What is robots.txt?
robots.txt is a plain text file at the root of your website (e.g., https://example.com/robots.txt) that follows the Robots Exclusion Protocol. It tells search engine crawlers which URLs they are allowed to access:
User-agent: *
Allow: /
Disallow: /admin/Sitemap: https://example.com/sitemap.xml ```
Key concepts:
- User-agent: Which crawler the rules apply to (* means all)
- Allow: Explicitly permit crawling of a URL path
- Disallow: Block crawling of a URL path
- Sitemap: Tell crawlers where to find your sitemap
robots.txt best practices for SEO
Do block: - Admin and login pages (/admin/, /login/) - API endpoints (/api/) - Internal search results pages (/search?q=) - User account pages (/account/, /profile/) - Cart and checkout pages (/cart/, /checkout/) - Staging or development environments
Do not block: - CSS and JavaScript files (Google needs these to render your pages) - Images (unless you want them excluded from Google Images) - Your homepage or main content pages - Pages you want to appear in search results
Important: robots.txt blocks crawling, not indexing. A page blocked by robots.txt can still appear in search results if other sites link to it.
Common robots.txt mistakes
Blocking the entire site: The most dangerous mistake.
``
# WRONG - blocks everything!
User-agent: *
Disallow: /
``
Blocking CSS/JS: This prevents Google from rendering your page correctly.
``
# WRONG - blocks rendering resources
Disallow: /css/
Disallow: /js/
``
Not including sitemap: Always reference your sitemap in robots.txt.
Using noindex in robots.txt: The noindex directive in robots.txt is not supported by Google. Use the noindex meta tag instead.
Forgetting trailing slashes: Disallow: /admin blocks everything starting with /admin (including /administrator). Use Disallow: /admin/ to only block the /admin/ directory.

Frequently Asked Questions
Does every website need a robots.txt file?
It is recommended but not required. Without a robots.txt, search engines assume they can crawl everything. For most sites, a basic robots.txt with a Sitemap directive is sufficient.
Can robots.txt prevent a page from appearing in Google?
Not directly. robots.txt blocks crawling but not indexing. If other sites link to a blocked page, Google may still show it in results (without a snippet). Use the noindex meta tag to prevent indexing.
How do I test my robots.txt?
Use Google Search Console's robots.txt Tester (under Settings > robots.txt). You can test any URL against your rules to see if it would be blocked.
How often does Google check robots.txt?
Google caches your robots.txt and rechecks it periodically (usually every 24 hours). Changes are not immediate.
