A. There are a few famous online service rating companies, such as Angie's List, Yelp, and Google Plus Local. But when you search on them, are those companies coming up at the top of your search list at those companies trustable?
Unfortunately, based on a report by Consumer Reports, the answer is no!
Typically the top of the list providers are all paid ones, Yelp clearly indicates it with a small sign on the top right of the company's information, but not on Angie's List or Google Plus Local. Plus, many of the reviews are bogus.
In the end, the best route is to seek recommendations from someone you know or can verify.
