Angie's List charges homeowners to see the listings of good contractors.
Then Angie's calls up the contractors and tells them that they won't be highly visible on the reports unless they pay Angie's.
So even though I've been an A+ plumbing contractor on Angie's for years, you are unlikely to see me on their search. You will most likely see those contractors with a large advertising budget, like Yellow Pages.
You would think that paying Angie's would get you a list of the better contractors, but in reality, you still see the contractors that are paying the most money for leads.
