I recently set up a forum using PHPBB as my CMS system. In order to make it SEO-friendly, I used PHPBB3 SEO. It looks great. All my urls are in section/topic.html format and I use robot.txt file to exclude all php?messyvariables. And I even tried to type in some dulplicate links, they are either redirected or excluded from robot.txt. BUT after months since I launched the forum, I do a search on google, I still see the link atat the last page with the link says: repeat the search with the omitted results included. AND most of my links are omitted.
My website url is: http://www.ebooks.highub.com/
The keyword search I did was: http://www.google.com/search?hl=en&rls=com.microsoft%3Aen-US&q=highub.com
But to my surprise, when I did a search on http://www.google.com/search?q=site:www.ebooks.highub.com&hl=en, no urls are omitted.
Can someone explain the reason why? Thanks in advance!
