Construct error-free robots.txt files to manage search engine crawl budgets and direct web crawlers. Easily configure User-Agent directives, Allow/Disallow paths, and XML Sitemap declarations.
Create crawler groups, generate the final file, then copy or download it.
# Click "Add Group" then "Generate" to create your robots.txt
✅ Use root-relative paths: /admin/
✅ Sitemap needs full URL: https://example.com/sitemap.xml
✅ Use / to block all crawling
✅ Add multiple groups for different bots
The robots.txt file is a simple text file placed in your website's root directory. It acts as an instructions sheet for search spiders, telling them which sections they can crawl. Our Robots.txt Generator helps you create clean, error-free rules to optimize crawl budget.
Robots.txt uses User-Agent declarations to target specific crawlers (like Googlebot or Bingbot) or all crawlers using a wildcard (*). Allow and Disallow rules specify paths that bots are permitted or blocked from crawling. For example, disallowing "/admin/" protects internal admin directories from crawler traffic.
Search engines allocate a limited "crawl budget" to each website, which is the number of pages a bot will crawl during a visit. If spiders waste this budget crawling duplicate pages, query parameters, or search forms, they may miss your new content. Block unimportant directories in robots.txt to focus their attention.
Including a Sitemap declaration at the bottom of your robots.txt file is a standard SEO best practice. It provides crawlers with a direct path to your XML sitemap upon their first arrival on your domain, accelerating the discovery and indexation of your pages.
The robots.txt file must be uploaded to the root directory of your domain (e.g. crawlio.tech/robots.txt). If placed in a subdirectory, crawlers will not find it.
No. Robots.txt only blocks crawling (access). If other sites link to your disallowed page, Google can still index it without reading its content. To prevent indexing, use a "noindex" meta tag.
The asterisk * acts as a wildcard, matching any sequence of characters. It is commonly used to target all user-agents or apply rules to pattern-based path matches.
You can use Google Search Console's Robots.txt Tester tool to enter URLs and check if they are correctly allowed or blocked by your rules.
