A Robots.txt Generator creates the robots.txt file that instructs search engine crawlers which parts of your website they may or may not access. This small text file sits at your domain's root and acts as a gatekeeper: it can keep bots out of admin areas, staging sites, duplicate content and resource-draining pages, while welcoming them into the content you want indexed. Getting it right protects both your SEO and your server.
Poorly configured crawler rules cause real damage — accidentally blocking your entire site from search engines is one of the most common and painful SEO mistakes. This free tool generates correct robots.txt syntax through a simple form, so you never have to memorize directives or risk a typo that de-indexes your site. Whether you are launching a new site or cleaning up an old one, start with a valid robots.txt. It takes less than a minute to generate, yet it quietly protects your crawl budget, your server resources and your search visibility from the day your site goes live.
It must live at the root of your domain — for example, https://yoursite.com/robots.txt. Files placed in subfolders are ignored by crawlers. Most hosting control panels, including the StackCP file manager, let you upload it directly to the public_html or www root in seconds without touching FTP.
Never disallow your CSS, JavaScript or image files — Google needs them to render pages properly — and double-check that you are not blocking your entire site with "Disallow: /" applied to all user agents.
Not always. Blocked pages can still appear in results if other sites link to them, just without a description. For content that must stay private, use password protection or a noindex meta tag instead of relying on robots.txt alone. Remember that well-behaved crawlers obey robots.txt voluntarily — it is a request, not a security barrier, so never use it as your only protection for sensitive data.
Visit yourdomain.com/robots.txt in a browser to confirm it loads, then test it in Google Search Console's robots.txt tester, which shows exactly how Googlebot interprets each rule.
