Yahoo! offers diverse services and if you are not in the know about them, you will stop short of making best of it. Now there is help.
Wendy Boswell has given a comprehensive guide submission options for Yahoo! Here is the excerpt from her post-
Yahoo is both a search engine and a directory. By submitting your site to Yahoo's human-edited directory, you may have a better chance of being found by purely spider-driven engines (such as Google). It's best to figure out exactly where your site or content may fit in the Yahoo structure before submitting willy-nilly to anything that has the word "submit" in it. Expect a "reasonable delay" when using any of these site submission options.
There are eight (!) submission options with Yahoo; I'm going to briefly go over them one by one:
* free site submission
* free mobile site submission
* free media content submission
* Yahoo search index submission
* sponsored search
* product submission
* travel submission
* Yahoo directory submit
* Yahoo standard submission
