Can you please verify my robots.txt for wordpress

The file robots.txt doesn’t exclude all the search engines to crawl your site… Most search engines crawl the hole site without taking the robots.txt file in consideration.

I think that the best way is to use meta tags in the theme of the blogs.

Use the next meta tags for post and categories template files:

<meta name="robots" content="index, follow" /> 
<meta name="googlebot" content="index, follow" />

Use this meta tags for the rest of the template files

<meta name="robots" content="noindex, nofollow, noarchive" />
<meta name="googlebot" content="noindex, nofollow, noarchive" />
