Robots.txt Generator — background
Robots.txt tells search engine crawlers which pages to skip. The Robots Exclusion Protocol is a convention — search engines respect it, but it is not enforced. Never use robots.txt to hide sensitive content — use authentication instead, as the file is publicly readable. Furthermore, reference your sitemap in robots.txt to help crawlers discover it.
What is Robots.txt?
Common configurations: block AI crawlers (User-agent: GPTBot, User-agent: CCBot); block staging (Disallow: /); allow selective indexing. Use the meta robots tag (noindex) in HTML for more reliable indexing control — robots.txt only controls crawling, not indexing. Furthermore, Google Search Console provides robots.txt testing and crawl error reporting.
