Greg Sterling had an interesting piece on local database accuracy

What did they find? Shockingly, they discovered there was something wrong (minor to major issues) with 47% of the listings! That’s a remarkably large number. I was truly surprised.

The discussion in the post is of equal interest and well worth a read. My experience with Google’s data is similar. I beleive that it was originally purchased and maintained by InfoUSA and was riddled with problems. The question is whether the partners/local businesses/Search professionals of Google can get the data straight and keep it straight.
