Ranking tools, a quick primer
To avoid being penalized for this common Seo mistake, give your pages natural sounding titles and do not put any text on the page that does not pertain to the page's topic. A more sophisticated variant of keyword stuffing is spreading keywords through the page's body text instead of lumping them together in a single block. Search engines scan for this SEO trick by calculating each page's keyword density and penalizing pages whose density falls above a target range. The target range has been falling lower and lower for the past several years. To avoid penalties for having a poor keyword density, keep track of the currently desirable density via webmaster forums, and rewrite pages if their keyword density is too high.
