Yahoo directory or DMOZ directory.

Links from which directory to your site is more important?

[MeTi]

in my opinion i think DMOZ is more important.

[Mark]

Thanks Meti, but can you please explain why is it important?

Dmoz listings have a percieved quality about them. If you do manage to get a listing in dmoz, it means your site meets a certain standard in the opinion of the dmoz editor.

Yahoo also have some standards in the submission process, but to a lesser extent than dmoz. Also you need to pay $299 for a listing.

Both DMOZ and Yahoo! directories serve a distinct purpose for webmasters in search engine query placement & PR, both directories do have their own distinct problems. The listing from both the directories is equally important and valuable so the choice is yours, if you can afford to pay $299 go for Yahoo, if you have a lot of patience then submit to DMOZ.

I would say DMOZ, it's an Open Directory project and the largest human edited directory on the Internet. A listing here results in the site automatically being listed in many other directories and search engines.
