the first file crawlers check when they visit a site.
How the Robots.txt Generator Works
Our generator provides an intuitive checklist-driven interface. Select the crawler (user-agent), choose from common directives like Allow, Disallow, Crawl-Delay, and Sitemap, and specify the paths. The live preview updates instantly, and you can copy or download the final file - no server-side processing required.
Why Use a Generator Instead of Writing Manually?
Manual robots.txt editing is error-prone - a single typo in a path or a misplaced directive can accidentally block important pages from search engines. A visual generator eliminates syntax errors, enforces best practices, and provides guidance on modern SEO patterns like AI bot directives and sitemap submissions.
Tips for an Effective Robots.txt
Always include a Sitemap directive pointing to your XML sitemap. Use Crawl-Delay for shared hosting or rate-limited servers. Be specific with paths - broad Disallow rules can unintentionally hide content. Test your robots.txt using Google Search Console's robots.txt Tester before deploying to production.

Frequently Asked Questions
Common questions about robots.txt files and how to use our generator.
A robots.txt file tells search engine crawlers which parts of your website they are allowed to access. It helps prevent crawlers from wasting bandwidth on admin pages, duplicate content, or staging environments. While not strictly required, it is considered an SEO best practice and is the first file most crawlers check when visiting your site.
The robots.txt file must be placed in the root directory of your website - for example, https://example.com/robots.txt. It cannot be placed in subdirectories. Most web hosts and CMS platforms (WordPress, Shopify, etc.) provide a way to upload or edit this file from the file manager or admin panel.
Disallow tells crawlers they should not access the specified URL path. Allow overrides a Disallow rule for a more specific path, which is useful when you want to block a directory but allow a specific file within it. Both directives follow the longest-match rule: the most specific path wins when there are conflicting rules.
The User-agent directive specifies which crawler the following rules apply to. For example, User-agent: Googlebot applies the subsequent rules only to Google's crawler. Use a wildcard (*) to target all crawlers. You can define multiple user-agent blocks to set different rules for different crawlers.
Many website owners choose to block AI training crawlers (like GPTBot, CCBot, Claude-Web) to prevent their content from being used to train large language models without attribution. Our generator includes dedicated options for these crawlers so you can make an informed decision about AI bot access.
Crawl-Delay tells crawlers to wait a specified number of seconds between requests. It is useful for shared hosting plans, rate-limited servers, or sites that experience performance issues during crawler activity. The directive is supported by Bing, Yandex, and some smaller crawlers, but Google ignores it in favour of its own crawl rate settings in Search Console.
Add a Sitemap directive at the bottom of your robots.txt file: Sitemap: https://example.com/sitemap.xml. You can include multiple Sitemap directives for different sitemap files. This helps crawlers discover your sitemap immediately without needing to submit it through search engine webmaster tools.
Robots.txt is a publicly accessible file - anyone can view it by visiting /robots.txt on your domain. Do not use it to hide sensitive pages (like admin panels) since it acts as a hint, not a security measure. Malicious actors may use robots.txt to discover hidden paths. For real security, use authentication and server-side access controls.
Google Search Console provides a built-in robots.txt Tester that lets you validate your file and test how Googlebot would interpret specific URLs. You can also use our related Robots.txt Validator tool on this site for comprehensive syntax and best-practice checking before deploying to production.
