Trada launched a crowd sourcing service for pay per click advertising campaigns. The service connects advertisers and agencies with ppc advertising experts, who are the crowd of experts. This way currently campaigns are created by an average of 24 experts creating thousands of targeted keywords. In the result the cpa is about 10 % lower with creative media being 10 % more effective, Trada communicates. Both advertisers and ppc experts are invited to join the service.
