Robots.txt Generator builds the file that tells search engine crawlers which parts of a site they can and can't access, without needing to remember the exact syntax.
What is a robots.txt file, and what does it actually do?
It's a plain text file placed at a site's root — like example.com/robots.txt — that gives compatible crawlers instructions about which URLs or paths they're requested to crawl or avoid. It provides crawling guidance, not access control: it can politely ask a well-behaved crawler to stay away from a path, but it shouldn't be relied on to keep genuinely private information out of search engines, since it doesn't prevent access, only requests that crawlers not visit.
Can robots.txt actually keep a page out of Google's search results?
Not reliably, and this is the single most common misunderstanding about it. Robots.txt controls crawling — whether a bot requests a URL — not indexing, which is a separate decision search engines make. If a page is already indexed, blocking it in robots.txt alone won't remove it from search results; you'd need a noindex directive on a page Google can still access instead. That's the real difference between the two: robots.txt tells crawlers where not to go, while a noindex tag tells search engines not to index a page they're still allowed to visit.
What do User-agent, Disallow and Allow actually mean, and can they block a whole folder or site?
User-agent identifies which crawler a rule applies to — an asterisk (*) applies it to every crawler, or you can name a specific one for different rules per bot. Disallow tells a crawler not to request matching URLs or paths, and Allow explicitly permits crawling of a path, useful when it's more specific than a broader Disallow covering the same area. Both a single folder and an entire website can be blocked with the right Disallow rule — which is exactly why an overly broad rule is worth testing carefully before publishing, since one mistake can accidentally block crawlers from an entire site.
Should you include your sitemap in robots.txt, and where does the file actually need to live?
Yes — a Sitemap directive pointing to the full sitemap URL makes it easier for crawlers to discover your sitemap automatically. The file itself has to sit at the root of the domain specifically, like https://example.com/robots.txt, since search engines only check that one standard location and won't find a robots.txt file placed anywhere else.
Does robots.txt actually improve SEO, and when should you block pages with it?
Not directly — its real value is managing crawl budget, keeping crawlers from wasting time on pages that don't need to be crawled, rather than boosting rankings. Only block pages when there's a clear crawling reason; blocking important pages can accidentally prevent search engines from accessing content they actually need to understand and rank your site.
Why does something this important run on such an informal set of rules?
Because for nearly 30 years, it genuinely wasn't an official standard at all — just a convention everyone agreed to follow. Dutch software engineer Martijn Koster proposed the Robots Exclusion Protocol in 1994 after a poorly-behaved early web crawler repeatedly hammered his server, and by June of that year it had already become the de facto standard: major crawlers of the era, including WebCrawler, Lycos and AltaVista, simply agreed to respect it voluntarily, with no governing body enforcing anything. That informal arrangement lasted for a genuinely surprising amount of the web's history — it wasn't until July 2019 that Google proposed formalizing it through the Internet Engineering Task Force, and the protocol only became an official internet standard, RFC 9309, in September 2022. In other words, one of the most widely respected rules on the entire internet ran for 28 years purely on good-faith cooperation before anyone bothered to make it official.
