Some people operate under the false assumption that if you just add a keyword enough time to your Web page’s content, that the search engines will rank you according to that number. In reality, search engine designers wised up to that years ago and now search engines scan your text for relevance much like a human would. If you want to know what methods work to improve your ranking on a search page, Jason Pearson has an online tutorial that will teach you how. In The Online Traffic Formula he suggests you choose a specific keyword and use it once in the title, and no more than twice in the text to optimize your page.
