What are category entry points?
The situations, needs and moments that prompt someone to think of a category at all — and the argument, from the Ehrenberg-Bass Institute, is that brands are chosen by being mentally available at those moments rather than by being preferred in the abstract.
The shift in thinking. Traditional positioning asks who your customer is and what they think of you. Category entry points ask when and why the category gets considered, and whether you come to mind then.
Examples for a food brand: a quick weekday lunch, feeding children after school, something to take to a colleague's leaving do, a treat after a difficult day. Each is a different entry point, and different brands come to mind for each.
Why this framing matters:
It explains buying behaviour better than loyalty does. Ehrenberg-Bass research consistently finds most buyers are light buyers who purchase a category rarely and switch readily between several acceptable brands. They are not deeply loyal and they are not comparing carefully; they buy what comes to mind in that moment.
It reframes what advertising is for. Not persuading people you are better, but building and refreshing memory links between your brand and the situations where the category is bought. Advertising builds availability rather than preference.
It explains why broad reach beats narrow targeting in this tradition. Since most future buyers are light buyers who are not currently in the market, reaching a narrow segment of existing heavy users misses almost everyone who will buy.
More entry points means more growth potential. A brand linked to one occasion is retrieved only then; a brand linked to many is retrieved more often.
How they are researched: asking buyers to recall recent purchase occasions and what prompted them, then mapping which brands are associated with which situations, and identifying where you are absent.
The related concepts: mental availability — being thought of; physical availability — being easy to buy; and distinctive brand assets, the colours, shapes and sounds that make a brand retrievable.
The critique is that the evidence comes largely from repertoire categories and generalises less well elsewhere.
