Robots.txt Generator
Generate structured robots.txt configurations to declare indexation guidelines and crawler bot directories rules.
How to Use

- 2 Specify crawl-delay parameters if necessary.
- 3 Check any boxes to block specific search and AI bots.
- 4 Add custom directories (Disallow or Allow) to the rule table.
- 5 Paste your XML Sitemap URL and click 'Generate robots.txt'.
Key Features

- ClaudeBot)
- Standard delay metrics configurator
- Interactive Allow/Disallow path rules registry
- One-click Copy and TXT file download
Detailed Overview & How It Works
The Robots.txt Generator is designed to optimize your website search visibility and bot crawlability directly from your browser. By compiling search engine configurations (robots.txt, XML sitemaps, and llms.txt context profiles) client-side, the utility ensures formatting accuracy and adherence to standards.
The Robots Exclusion Protocol Explained
The robots.txt file is the cornerstone of the Robots Exclusion Protocol (REP), a standard utilized by search engines since 1994. Located at the root of a website (e.g. https://example.com/robots.txt), it instructs search engine crawlers which parts of the site they are disallowed from visiting. These rules are advisory but widely followed by reputable web services.
Blocking AI Training Scrapers
In the age of generative AI, many website owners want to prevent their content from being consumed to train LLM models without permission. Standard crawlers like OpenAI's GPTBot and Anthropic's ClaudeBot respect robots.txt exclusion rules. By declaring User-agent: GPTBot followed by Disallow: /, you block these scrapers from accessing your website, protecting your proprietary content and intellectual property.
Wildcards and Advanced Robots Syntax
Robots.txt supports wildcards (*) and line end markers ($) to write patterns. For example, to block search engines from crawling PDF documents on your site, you can add Disallow: /*.pdf$. This tells search crawlers to ignore any URL path ending with the .pdf extension.
Standard Directives: User-Agent, Allow, Disallow, and Sitemap
Every rule block in a robots.txt file begins with a User-agent: declaration, defining which crawler the rule applies to (e.g. * for all, or Googlebot). Following that, you use Disallow: to list excluded folders and Allow: to white-list exceptions inside disallowed directories. Finally, the Sitemap: directive is declared globally (outside User-agent blocks) to inform search engines of your sitemap location.
Testing and Validating Your Robots.txt Configuration
Before uploading your robots.txt file to your live web server, it is highly recommended to run it through testing tools. Google's Search Console provides a dedicated "Robots Testing Tool" under the Crawl menu. You can paste your code, input test URLs (like admin panels or document paths), and see if the crawler correctly blocks or allows them according to your custom directives.
Search Crawler and AI Bot Integration
Modern SEO requires managing access policies not just for traditional search engines (like Google and Bing), but also for AI scrapers (like GPTBot and ClaudeBot). This utility generates clean, properly formatted rules to secure and optimize your site discoverability.
Local-Only SEO Data Promise
Privacy Notice: Your website URLs, robots rules, and scraper guidelines are processed 100% locally in your web browser. No site maps or data indexes are saved, uploaded, or transmitted online, guaranteeing complete confidentiality.
Pro Tips & Best Practices for SEO Tools
- Verify Sitemap Protocols: Ensure all URLs in your XML sitemaps include correct protocols (http:// or https://) and match your primary domain.
- Host at Website Root: Files like robots.txt and llms.txt must be placed directly in your website's root public_html directory (e.g. /robots.txt) for crawlers to find them.
- Use Lowercase Path Directives: Crawler folders are case-sensitive. Verify that directory exclusions in robots.txt match the exact casing of your web servers.
- Test Sitemap URL Links: Before submitting your sitemap, copy and test a few URLs in your browser to confirm they resolve without errors (e.g. 404 or 500).
Frequently Asked Questions (FAQs)
Q What is Robots.txt used for?
It tells search engine crawlers which pages or folders they can or cannot request from your site. This optimizes search performance and helps prevent resource overloading.
Q How do I block AI scrapers?
Our generator includes checkboxes to specifically add Disallow commands for common AI bots such as GPTBot (OpenAI) and ClaudeBot (Anthropic).
