BCG Perspectives, Sep 2010
Companies invest staggering sums of money in marketing with surprisingly little rigor. Because it is notoriously difficult to measure and optimize the return on marketing investments (ROMI), marketing executives often rely on rules of thumb—such as spending as a percentage of revenues—to guide their decision-making. Our research and experience suggest that these shortcuts can be imprecise, unreliable, and just plain wrong. We recommend another approach—one that goes beyond marketing to encompass all commercial investments. It integrates a top-down strategic perspective and a rigorous bottom-up analysis.
More than $1 trillion a year is spent on marketing.
The figure is even higher if you include related commercial investments, such as trade spending, price promotion, and sales force incentives.
Many companies spend as much—or more—on advertising alone as they invest in capital expenditures.
As marketing budgets continue to escalate, managers are coming under increasing pressure to prove the value of their marketing investments over time.
At the same time, marketing is becoming much more complex as digital and viral marketing vehicles proliferate and market segments fragment.
Another complicating factor is that marketing performance depends heavily on elements that either are difficult to measure precisely—such as the content of an ad and its creative execution—or emerge over many months and years, such as the impact of marketing on brand perception.
In the face of such complexity, managers turn to rules of thumb, such as spending as a percentage of revenues, to guide their budget allocations for marketing.
To test some of the common rules of thumb used to set spending on marketing, The Boston Consulting Group and Marketing Analytics, a leader in market-response modeling, reviewed a data set of comparable marketing-mix models for 75 consumer brands.
In our joint research and analysis, we found a wide variance in marketing impact, efficiency, and return on investment—even across a relatively similar collection of brands.
We also found that five of the most commonly used rules of thumb for marketing investments had no clear, consistent relationship to marketing performance in the sample we reviewed.
Managers who rely on such rules, therefore, could be using the wrong approaches to allocate their marketing budgets across business portfolios and the marketing mix.
Rather than look for shortcuts, managers should embrace the complexity of optimizing returns on marketing. We recommend that they integrate a top-down strategic perspective on commercial investments with a rigorous bottom-up analysis.
Such a comprehensive approach would incorporate all the tactics that managers generally consider when they are optimizing ROMI, as well as those that fall under the broader banner of return on commercial investments (ROCI).
Managers could use this approach to evaluate commercial investments dispassionately, on the basis of their ability to drive incremental sales, influence consumers at every point in the purchase decision, and build brand equity for the long term. Consequently, companies would spend on the right things, spend in the right ways, and be able to measure and optimize that spending continuously.
To achieve these goals, corporate leadership must establish a sustainable capability to measure and optimize commercial investments. Only then will they begin to reclaim the 15 to 30 percent of spending that typically is wasted today.
