The marketing team of a FMCG brand felt that while their models were identifying the ROI of the marketing spends, the spends were over time getting skewed in favour of short term promotions and the brand was not focusing on building brand value. The basic reason for this was the estimated ROI from advertising was lower than that of promotions – both consumer and trade and therefore, the skew in spends. RainMan agreed that this is a possible outcome as the long term (LT) impact of advertising is not taken into account by these models. The real ROI can be found only if suitable modelling methodology that takes LT into account.
Data was collected for a period of 5 years at a monthly granularity, and RainMan’s solution based on academic studies, was to build a 2 stage model. The first model would estimate the short term impact of advertising and also the impact of other marketing inputs. The second stage model would use a dynamic Base to understand what drives accretion to the base effect – which is positive for the brand.
It was found that the LT effect of advertising was as much as that of the short term impact as one of the effects of advertising apart from recruiting a customer is to retain a customer. This customer gives sales over a period of time and therefore this value need to be considered while deciding on budget allocations.
The marketing plan was optimized based on these new ROIs, with the result that the Brand has grown in strength over a period of time. The marketing team had enough ammunition to defend their correct decision to restrict promotions and invest on building their brand.
