What is a robots.txt file?

A robots.txt file tells search engine crawlers which pages or files they can or cannot request from your site. It helps control indexing and optimize SEO.

Do I need a sitemap in robots.txt?

It’s highly recommended to include your sitemap in robots.txt. This helps search engines discover and crawl your pages efficiently.

Can I block specific bots with robots.txt?

Yes. You can target specific user-agents such as Googlebot, Bingbot, or others and allow/disallow them accordingly.

Is robots.txt mandatory for SEO?

No. It’s optional, but strongly recommended for managing crawl budget, blocking private areas, and improving SEO structure.

# robots.txt generated by Toolzium

User-agent: *
Disallow:

Sitemap: https://example.com/sitemap.xml

Tips

Use wildcards (*) and end-anchors ($) for patterns. Keep sensitive content off the web; robots.txt is public.

robots.txt

Disallow prevents compliant bots from crawling; it doesn’t hide URLs.
Place robots.txt at the root: https://your-domain.com/robots.txt.
Add Sitemap: lines for each sitemap URL (XML index or individual files).
Prefer Allow: exceptions before broad Disallow patterns for clarity.
Test with Google Search Console’s robots tester where available.
