Marketing Effectiveness


In the 20 years since its launch in the U.K., by 2014 Lidl commanded a 3.1% share of supermarket sales. During this period, its marketing strategy was dominated by short-term deals and offer marketing. The Media and Marketing teams wanted to understand how they could optimise their marketing investment to change perceptions of the brand and also grow more quickly, using the right messaging and the right creative executions in the right media channels.


Through a combination of short-term and long-term econometric modelling, we provided Lidl with the rationale they needed to evolve both the messaging and the placement of their advertising. Our analysis identifies sales that are driven by and attributable to advertising, and separates this out from the impact of the increased number of stores – presence and visibility of the brand on the high street – and longer-term brand momentum. It can also isolate the effects of a cluster of other factors, including: competitor activity, price, and changes in Lidl’s range of products offered.

By properly understanding the role and impact of both price-promotional and brand advertising, we helped Lidl to justify and protect an upweighted spend on TV to deliver a mass market audience. We also enabled them to get the balance right between brand building and promotional advertising, with more investment behind TV and radio to drive reach, but less in underperforming channels particularly around digital.


Between 2014 and 2017, brand advertising helped Lidl’s U.K. market share to grow from 3.1% to 5.3%. Our econometric modelling measured the amount of growth driven directly by advertising. We also demonstrated additional growth that was attributable to the long-term impact of advertising on brand momentum.

Positive improvements through enhanced brand perceptions were evident in better scores across the board in brand metrics accounting for "quality", "consideration", and "purchase intent". Over the five years to 2017, profit return on marketing investment increased significantly with the new advertising strategy, with both efficiency and spend increasing. This was achieved through a combination of broad reach advertising (and share of voice), a larger store estate, as well as an optimised channel mix and a new creative strategy designed to tackling misperceptions about Lidl.
