I've searched the forums and haven't found much discussion of Yext.

Briefly, Yext allows you to post and manage listings on over 50 local directories, including all the "biggies" except for Google. It includes Bing, Yahoo, Yelp, MerchantCircle, CityGrid, etc. Text has direct API ties to all the directories, so you can post photos, offers, etc, and they are all updated immediately.

It also allows you to monitor review activity across all the major review services (again, except for Google).

I'm interested in hearing opinions on the value of all these local directory listings, both as actually traffic drivers, and their contribution (if any) to search engine rank.

And I'm also interested in thoughts on the value of the Yext service to post and manage all these listings.
