Advertising agencies have witnessed a steady erosion of their share of
their client's marketing budgets over the past 20 years. In shifting
their budgets away from advertising agencies, clients are indicating t
hat full-service agencies cost too much for the market impact they del
iver. This paper explores how advertising agencies can use client serv
ice to strengthen agency-client relationships. Specifically, this stud
y shows how advertising agencies can improve client perceptions of fai
r agency compensation, agency confidentiality, and rapport by behaving
cooperatively and attending diligently to problems that arise within
their relationships. Alarmingly, when the client observations of agenc
y service were compared to the perceptions of their advertising agency
, rather large discrepancies were found. The risk seems to be that, wh
ile there are numerous ways agencies can improve their relationships,
many agencies may incorrectly believe that they are already doing a su
perb job.
