I look at a lot of sites on a daily basis. There are a lot of common problems I see on sites. Some people may have tags set-up improperly or use tags that have no real purpose. I have compiled a list of the 5 top do-it-yourself SEO errors. It's safe to say that many do-it-yourselfers may have at least one of these errors on their sites. These should help you omit these often costly mistakes and pull you up in the ranks.
