Search optimization and the things to learn
Search engine optimization professionals keep on top of all the hottest developments in Seo. This is essential because search engines change their algorithms constantly. A major search engine, like Google, will decide that, say, six percent is the ideal keyword density for a web page, and everyone optimizes their pages for six percent density; then Google realizes too many junk pages are making it through the filter, and lowers the optimum keyword density to four percent. Webmasters who leave their pages at six percent may find that their site has fallen behind, and perhaps has been penalized so heavily that it is now considered spam. Most webmasters are too busy handling content updates and managing new features to watch what search engines are up to.
