Mental availability describes how easily a brand comes to mind when a person faces a buying decision. For many brands it is the biggest lever for growth, bigger than any single campaign and bigger than the loyalty of their best customers.
Today I work as Marketing Director with a team of 22 people across several markets. In this role I see every day how quickly a plan breaks down into many small activities. Mental availability helps me align these activities with one question again: does our brand come to mind at the right moment?
- Brands grow mainly through many occasional buyers, not only through loyal customers.
- Mental availability is built through reach and recognisable brand assets.
- Buying situations decide which message works.
- It is measured through recall in buying situations, not through likes.

What mental availability means
The term comes from the research of the Ehrenberg-Bass Institute, best known through the book “How Brands Grow” by Byron Sharp (see here: Ehrenberg-Bass Institute for Marketing Science). The core message: big brands mainly have more buyers, and many of them buy only rarely.
This leads to an uncomfortable truth for many marketing plans. Those who only play to existing fans hardly grow. Growth comes from more people thinking of the brand in more situations. That is exactly what mental availability means.
Rules 1 and 2: reach and brand assets
Rule 1: reach before frequency. It pays to reach more people occasionally rather than few people very often. For media planning this means deliberately including broad channels and not only buying the cheapest contacts in small target groups.
Rule 2: use brand assets consistently. Colours, logo, shapes, sounds or a recurring visual language make sure advertising is attributed to the right brand. If these assets change too often, the reach builds nobody.
Rule 3: buying situations instead of target group portraits
People do not think in brands but in situations: a jacket for autumn, a gift, an outfit for a trip. These buying situations are the doors through which a brand enters memory. The more situations it owns, the more often it comes to mind.
In practice a simple list helps: which five to ten situations matter for the category, and which ones is the brand linked to today? This produces messages that work across markets, because situations are often more similar than target groups.
Rule 4: measure mental availability
Mental availability can be measured by asking about situations: which brands come to mind when you look for a jacket for autumn? The share of mentions across all situations shows how present the brand really is. How I combine such figures with other brand data is the topic of my post on brand health tracking.
Patience matters. Mental availability builds up over months and decays when a brand goes quiet. That is why it belongs in the annual plan, not in single activations.
An everyday example shows how this fits together. A brand plans an autumn campaign across several markets. Instead of concentrating its budget on a few very loyal customers, it spreads its contacts more widely and uses the same colours, the same motif and the same line in every market. The message connects to a concrete situation, such as the first cold morning. A few weeks later a short survey asks which brands come to mind in exactly this moment. This shows whether the campaign truly strengthened mental availability or only reached those who already knew the brand.
My conclusion: mental availability is not a term for researchers but a practical compass. Planning reach, protecting brand assets, owning buying situations and measuring regularly gives a brand the best chance of being chosen at the right moment.
