The impact of brand perceptions on the post-to-purchase journey: a family branding perspective

Abstract

PurposeDespite brands’ growing use of social media, most research has overlooked the impact of brand perceptions, particularly that of a family brand identity and perceptions of authenticity. Often the purpose of a social media post is to positively change or enhance these perceptions and, consequently, increase a consumer’s purchase intentions. However, how a post influences purchase intentions, that is, the post-to-purchase journey, is not well understood. This study aims to investigate how characteristics of social media post influence purchase intentions through the mediated effects of social media engagement and perceptions of brand authenticity and how a family brand identity enhances this post-to-purchase journey.Design/methodology/approachDrawing on signalling theory, a sequential mediation model is devised, reflecting the post-to-purchase journey. Starting with identifying desirable characteristics of social media content, the sequential roles of social media engagement and brand authenticity and ending with purchase intentions – with the impact of family brand identity overlayed at each step. This model is analysed using partial least squares structural equation modelling and data from 227 UK consumers.FindingsFour desirable characteristics of social media posts are affirmed – creativity, information, persuasion and inspiration. Each was theoretically justified as costly signals and captured different aspects of effective content, indicating their relative importance. The proposed post-to-purchase journey is supported, with family brand perceptions enhancing each step.Originality/valueAddressing a need to look beyond current conceptualisations and theoretical underpinnings, this paper puts forward a post-to-purchase journey, incorporating brand-related perceptions, resulting in a deeper understanding of how social media builds purchase intentions.
