Mental Availability

What most people mean

“Brand awareness.” Usually measured by surveys, impressions, or reach metrics. Run ads. Get your name out there. Hit some awareness benchmark and move on to conversion.

In B2C brand science, Byron Sharp made “mental availability” a formal concept. But most B2B marketers either haven’t encountered it or dismissed it as irrelevant to their world of pipelines and demos.

Where the definition breaks

You can have the most unique positioning from the Pyrenees to the Alps, but if no one has ever heard of you it doesn’t matter. And even if people pay attention to you, they may not be ready to buy right now.

That’s the gap. Most B2B marketing obsesses over the small fraction of buyers who are actively shopping. Performance campaigns. Intent data. Lead scoring. All aimed at the people who already know they need something.

But around 95% of buyers aren’t in market at any given time. They’re not searching. They’re not comparing. They’re going about their lives. And when the trigger hits (a new boss, a compliance deadline, a client loss), they don’t start a fresh search from scratch. They buy from the brands already in their head.

If it looks, feels, and tastes like everything else, like lukewarm water, it’s invisible. People’s brains won’t even register it.

How we define it at STFO

Mental availability is the probability that a buyer thinks of you when a buying situation arises. It’s not a stage in the STFO methodology. It’s the outcome of Stages 3 and 4 working together.

Stage 3 (Distinctive Brand) builds the memory structures. Meaning-free assets that tickle different parts of the brain. A mascot, a colour, a phrase, a sound. Things that are distinctive without trying to communicate a rational message. The goal is recognisability. When someone encounters your brand, something sticks.

Stage 4 (Continuous Reach) maintains those structures over time. Getting in front of the right people at the right time, as often as your budget allows. The nonstop activity that puts you in front of your segment so they see you, think about you, and remember you when the time is right for them to buy.

Without distinctive assets, continuous reach is forgettable. Without continuous reach, distinctive assets decay.

The companies that will survive aren’t the ones optimising for a 0.1% increase in trial-to-purchase conversion rates. They’re the ones buyers actually remember. The ones prospects think of first when the trigger hits. The ones that charge a premium because they’re the trusted brand in the category.

What it is NOT

• Not “brand awareness” (awareness is binary, mental availability is probabilistic)
• Not something you build with a single campaign (it’s the accumulated effect of consistent presence)
• Not only for B2C (B2B buyers are humans with the same 95% autopilot brains)
• Not a replacement for positioning (you need both something worth remembering AND the visibility to be remembered)
• Not measurable by impressions alone (being seen is not the same as being remembered)
