I know it's an older thread but I gotta say, back in the day the ROI for Angie's List was at least 600% better than any other marketing we did. I wasn't the only one who had great experiences with them either, but those days are long gone.
I remember making a post on PaintTalk back in 2016 when they did their first major restructure for the worse regarding no longer charging membership fees for people to use their service. The only great selling point back then was that you could usually trust the reviews, since members paid to be there and the services they used were confirmed. As soon as they opened the gates, it watered down all the good reviews, inflated all the sketchy ones, and reviews couldn't be trusted. Not only that, but the revenue lost from not charging a basic user fee had to made up somewhere, and they did so primarily out of the pockets of the Contractors who paid to advertise with them. I never advertised with them again, and since not paying, I don't think I've gotten a single job from someone finding me there. They've continued to spiral down the toilet ever since.
