Dolphin and SEO keywords

It's been a while since I did any SEO.  However, I believe you can put the pages you do NOT want searched in the robot.txt file on your site.  Not certain on this, just going off memory.

You cannot "remove" keywords from your site especially when they are such a prominent part of the site itself. What you need to do is focus on adding content that is relevant to your keywords and contains the keywords that you want to rank well for. If you want more specifics, let me know but if it were me, I would focus on keyword rich (1 to 2 percent keyword density, no more per article) for the blog and articles sections of your site as well as making sure blog titles, forum titles and article titles using your keywords abound on your site as well.

Hope it helps
