Meta Tag to Prevent Search Engine Bots | CSS-Tricks

 

To prevent all search bots from indexing a page:

<meta name="robots" content="noindex">

To prevent just Google:

<meta name="googlebot" content="noindex">

If you have control over it, you probably want to add nofollow to links that point to that page as well:

<a href="privatepage.html" rel="nofollow">Link to private page</a>

Theoretically that’s not needed for Google, which claims to drop all pages with noindex from their directory. But there are more search engines out there and it doesn’t hurt.
