I would say to many banners…. needs some good content and if those are links to the left they do not work for me. try not to use same text color as the background and dont repete your keyword 100 times in a row your going to get penalized!
1.Take down alot of the banners i would say 3 at the most your site would be faster and look better.
2. Do not make the text color the same as the background instead write 350 words about your site use a keyword that gets some good hits but low compatition and matchs your sites topic Put it in your title, h1, bold, alt tag meta tag, a link, and tords the end of your content try not to over do the keyword in your content. then start trading links with your keyword in the achor text on other sites. and if you really want be clean USE css and xhtml for your sites code :hattip:
hope this helps… thanks
