Most people believe that search engines and directories are the same.
A search engine however, has two parts, a spider and an indexer. To learn more about search engine optimization , visit our tips and FAQs page. Directories will not list your web site unless you register it and submit your main URL in the appropriate category. Since directories use human reviewers to check each site this process can sometimes be very slow. Yahoo and LookSmart have tried to speed up the process by offering a paid review service that says your site will be reviewed within a 2-10 day period.
