Online Display Advertising for CPG Brands: (When) Does It Work? /
By B.J. van Ewijk, A. Stubbe, E. Gijsbrechts, et al. Published in the International Journal of Research in Marketing.
Give it to me in one sentence.
For the average CPG (consumer packaged goods) brand, online display advertising does not improve sales, but there are some interesting exceptions.
Give me a little more detail.
The researchers used data from AC Nielsen to analyse the ad spend of Dutch CPG companies between January 2016 and March 2018, resulting in a sample of 154 national brands across more than 60 categories.
They then measured the effect that online display advertising had on sales for those brands, and investigated a number of variables. Among other things, the researchers discovered that:
- For the average CPG brand, online display ads on their own do not increase sales in either the short or long term. And using digital display ads in conjunction with other forms of advertising (TV, print) dampens sales as often as it boosts them.
- But display ads can increase sales for brands in high-involvement categories.
- High-involvement products that are hedonic in nature (i.e. they appeal to people’s sense of luxury or fun) are more likely to get a sales bump when they combine online display ads with other media. Conversely, for high-involvement products that are utilitarian in nature, online display advertising produces a significant sales effect only when used as a standalone (i.e. not supported by TV or print).
- Display-ads work better when brands deploy them consistently, not in bursts of activity. In fact, a sufficiently low level of volatility of online display advertising will produce significant sales effects for all categories of products, except for low-involvement utilitarian goods. The researchers say the observed impact of volatility is ‘consistent with the observation that display ads are less subject to tedium and wear-out, and can play a role in multiple stages of the purchase funnel.’
Why is this interesting?
Display advertising has not, according to the researchers, been subjected to a large-scale empirical analysis like this before. And as you can see from the above, the study yielded plenty of practical insights and applications.
For us, the big omission is that the research did not take into account the quality of the creative work used in the display advertising. But to be fair the study was already complicated enough.
