摘要:
This paper investigates how exposure to affects the choices users make of brand-specific pages to view within a website. Using individual-level clickstream data from a third-party automotive website, we tracked the web pages selected by users as they browsed the site and their exposures to premium placement display ads for different vehicle makes (e.g., Ford, Toyota). Pages on the site were classified into those that displayed information about a specific vehicle make (a "make page") versus those that did not (a "non-make page"). For each "make-page" viewed, the specific automotive make selected (e.g., Ford, Toyota) was also recorded. We use these data to develop a model of users' make-specific page choices as a function of prior banner ad exposure on the site. Consumer heterogeneity is captured using a Bayesian Mixture approach. We find that banner ads influence subsequent choices of which make-specific pages to view for ads, served during the current browsing session but not for ads served in previous sessions. The effect of banner ads is also segmented: users in one segment (54%) reacted positively, users in a second segment (46%) were not influenced. Using a standard continuous approach to heterogeneity, we would have concluded-incorrectly-that banner advertising has no effect on the subsequent selection of make-specific pages. For the positively reacting segment, we estimate that the elasticity of make-page choice with respect to banner ad exposure is just under 0.2. Users in this segment appear less focused in their site browsing behavior and tend to stay longer than users in the non-reacting segment.
