Reviews are a major part of your branding. This is a traditional element that whether it was delivered person to person in sewing circles or watercooler talk, it has always been a powerful marketing tool.
In this day, reviewing has many avenues it takes. The watercooler, the social media websites like Yelp, Facebook, Google Plus, etc, your own site, little known sites like white pages, patch, local, and your own neighborhood chamber of commerce.
How do you cover them all. Well, you can buy a LocalSEO package which consolidates over 300 websites where your business could come up, or you concentrate on the highest Search Rated review sites. These are Yelp, Google Plus,Facebook and LinkedIn.
