Is a website known by the banner ads it hosts?

While marketers often rely upon banner ads to generate revenues, it is unclear as to how these ads might influence consumer perceptions of host websites. In this paper, we conduct three studies to examine the effect of animation and brand advertised in a banner ad on consumers’ attitude towards a host website, as well as word-of-mouth behaviour. Results of the first study reveal that consumers are irritated with unfavourable banner brands and that irritation, in turn, negatively affects their attitude towards the host website. We demonstrate that banner brand and banner type serve as contextual cues that influence judgements of the host website due to a forward spillover effect. Findings of the second study demonstrate that a host website, corol- larily, serves as a context to negatively influence evaluations of favourable brands mainly for animated banner ads - a reciprocal spillover effect. The third study validates and extends the findings of the first study by adopting methodological pluralism through a different approach to stimuli selection and experimental manipulation. Results indicate that, while presence of animation has a negative influence on the host site and WOM behaviour when the brand advertised is an unfavourable one, it neither benefits nor hurts a host website evaluation and WOM behaviour when a favourable brand is advertised. Managerial implications of our findings are also discussed.
