I've checked the keywords list on the Google Webmaster Tools account for my website (which is a message board), and I noticed that the top keywords are things such as topic and forum. I'm guessing that is because those are the words which appear the most within the homepage.The question is, will this impact search results? I'm guessing yes. If so, can this be solved, and how? I already searched on Google and on SEO forums without any luck. (When it comes to SEO, most info looks like bogus to me. I hope I'm wrong, but meanwhile I'll ask here since it seems a reliable place.) 
How do keywords in Google Webmaster Tools affect search results?
