One of the most common issues with making documents more search engine friendly is the introduction of text in place of, or in addition to, other forms of navigation.
JavaScript is a favorite for mouseovers and more often drop down and foldout menus. Links inside JavaScript are not indexed by most search engines. If a search engine cannot follow links it cannot find the rest of your web site.
Many times an alternative navigation method based on text links can provide a solution. Another option to JavaScript or DHTML foldout menus is a CSS based menu that performs much the same way. Via SEOConsultants.com, Tanfa offers code for vertical (read first) and horizontal menus. These are search engine friendly foldout menus – cool.
