Does robots.txt actually prevent Google from indexing a page?

Disallowing a URL in robots.txt prevents Googlebot from crawling it, but if other sites link to that URL, Google may still index it without visiting the page. To truly prevent indexing, use a noindex meta tag or X-Robots-Tag HTTP header.

What is the difference between Disallow and noindex?

Disallow in robots.txt blocks the crawler from fetching the page at all. noindex is a directive in the page itself (or HTTP header) telling crawlers not to index the page but still allowing them to crawl it.

How do I block AI scrapers like GPTBot?

Add a specific rule for AI crawlers: User-agent: GPTBot, followed by Disallow: /. Other AI bots to consider blocking: CCBot, anthropic-ai, Google-Extended, and PerplexityBot.

What is Robots.txt Generator?

A robots.txt file tells search engine crawlers which pages of your site should not be indexed or visited. It's the standard mechanism for blocking crawlers from admin pages, duplicate content, staging environments, or large binary files. DailyDevTools' Robots.txt Generator provides a visual builder to create rules for specific crawlers (Googlebot, Bingbot, GPTBot, etc.) without memorizing the syntax.

How to use Robots.txt Generator

2Add a Sitemap directive pointing to your sitemap.xml URL
3Set a Crawl-delay if your server has limited resources and needs to throttle crawlers
4Preview the generated robots.txt and click Copy or Download to save it
