Importance of Ratings and Reviews
From 2008 to 2009, usage of consumer ratings and reviews increased to 25 percent (+3) among IYP searchers and to 27 percent (+5) among general searchers. Additionally, people who use social networking sites for local business information are more likely to use consumer reviews (53 percent).
It's interesting that, while overall usage of ratings and reviews is only 24 percent, its importance during the business selection process is 57 percent! Because users of ratings and reviews heavily rely on them to select a company to do business with, they should be a serious component of any marketer's online strategy.
