The problem of this market is that the marketers cant hold marketing campaigns, so Google or Facebook arent bad. A real professional can achieve goals in any conditions.
You, right, a real professional will do it in any conditions, but what a price to pay.. Look, 50 persons of 100 can become a companys clients on LeadCoin, but only 2-5 persons form 100 will become clients of the company due to advertisement on FB or Google. This a simple calculation of efficiency of the platform.
