“Not everything that can be counted counts, and not everything that counts can be counted.” — William Bruce Cameron, Informal Sociology, 1963

The most-quoted number in experience design is the one that matters least.

It is footfall. The visitor count. The big figure at the top of the post-launch report, on the slide with the photo of the opening-night crowd. “We did two hundred thousand in the first month.” Everyone nods. The number feels like proof.

It is not.

Footfall tells you a door opened and a body passed through it. It tells you nothing about what happened to that person inside, or whether they left feeling anything at all. And in brand experience, the feeling is the entire product.

Why we reach for footfall anyway

We reach for it because it is easy. It is the one number you can get without trying. A sensor on the door, a ticket scan, a clicker in someone’s hand. No survey, no interpretation, no awkward conversation about whether the work actually moved anyone.

Easy to count is not the same as worth counting. We measure footfall for the same reason the man in the old joke looks for his keys under the streetlight — not because that is where he dropped them, but because that is where the light is.

And once a number is in the report, it starts making decisions for you. Footfall rewards the loud entrance and the photo moment. It quietly punishes the slow, the considered, the room you are meant to sit in for twenty minutes. Optimise for the count and you will, without noticing, build a place designed to be entered rather than experienced.

What footfall hides

Stand in a finished space for an afternoon and you can see the things the headline number leaves out.

You can see dwell — whether people stay for forty minutes or four. You can see depth — how many parts of the experience they actually touch, versus how many they walk past on the way to the exit. You can see the faces. You can tell, with embarrassing accuracy, whether someone is moved or merely processing.

None of that reaches the report. The report says the number was green.

A few years ago I worked on an experience centre that hit its visitor target in the first quarter, and the client was quietly miserable about it.

The footfall was excellent. People came. They scanned in, walked the loop, took a photo by the obvious thing, and were back on the street in under ten minutes. By the only metric on the dashboard, it was a triumph. By every metric that was not on the dashboard, it was a polite failure.

We had built something people would enter. We had not yet built something they would stay inside.

The fix was not more marketing to push the number higher. It was slowing the space down — giving people a reason to sit, a reason to go deeper, a reason to tell someone afterwards. The footfall barely changed. Everything that mattered did.

The metrics worth the awkwardness

So what should sit next to footfall? A handful of things, none of them as clean.

How long they stayed. How much of the experience they reached. Whether they would come back, and whether they would send someone else — the closest thing we have to an honest verdict. And, a week later, what they could still describe without prompting. Memory is the real residue of an experience. If they cannot recall it, it did not happen, whatever the turnstile says.

The industry is, slowly, catching up to this. Dwell time, interaction depth and post-visit behaviour now show up in the serious conversations about experiential measurement, where it used to be just attendance. Good. They are harder to game and harder to fake.

The numbers you can trust least

Here is the part I have had to make peace with.

The metrics that matter most are the ones you can trust least.

Footfall is precise. It is also nearly meaningless. The softer measures — did they feel something, will they remember it, did they tell a friend — are vague, self-reported and easy to argue with. Every instinct in a delivery meeting reaches for the hard number over the soft one.

But a precise measurement of the wrong thing is worse than a rough measurement of the right thing. The first gives you false confidence. The second at least points you at the target. I would rather be approximately right about whether people cared than exactly right about how many of them showed up.

I am not arguing that you stop counting footfall. You should count it. It pays for the lights, and a room nobody enters has failed at the first hurdle.

I am arguing that you stop letting it be the headline.

Next time you brief an experience, or sign one off, ask for the second number before you celebrate the first. How long did they stay. How deep did they go. Would they come back, and a week on, can they still tell you what they saw. Those answers are messier, and slower, and harder to put on a slide.

They are also the only ones that tell you whether you built an experience, or just a very well-attended corridor.

Measuring brand experience in brief

What is the best way to measure a brand experience?

Use footfall as a baseline, then layer the measures that show impact: dwell time, depth of engagement across the experience, likelihood to return and recommend, and unprompted recall a week later. Footfall proves people arrived; the rest proves the experience worked.

Why is footfall a misleading metric on its own?

Footfall only confirms that someone entered. It says nothing about whether they engaged, stayed, felt anything or remembered it. A space can post strong visitor numbers while failing at everything it was actually built to do.

What is dwell time and why does it matter?

Dwell time is how long a visitor stays in an experience. It matters because attention is the raw material of brand memory: a longer, deeper stay gives the work time to land, while a quick walk-through rarely changes how anyone thinks or feels.

How do you measure something as soft as “feeling”?

You accept that it will be approximate and measure it anyway — through return and recommendation rates, qualitative feedback, and what people can recall unprompted afterwards. A rough read on whether people cared is more useful than a precise count of how many turned up.
