OK, I've been looking at this issue and what I have found is that if I have the same identical links in a very simple HTML page, then they are indexed, no problem. If they are in a more complex page, then they are skipped.
Here is the page
http://www.proofpoint.com/news/pressreleases.php
The pages that go to pressdetail.php are not indexed.
Any ideas?
Thanks.
