The robots.txt file provides directives to search engine crawlers, letting you control which parts of your site can be crawled. By specifying “Disallow” rules, you can prevent crawlers from visiting certain pages or directories — useful for avoiding duplicate or sensitive content in search results.
Including a Sitemap URL also helps search engines discover and index your site’s pages more efficiently. In short, a well-structured robots.txt is key to a robust SEO strategy, ensuring search engines crawl and rank your site accurately.
