Search engines don't pick up links/posts.

We have meta tags and the search engines pick up on these. But they are not picking up links on the main page, nor any post headings etc.

Does anyone know what the problem might be?

I used a server checker called the "SEO Consultants Check Server Headers Tool"
See here: http://www.seoconsultants.com/tools/headers.asp

Here are the results:

SEO Consultants Directory Check Server Headers - Single URI Results

Does that help?
