An ad agency can create demand. It usually cannot see what that demand became.
A focused ad agency can be very good at campaign structure, creative, bidding, and channel management. If the job is to run Google or Meta well, specialization has real value.
The limit appears after the inquiry. When signed-job value, estimate status, and project fit never return to the ad account, the agency has to optimize around the events it can see. That usually means clicks, calls, and form submissions.
Lead Care Team connects lead generation to the website, CRM context, and signed revenue. The goal is not to replace good channel work. It is to give every future campaign a better business signal.
