robots.txt Generator
Build your site's robots.txt file: pick the user-agent, add Allow and Disallow rules, point to your sitemap and download the file ready to upload.
What a robots.txt file does
The robots.txt file lives at the root of your site (e.g. https://www.yoursite.com/robots.txt) and tells search engine crawlers which paths they may visit. The Disallow directive asks bots not to crawl a path, while Allow carves out an exception inside a blocked folder (say, you block /admin/ but allow /admin/public/). One important caveat: robots.txt controls crawling, not indexing โ a blocked page can still show up on Google if other sites link to it. To truly keep a page out of search results, use a noindex meta tag instead.
The rules most sites actually use
Almost every site blocks private areas such as /wp-admin/ or /admin/, shopping carts and internal search pages with query parameters, which only waste crawl budget. Adding a Sitemap: line with the full URL helps Google and Bing discover all your pages right away. Keep in mind that paths are case-sensitive, and that each block of rules applies to the user-agent declared above it: with * you address every bot at once.
