Robots.txt Generator for Crawler Rules
Draft robots.txt rules for public websites, staging sites, blocked paths, sitemap directives, preferred hosts, and common AI crawler controls with browser-side processing.
Try a common robots.txt scenario
Enter one path per line. Paths are normalized with a leading slash.
Robots note
robots.txt is a crawl directive, not access control. Keep private content behind authentication and verify the deployed file line by line before submitting it to search engines.
Mode

Off
Robots.txt gives crawlers instructions about which paths they should or should not crawl.
It should live at the root of your domain.
Public path list
Block only paths that should not be crawled, such as admin, API, dashboard, or private folders.
Real sitemap URL
Use the production sitemap URL that crawlers should discover from robots.txt.
User-agent: * Disallow: /admin
Most robots.txt files use User-agent, Allow, Disallow, and Sitemap lines. Specific crawler policies can be added in separate blocks.
Robots.txt is a public instruction file. It should not be used to protect secrets, private documents, admin data, or sensitive URLs.
Use authentication and authorization for private content, and use noindex or removal tools for index cleanup workflows.
Public site launch
Allow crawling, block admin or API paths, and include the sitemap URL.
Staging environment
Create a temporary block-all draft for test domains that should not be crawled.
AI crawler policy
Add common crawler-specific blocks for review before publishing.
SEO QA
Draft rules before checking them with a crawler or search console tool.
Example
A public site can allow root crawling, disallow /admin and /api, and include a sitemap directive.
Assumption
The generated file will be reviewed and placed at the domain root as /robots.txt.
Limitation
Robots.txt is advisory for compliant crawlers and does not secure private content.
Can robots.txt block Google from indexing a page?
It can block crawling, but it is not a reliable noindex mechanism. Use noindex for index control.
Should I include a sitemap line?
Usually yes. A Sitemap directive helps crawlers discover your XML sitemap location.
Can I block all crawlers on staging?
Yes, but also use authentication. Robots.txt alone is not security.
Does this validate live robots.txt?
No. It generates a local draft. Use a crawler or search console tool to validate deployed files.
Suggested workflow
Crawl control QA path
Draft crawler rules, check sitemap coverage, and add page-level index controls when needed.
