Chapter 17: Evaluating IMC Effectiveness
From the business perspective, formal evaluation of brand communication is a must.
Why? The first reason is because the stakes in making an advertising misstep are
high. The second reason is because advertising optimization, i.e., reducing risk by
testing, analyzing, tracking performance, and making changes where possible to
increase the effectiveness of the communication, helps ensure future success.
Principle: The sheer cost of brand communication demand that it be evaluated so the
effectiveness can be understood.
How Evaluation Fits into the Stages of Brand Communication Testing
A complete understanding of the strength of your brand communication is
accomplished through testing, monitoring and measurement. This process is depicted
in Figure 17.1.
In chapter 6, we discussed message development testing; specifically, how concept
testing, semiotic analysis, and pretesting are used to make a campaign as strong as
possible before it ‘goes live’ in the marketplace. Ideally the result of preliminary
testing should be available before large sums of money are invested in finished work
or in media buys.
EVALUATING THE IMC MESSAGE
Questions about impact are critical and must be addressed. If they are not, there is no
proof that a campaign worked, so companies may be tempted to make the mistake of
cutting communication spending that is driving their business.
Any attempt to measure the impact of brand messaging by looking only at sales
numbers poses challenges. Therefore, the impact of brand messaging is typically
measured in terms of its communication effects – the mental responses to a message
that serve as surrogate measures for sales impact. Positive post-campaign changes in
When campaigns don’t work, a very important role of post-campaign message testing
involves understanding what went wrong. Some messages might confuse the
audience; others might fail to get consumers’ attention; and still others might fail to
resonate with consumers. In these situations, campaign message evaluation must
bring these issues to light. Solid campaign evaluation measurement tells us precisely
what a campaign has and has not accomplished.
