Angie’s List, Google and Yelp permit users to write reviews of businesses online, according to Time. Yelp reviews may be submitted anonymously, while Angie’s List reviews may not. Niche review sites, such as TripAdvisor and UrbanSpoon, also allow users to write reviews online, according to The Seattle Times.
Angie’s List accepts reviews of local businesses from paying subscribers only, explains Time. Anonymous users can neither submit nor read reviews. Rated businesses can buy advertising on the site, including paying for their business to appear at the top of search results. Consumer Reports indicates this practice can skew ratings and make reviews less effective.
Google+ accounts are integrated with other products, such as the Gmail email service, notes Mashable. This allows users to write anonymous reviews on Google+ Local to which business can respond, according to Time. Consumer Reports indicates this practice can skew ratings, as consumers sometimes remove or change negative reviews. Yelp also allows users to anonymously review businesses online. It is one of the oldest review sites available and features more than 40 million reviews, as of 2013.
UrbanSpoon is a niche review site focused on food-related businesses, according to the company’s website. Users can create an account using a real or fake name, and they can also connect using Facebook accounts to write reviews. TripAdvisor, a niche review site focused on travel-related businesses, allows users to review flights, hotels, rentals and travel packages.
