Often called directories, these search engines do not use spiders to visit and index your web site. With human indexed web sites, web pages are manually indexed. When you submit your web site to a directory, a living-breathing employee actually examines your site and does the work manually.

Usually, you will be indexed based on where the person doing your indexing feels you belong. Because of this, it is almost impossible to manipulate these search engines when it comes to were you get positioned. Another big difference is directories only index a web site once. Unlike spiders that return and re-index your web site, directories don’t have this option. Once again, getting to the top of directories is not something that anyone can provide as a service because it is left to a person to decide where you belong.

It is not easy to predict what a person may do on any given day. The bottom line is that you should submit your site to directory search engines, even though you have no way of knowing where they will place you.
