Synergistic effects of social media and traditional marketing on brand sales: capturing the time-varying effects

Abstract

As social media gains more importance, managers are challenged to quantify its return on sales. The academic understanding in the effectiveness of social media is limited, and in fact the synergistic effects between social media and traditional marketing efforts have rarely been investigated. Despite the dynamics in marketing effectiveness on sales, the time-varying effectiveness of social media has never been studied either. In this study, we capture the time-varying effects of social media and the time-varying synergistic effects of social media and traditional marketing with a time-varying effect model (TVEM) approach. The empirical analyses of a large U.S. ice-cream brand sales reveal that a) the effectiveness of social media and traditional marketing vary over time, b) the synergistic effects vary over time for social media with product sampling and with in-store promotions, c) the proposed TVEM approach has a higher predictive accuracy than the benchmark models, and d) the proposed TVEM approach saves marketing costs by $0.4 million per year, compared to the time-invariant benchmark model. Overall, this study enables managers to not only better understand the synergistic effects of social media marketing and traditional marketing, but also the timevarying effectiveness of their marketing efforts with TVEM approach for better resource allocation.Keywords Social media .

The future of social media in marketing

“…Reports from industry sources have shown that consumers respond better to integrated marketing campaigns (e.g., a 73% boost over standard email campaigns; Safko 2010). In academia meanwhile, the majority of research considering online promotions and advertisements has typically focused on how consumers respond to these strategies through online only measures (e.g., Manchanda et al 2006), though this has begun to change in recent years with more research examining offline consequences to omnichannel strategies (Lobschat et al 2017;Kumar et al 2017).…”

“…Moreover, Rapp et al [28] discuss the positive impact of social media adoption on the performance of B2B companies. From a marketing standpoint, in a recent study on time-varying effectiveness of social media and traditional marketing, Kumar et al [20] show how these different marketing activities produce various results over time, by proposing an approach with a time-varying effect model, which helps save marketing costs.…”

How advertising in offline media drives reach of and engagement with brands on Facebook

“…Cross-media synergy refers to the idea that the combined effect of marketing activities in multiple media exceeds the sum of the individual effects with the ability to create a super-additive effect (Havlena, Cardarelli, and Montigny 2007;Naik and Peters 2009;Naik and Raman 2003;Taylor et al 2013;Vandeberg et al 2015;Kumar, Choi, and Greene 2017;Voorveld, Neijens, and Smit 2011). Earlier empirical research showed that campaigns combining advertising in multiple media can be more effective in terms of cognitive, affective, and behavioural responses than campaigns using only one medium (e.g.…”

“…While research on synergistic effects of social media with advertising in traditional media is still scarce, a body of research on the subject is gradually developing. There are studies showing that combining social and traditional media in one campaign can be more persuasive (Voorveld and Van Noort 2014), or even lead to more sales (Kumar, Choi, and Greene 2017;Srinivasan, Rutz, and Pauwels 2016).…”
