According to Google Trends, it appears there may have been a significant drop in traffic from Google referrals to major Internet Yellow Pages (IYPs) sites:
Yellowpages.com, Superpages.com, Yelp.com, Citysearch.com, and WhitePages.com all look like they’re dipping in sync.
Is it possible that IYPs have fallen under the treads of a Panda update?
It’s still perhaps early to tell, but it’s looking like they’re all experiencing something similar.
