What defines the "size" of a company in this context is the number of users/buyers, not the number of listed companies. Thumbtack may have half as many pieces of company info, but I bet the number of users that go to Thumbtack for info is tiny compared to Yelp.
I once read that the Yahoo search ad platform has more advertisers than Google, due to more lax standards. Does that mean that Yahoo ads are bigger than AdWords?
