Generate, validate, and test robots.txt files for search engine crawler control. Check which URLs are allowed or blocked for specific bots, and verify your configuration is correct.
robots.txt: Crawler Directives, Wildcards, and Crawl Budget Management
The robots.txt file is a plain-text file placed at a domain's root (e.g., https://example.com/robots.txt) that follows the Robots Exclusion Protocol. It contains directives for web crawlers: User-agent fields identify which bots the rules apply to (* for all crawlers, Googlebot for Google, bingbot for Bing), and Disallow/Allow fields specify URL patterns to block or permit crawling.
Robots.txt controls crawler access but does not prevent indexing of pages linked from other sites — a bot bypassing robots.txt could still index a disallowed page if the URL appears in external links. For true exclusion from search indexes, use noindex meta tags or X-Robots-Tag HTTP headers instead. Robots.txt is best used for crawl budget management: preventing crawlers from wasting time on duplicate content pages, faceted navigation, search result pages, and internal admin URLs that don't benefit from indexing.
Googlebots now support Extended Crawl Delay specifications and can handle path-prefix wildcards (* and $). The Sitemap directive in robots.txt informs crawlers where to find your sitemap XML, which helps them discover new content efficiently. Well-configured robots.txt files are a routine part of technical SEO maturity.
Block crawlers from staging and dev environments
Disallow all bots from non-production URLs to prevent accidental indexing of staging content.
Protect admin and authentication URLs
Block crawler access to /admin/, /login/, /dashboard/ and other paths that shouldn't appear in search results.
Prevent duplicate content indexing
Disallow faceted navigation parameters, print versions, and paginated search result pages that create duplicate content.
Test which URLs are blocked for specific bots
Verify that your existing robots.txt rules correctly allow or block specific URL patterns for Googlebot or other crawlers.
- 1
Generate or paste your robots.txt
Use the generator to build rules by selecting user-agents and entering URL patterns, or paste an existing robots.txt for validation.
- 2
Test specific URLs against your rules
Enter a URL and select a user-agent to check whether your rules allow or disallow crawling of that specific path.
- 3
Validate syntax and download
Review validation results for syntax errors, conflicting rules, or common misconfiguration patterns, then download the final file.
URL tester
Test any URL against your robots.txt rules for any user-agent to verify allow/disallow behavior before deploying.
Syntax validation
Detects common robots.txt syntax errors including incorrect wildcard usage, malformed User-agent declarations, and conflicting rules.
Common bot presets
Quick-select rules for Googlebot, Bingbot, GPTBot, CCBot, and other common crawlers from a preset library.
Sitemap directive generation
Adds the Sitemap: directive to your file pointing to your sitemap.xml, which helps all bots discover your content.
