Google has acquired Zagat, a high-end restaurant and shopping reviews publisher, to bolster its local business content. "Moving forward, Zagat will be a cornerstone of our local offering," wrote Marissa Mayer, Google VP-local, maps and location services, in a blog post announcing the deal. Until now, the search giant has populated its Google Places pages with aggregated content from outside sources, which until recently included Yelp reviews. However, Yelp, a user-generated reviews site for local businesses, found Google Places to be in direct competition to its business. With Zagat publishing arguably some of the most respected restaurant reviews and ratings, Google now has its own store of highly respected local content. The restaurant and shopping reviews publisher has been in the business more than 30 years and covers 13 categories in more than 100 cities.
