What is robots.txt used for?

The robots.txt file tells search engine crawlers which parts of your site to crawl and which to skip. It is checked by Googlebot, Bingbot, and most other legitimate crawlers before they access your site. It controls crawl budget, prevents indexing of private areas, and can direct crawlers to your sitemap.

Does robots.txt prevent pages from being indexed?

No — it prevents crawling, not indexing. A Disallow rule stops crawlers from visiting a URL, but if other sites link to that URL, it can still appear in search results. To prevent indexing, use a noindex meta tag or X-Robots-Tag response header on the page itself.

What does Disallow: / mean?

Disallow: / blocks the crawler from accessing any page on the site. This is one of the most dangerous robots.txt entries because it can completely remove a site from search engine indexes. Only use this intentionally for staging sites or private applications.

Can I use robots.txt to block all crawlers except Google?

Yes. Add a User-agent: * block with Disallow: / to block all crawlers, then add a separate User-agent: Googlebot block with Allow: / to permit Googlebot. This is a legitimate strategy for sites that only want Google to crawl them.

Where should robots.txt be placed?

robots.txt must be at the root of your domain: https://yourdomain.com/robots.txt. It only applies to the domain it is served from, not subdomains or subdirectories.

What is Robots Txt?

The Robots.txt Generator on AiTechWorlds creates a valid robots.txt file for your website with a simple visual form interface. The robots.txt file sits at your domain root and instructs search engine crawlers which pages or sections of your site to crawl or skip. Getting it wrong can accidentally block Google from crawling your entire site (a common and disastrous mistake), allow crawlers to index private pages, or waste crawl budget on unimportant pages. This tool provides inputs for each User-agent, Allow rules, Disallow rules, crawl delay, and sitemap URL — then generates a correctly formatted, RFC 9309-compliant robots.txt. All generation runs in your browser with no server call. AiTechWorlds built this tool for site owners, SEO professionals, and developers who need a correct robots.txt without knowing its syntax by heart.
