Let’s put first things first, what is a metric? A metric is a measuring system that quantifies a trend, dynamic, or characteristic. From this definition one can already deduct that something like a brand can be measured. Being able to ‘crunch the numbers’ is vital in marketing. I will start with penetration from which we can also measure Brand Penetration. With penetration I mean: the proportion of people in the target group who bought (at least once in the period) a specific brand or category of goods. We all know that this can be calculated at Market Penetration (%) = Customers who have purchased a product in the category (#) : Total Population (#).
Brand Penetration calculation is then easy. Brand Penetration (%) = Customers who have purchased the brand (#) : Total Population (#). So if over a period of a month, in a market of 10.000 households, 500 households purchased Coca Cola Light we can calculate this as 500:10.000 = 5% Brand Penetration Coca Cola Light.
Share of wallet
But how do I measure the Brand Loyalty? Loyalty means we have to look for heavy users. We might do that by the share of requirements (share of wallet) which is calculated solely among buyers of a specific brand. Within this group, it represents the percentage of purchases within the relevant category, accounted for by the brand in question. Easier maybe to say that it is the average market share enjoyed by a product among the customers who buy it. To make this clear I give the example that in a given month, the unit purchases of Coca Cola Light is 1.000.000 bottles. But among the households of heavy users that bought Coca Cola Light, t
otal purchases of soft drinks came to 2.000.000. This means 1.000.000:2.000.000 = 50% Share of Requirements/Wallet.Awareness
Even after former examples issues like awareness, beliefs and likeability are still taken for granted and may not (yet) have been put into metrics or performance indicators by marketers. But awareness – the percentage of potential customers or consumers who recognize or name a given brand - can be (un)aided or (un)prompted. To reveal this awareness different kind of questions have to be asked:
To measure awareness: have you heard of Brand X? What brand comes to mind when you think luxury car?
To measure beliefs/likeability: Is Brand X for me? On a scale of 1-5, is Brand X for young people?
To measure loyalty: Did you use Brand X this week? What brand did you last buy?
Next to metrics ther
e are also key performance indicators (KPI’s). Like metrics they indicate what to do to dramatically improve business performance and are connected with the business most important/critical processes. KPI’s therefore indicate the critical success factors. But how to control all these kind of metrics? To get an immediate overview of your business performance the Balanced Scorecard was invented by Kaplan and Norton (1996). A very interesting subject which I may address in one of my next blog posts.Source: Farris et al (2006), Marketing Metrics: 50+ Metrics Every Executive Should Master, Wharton School Publishing.
