Yahoo! Directory Submit There's a $299 annual recurring fee ($600 for adult sites). At this cost, you'll have to decide whether it's worth it, according to your own circumstances. The value of a Yahoo! listing isn't the amount of traffic it will drive (which is relatively little) but the quality in-pointing link it provides. New sites looking to establish some critical link popularity may find value in a Yahoo! listing. Established sites may not receive the same value for a listing. Of course, paying the fee does not guarantee that your site will be accepted. Yahoo! will notify you either way -- accept or reject. If you're rejected, you'll have 30 days to fix the problems and appeal the process.
go to Yahoo site explorer or something like that, I just Forget, it's require you to sign in and put meta tag on your web/blog....
