Submitting To Directories: Yahoo & the Open Directory
Directories are search engines powered by human beings. Human editors compile all the listings that directories have. Getting listed with the web's key directories is very important, because their listings are seen by many people. In addition, if you are listed with them, then crawler-based search engines are more likely to find your site and add it to their listings for free.

Preparation
You should prepare before submitting to any directory. This preparation means that you have written a 25 word or less description of your entire web site. That description should make use of the two or three key terms that you hope to be found for.

If you have time, you should consider researching what are the best terms for your site, rather than guessing at these.

It is essential that the description you write not make use of marketing language. So, if you sold shoes and wanted to be found for terms such as "athletic shoes" and "running shoes," you might write a "just the facts" description like this:

Purchase athletic shoes, running shoes, hiking boots and other footwear plus try our cross country trail finder.

You would not want a description like this, which is full of marketing hype, which editors dislike:

World's LARGEST online shoe store with the best prices from the greatest brands!!!!

Submitting To Yahoo
Do a search on Yahoo, and the main results that come back are "powered" by Yahoo's crawler. Despite this, Yahoo maintains its own independent "directory" of web sites, which are compiled by its human editors. Being listed in this Yahoo Directory MAY potentially help you get included and ranking better in crawler-based results, including Yahoo's.

Yahoo has two submission options: "Standard," which is free, and "Yahoo Express," which involves a submission fee.
