Rf. Beltramini et Er. Stafford, COMPREHENSION AND PERCEIVED BELIEVABILITY OF SEALS OF APPROVAL INFORMATION IN ADVERTISING, Journal of advertising, 22(3), 1993, pp. 3-13
This paper reports two exploratory studies on how seal of approval sou
rce, currentness, and longevity affect consumers' comprehension of sea
l meaning and how seals in general impact the perceived believability
of information contained within advertisements. The results indicate t
hat consumers do not comprehend what seals of approval represent, and
in most. cases, do not perceive the believability of ad claims to be e
nhanced by the presence of seals of approval. Implications for researc
hers, advertisers, and public policy makers are discussed.
