The synergy in green persuasion: Green celebrity endorsers in green advertising: A study of brand-endorser congruence effects in green advertising

Contains fulltext : 150798.pdf (publisher's version ) (Open Access)This study examines celebrity endorser-brand congruence effects in green advertising on the ads' effectiveness. In an experimental survey, Dutch participants (197) saw ads with a congruent or incongruent celebrity endorser. Extending the match-up hypothesis to a novel match-up factor, greenness, the results show that pro-environmental celebrity endorsers yield more favourable attitudes towards the ad, the brand, and purchase intentions compared to non-green celebrity endorsers. Practitioners can enhance endorser selection and branding strategies for green brand products by using green celebrity endorsers. Pro-environmental celebrity endorsement reaches a wide share of consumers, thus paving the way to more eco-conscious consumerism.21 p
