I was wondering if anyone of you has ever faced the marketplace problem of convincing companies to join a platform where visitors can compare services they and their competitors offer.
Companies know that 99% of the people out there compare prices, ratings, etc. before making a purchase decision, but still they are quite reluctan to join marketplaces where their services can be compared side to side to those of a similar business.
What should be in your opnion/experience the right strategy in order to convince them to join you on the marketplace?
"Simply" dominating the SERP results and thus "force" them to work with you?
Also keep in mind that in a marketplace you have a kind of "chicken and egg" problem: no services to offer means no visitors, no visitors makes it difficult to get businnes on board.
