Andy Hagans at the Link Building Blog wrote his Final Word on the Yahoo! Directory, saying the $299 per year for the listing is well worth the money. I tend to agree, I feel that the listing does add some level of trust to your organic results, be it Google, MSN or Yahoo!
There are some down sides to having the listing, if they screw up your title in the Directory, then you are stuck with it not just for the directory, but also for your the listing in the Yahoo! Search results. That is why I am still pleading with Yahoo! to please enable a No Yahoo! Directory Tag, I assume one day they will - maybe part of Yahoo! Site Explorer.
WE have also seen evidence that a listing may not be automatically removed after one year. Earlier this year, we had reports that Yahoo! Directory Listings Last Longer Then a Year for good or bad. If for some reason, a person find the Yahoo! Directory page, and you have a high popularity rank, you can outrank some of your competitors on that long list, because Yahoo! Directory Ranks Pages by Popularity. Heck, I am number three on the main category I am listed on, and I am number one in the New York region, outranking huge Web consulting firms like Agency.com, Razorfish, and others.
There were also loopholes to getting into the Yahoo! Directory, but if that doesn't work for you. There is a guy at DigitalPoint Forums who is guaranteeing listings in the Yahoo! Directory for only $60 and yes, people have been saying that this guy is delivering.
So the final word on the Yahoo! Directory, I agree - it is worth it, especially for $60.
