Robots.txt & Sitemap.xml Generator

What do robots.txt and sitemap.xml actually do?

robots.txt is a plain text file at your site's root that tells search engine crawlers which parts of your site they're allowed or not allowed to access. It's a request, not a security measure — well-behaved crawlers like Googlebot respect it, but it doesn't prevent a page from being indexed if other pages link to it, and it should never be relied on to hide sensitive content.

sitemap.xml is the opposite: a list of URLs you want search engines to know about and crawl, optionally with metadata like how recently each page changed. It doesn't guarantee indexing, but it helps search engines discover pages faster, especially on large or newly-launched sites.

Common robots.txt mistakes to avoid

• Accidentally blocking your entire site with Disallow: / under User-agent: *
• Blocking CSS or JS files search engines need to render your pages properly
• Using robots.txt to try to hide sensitive pages — use noindex tags or proper authentication instead
• Forgetting to update the sitemap URL if you migrate domains

Frequently Asked Questions (FAQ)

Q. Do I need both files?

A. Not strictly. Many sites run fine with just a sitemap and no custom robots.txt (search engines will crawl everything by default). robots.txt becomes useful once you need to restrict specific sections, like admin areas or duplicate filtered pages.

Q. Where does robots.txt need to live?

A. Exactly at your domain root — www.example.com/robots.txt. It won't be recognized anywhere else, including subfolders.

Q. Will blocking a page in robots.txt remove it from Google's index?

A. Not necessarily. If other sites link to a blocked page, Google can still index the URL without crawling its content. To fully remove a page from search results, use a noindex meta tag instead (on a page that robots.txt does NOT block, so Google can actually see the noindex instruction).
