I turned to David, because it was necessary to establish lead generation on the Internet, in other words, it was necessary to configure contextual advertising, with a clear and transparent end result. An additional service was the technical support of our crm-system and our sites. The main difference was that David has an active position in relation to the solution of our problems. Quick response to the tasks, their implementation, constant interaction with our marketing Department - all this allowed us to get feedback and correct advertising campaigns in time. The initiative on his part to improve the quality of the lead, reduce its value, as well as the cost of the transaction.
