Frequently Asked
Questions
1. What is a robots.txt file?
A robots.txt file is a plain text file placed at the root of your website that tells search engine bots and other web crawlers which pages or sections they are allowed or not allowed to access. It follows the Robots Exclusion Protocol, a standard supported by all major search engines including Google, Bing, and Yandex.
2. Does robots.txt affect my Google rankings?
Robots.txt does not directly impact rankings, but it significantly affects how efficiently Googlebot crawls your site. Blocking unnecessary pages (like admin panels, duplicate content, or staging URLs) helps Google focus its crawl budget on your important pages — indirectly improving how quickly new content gets indexed.
3. Can I block AI crawlers like ChatGPT and Claude using robots.txt?
Yes. You can block AI training bots like GPTBot (OpenAI), Claude-Web (Anthropic), PerplexityBot, and Google-Extended (Gemini) using Disallow rules. Our tool includes a one-click “Block AI Crawlers” section to add all these rules instantly.
4. Will blocking a bot in robots.txt completely stop it?
Blocking a bot via robots.txt works for crawlers that respect the Robots Exclusion Protocol — all major search engines and legitimate AI bots do. However, malicious scrapers or poorly built bots may ignore the file entirely. For sensitive content, always use proper server-level authentication.
5. What is Crawl Delay and should I use it?
Crawl Delay tells a bot how many seconds to wait between requests. It can reduce server load on high-traffic sites. Note that Googlebot ignores this directive — use Google Search Console to manage Googlebot’s crawl rate instead. It is useful for Bingbot and other bots.
6. Where exactly do I upload the robots.txt file?
It must be placed at the root of your domain — https://yourdomain.com/robots.txt. Putting it in a subdirectory (like /blog/robots.txt) will not work. Search engines only check the root location.
7. Can I have multiple robots.txt files for subdomains?
Yes. Each subdomain needs its own robots.txt file at its root. For example, https://shop.yourdomain.com/robots.txt is separate from https://yourdomain.com/robots.txt and requires its own rules.
8. Is this Robots.txt Generator completely free?
Yes — 100% free, no sign-up, no account needed, no hidden charges. Generate and download as many robots.txt files as you need at no cost.
