Frequently Asked Questions
Search engine crawlers default to assuming the entire site is allowed to be crawled - a missing robots.txt is not an error, but it also means you have no way to explicitly exclude specific paths from crawling.
Not reliably on its own - it only requests that crawlers not fetch the page; a page can still be indexed (using information from links elsewhere) even if crawling is blocked. Use a noindex meta tag for a genuine guarantee.
It instructs crawlers not to access anything on the entire site - this is occasionally left in place accidentally after a staging/development site goes live, silently blocking the whole site from being crawled.
Yes, it's standard and recommended practice to include a "Sitemap:" line pointing to your sitemap.xml location - this gives crawlers an easy, explicit way to discover it.
Yes - robots.txt supports separate rule blocks per "User-agent", so you can allow Googlebot broader access while restricting a different, less-trusted crawler, for example.
No - it's purely a crawling-behavior request that well-behaved bots choose to honor; it provides no actual access restriction or security, and should never be relied on to hide genuinely sensitive content.
