All in-store activity has a place in building brands. A recent Deloittes report for the American Grocery Manufacturers Association claims that Shopper Marketing is the fastest growing facet of marketing over there for manufacturers AND retailers.
And this can, and should, extend to in-store signage, demonstrations etc. In fact most manufacturers forget that retailers employ 2.5 million people in the UK, and they all get a discount on the products they buy. So in-store activity carries with it a "captive audience" that tends to reflect the local audience.
However, as a company, we spend most of our time measuring the impact of activity on revenue, and on the shoppers. And you will know yourself that as you look around a store, shoppers are bombarded with messages, often conflicting. So you can have an added value promotion this Christmas, sold at a cut price.
Because most in-store activity is coordinated by, but not measured by, the Sales Department they retain the unique ability to spend more, and deliver increasingly less. Which is why Deloittes said that making Shopper Marketing work required a cross business iniitiative to work at all. But, they said, companies implementing like this claimed they were performing 25% better than the category.
