I spent some time in St. Louis last week on a client visit. When I got back and settled in this weekend, I decided to head over to Yelp to drop in a couple reviews — one for the hotel where I stayed, and one for the local restaurant where we had lunch.

After I wrote my restaurant review, Yelp asked a simple question: Have additional tips on this business? I clicked the link and was presented with this easy-to-use form asking me for additional information about the restaurant, like price range, parking, delivery, and so forth.

I don’t think this is new on Yelp, but it’s the first time I recall being asked to help add to the site’s basic business data. Yahoo Local does a similar thing, where regular users can add or correct business data — and if enough users agree, a business listing gets updated.

I think this is another potentially good way to improve local business data, which is one of the ongoing sore spots where local search is concerned.
