About the Robots.txt Generator
The Robots Exclusion Protocol is a small but important agreement between a website and automated crawlers. A plain-text file named robots.txt tells cooperative robots which URL paths they may request and which paths they should leave alone. Search engines read it before crawling, so a carefully written file can reduce unnecessary requests, protect server resources, and make your preferred site structure clearer. This generator turns practical access choices into valid directives you can inspect before placing the file online.
Robots.txt is not a security wall and it is not an access-control system. It does not hide a URL from a person who already knows it, and a malicious scraper may ignore it. It is best used to guide well-behaved search crawlers away from admin screens, staging folders, internal reports, duplicate query paths, and other areas that do not belong in a crawl queue. Public pages that should appear in search should normally remain accessible and should not be blocked by a broad rule.
Crawlers scan links, sitemaps, redirects, and other signals over time. When a site is large or its hosting resources are limited, crawl guidance can help search engines spend more of their request budget on useful pages. The optional sitemap line gives a crawler a direct discovery hint, while specific user-agent blocks let you make a separate choice for AI training bots and search engine bots.
Key Use Cases
Manage crawl budget
Reduce repeated visits to filters, internal search pages, calendars, and duplicate URL variations so important content receives clearer crawl attention.
Control AI crawlers
Declare whether named AI agents such as GPTBot, ClaudeBot, Bytespider, CCBot, or PerplexityBot may request your content.
Hide staging paths from crawls
List folders such as /staging/, /admin/, or /private/ when they should not be part of normal discovery.
Declare your sitemap
Add an absolute sitemap URL so search crawlers can find the canonical list of pages on a static host.
How to Use This Tool
- Choose whether the default group of bots should be allowed or blocked. Use named toggles when a bot policy needs to differ from the global setting.
- List one or more paths to disallow. Separate paths with commas and begin them with a slash; use folders rather than accidentally blocking your entire site.
- Add a complete sitemap URL and review the generated code. Copy it to your clipboard or download the file directly from this page.
- Upload the file as
/robots.txtat the root of the public domain, then test the live response and submit the URL in the relevant webmaster tools.
Technical Example
For example, a publisher may want Googlebot and Bingbot to crawl public content while asking named AI scrapers to stay away from the site. The resulting file can look like this:
User-agent: GPTBot Disallow: / User-agent: ClaudeBot Disallow: / User-agent: Googlebot Disallow: User-agent: Bingbot Disallow: User-agent: * Disallow: /admin/ Disallow: /private/ Sitemap: https://example.com/sitemap.xml
Keep in mind that blank Disallow: lines allow the selected bot, while Disallow: / blocks every path for that user agent. Test carefully when rules overlap because a crawler’s interpretation can depend on its implementation.
Frequently Asked Questions
Does robots.txt hide pages from users?
No. It is public and advisory. Use authentication, authorization, or server rules for confidential information.
Where should I upload robots.txt?
Place it at the root of the exact host, such as https://example.com/robots.txt. A file inside a subfolder will not control the whole domain.
How long does Google take to update robots.txt rules?
Google may recrawl the file quickly, but crawl behavior and cached interpretations can take time. Test the live file and allow a reasonable propagation period.
Should I block all AI bots?
That is a publisher decision. Review each bot’s policies, your licensing goals, and the value of referral traffic before choosing.
Important Limitations
Rules only guide compliant crawlers and cannot replace a secure server configuration. Avoid blocking CSS, JavaScript, or image assets that search engines need to understand a page. A robots.txt rule also does not guarantee removal of an already indexed URL; use noindex directives where appropriate and ensure the page can still be crawled when removal needs to be observed. Review this file whenever your folder structure, sitemap, privacy policy, or crawler preferences change.
