Very low lead quality
Thumbtack used to be a good source of quality leads. As a professional plumbing company, we had a good contact and conversion rate. The lead quality has steadily declined while the cost of leads has steadily increased. The value (even while in decline) was still there even if it was diminishing. At this point, Thumbtack has gotten to the point where the quality is so bad, it will struggle to get to break even with them. Very poor... not worth the spend. Put your money somewhere else. The only people who will make money with them is Thumbtack themselves. Legitimate contractors are leaving them in droves, leaving nothing but low end contractors and handymen.
