Will it? For a site ranked #12 on average on google.com for a certain keyword, and with PR3, will Yahoo make a difference in putting it up to Page 1?
No it does not effect any more on google.But if you are considering Bing And Yahoo then it is necessary.Otherwise useless. -------------------------- Dallas Internet Marketing | Web Design Dallas
It would have some effect if you submit to Yahoo! Directory in tandem with other quality directories.
I don't think that it will have much effect on google. Investing on Y directory is a total waste if you ask me.
I had few websites listed on Yahoo since a long time ago while others were not, contribute of Yahoo listing on ranking is negligible or at least I can't see the difference. I think a few years ago listing on Yahoo was much more important. Then you should consider direct visits from Yahoo directory, if it can be of interest.
I think Yahoo directory can at least provide a high-quality link, so it is good to do so. To some niche, directories do bring traffic and customers.
Yahoo dir (paid) might help you get referral traffic and Google gives some link juice as well. More than Google, Yahoo ranks your website on targeted keywords. If you aim at Yahoo for large volume of crow, consider enlisting at Yahoo Dir. However, if you want purely for link juice, consider Dmoz, perhaps better option than Yahoo Paid Dir.
