Directories rely on submissions from users and Web site owners to populate their indexes.
Most directories add your site to their index, but generally they link only to your home page rather than indexing the full text of each page on your site. Most search engines feed off the directories so if your site is not listed with them, there is a good chance that you won't be found in some of the major search engines. Surveys also show that more than 85 percent of website traffic comes from the search engines. Advanced programming techniques like JavaScript and other languages plus having an excess of scripting code can significantly affect your ranking with the search engines. For instance, when we design a site for our clients, we optimize the site at 100 per cent which puts our clients on the first and second page of the major search engines.
