robots txt Generator

A robots.txt file sits at your site root and is the first thing a search-engine crawler checks when it arrives. It tells crawlers which parts of your site they may and may not request — useful for keeping bots out of admin, cart, staging or search-results pages, and for managing crawl budget on large sites. It’s a small file with outsized consequences: get it right and crawlers focus on what matters; get it wrong and you can hide your whole site from Google.

That last point is the single most common robots.txt disaster: a stray Disallow: / under User-agent: * blocks every crawler from your entire site — usually left behind from a staging setup. This tool warns you before you export that rule. Just as important is a misconception worth clearing up: robots.txt controls crawling, not indexing. A page you block here can still appear in Google if other sites link to it — so to actually keep a page out of results, use a noindex meta tag and leave it crawlable, rather than blocking it in robots.txt.

One modern rule that trips people up: don’t block your CSS and JavaScript. Older guides told you to disallow theme and asset folders, but Google now needs to render your pages the way a visitor sees them — block those files and it can’t, which can hurt your rankings. A good robots.txt today leaves assets crawlable, blocks only what genuinely shouldn’t be crawled, and points to your sitemap. This tool builds exactly that, and everything runs in your browser with nothing uploaded.

When you’re done, upload the file to your site root — it only works at yoursite.com/robots.txt, never in a subfolder. Building out the rest of your technical setup? The XML Sitemap Generator and llms.txt Generator handle the other two root files crawlers look for.
