Small business website Where to start
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. Webmasters with a little more technical skill use "doorway pages" to show specially optimized pages to search engines, instead of showing them the less optimized pages that human viewers see. Search engines strongly penalize sites that show them doorway pages.
