Yelp’s results were released ahead of schedule due to a vendor error caused by PR Newsire, according to a company spokeswoman. Local advertising accounts on Yelp rose 32 percent to about 111,000 in the fourth quarter that was in line with estimates from market research firm FactSet StreetAccount. The San Francisco-based company has been trying to expand outside the United States and diversify into services such as restaurant bookings, event management and payments to counter increasing competition.
