Dev · boredAnother ad that won’t tell me the price. Scrolling.

Claire · skepticalCute, but is it made here or just sold here?

Renée · temptedI’d buy it, but rent’s due Friday. Maybe next payday.

The people you never hear from.

A few people complain and a few rave. Most just scroll past, and you never find out why. The crowd tells you.

Overpriced.

Love this bag.

An example debrief

One finished campaign, debriefed.

Bärig, a travel bag maker in Montreal, ran one ad through September: $20 a day, people interested in travel, four orders on $608. This is the line your client reads first.

Bärig's ad photo: a pine-green waxed-canvas backpack with a tan leather handle on an airport gate floor — The ad as it ran. Bärig is a made-up brand, and the photo is generated.

The top lineSimulated

512 people clicked and 4 ordered. The crowd says the ad left out what they clicked to find: the size in centimetres, what's inside, and why it costs $219.

The full debrief has the takeaways, what to change next, and behind them what happened, why now, what the crowd noticed and who it missed, with the quotes each point rests on. Every debrief comes as a page and as slides you can edit.

What's real, and what's simulated.

Your client gets the why behind the numbers, and nobody has to pretend they surveyed the audience.

Observed

Your numbers, untouched.

What the platform reported, with its dates and definitions. We never change a number or add one of our own.

Context

The month it ran.

What was in the news in your client's category before and during the campaign, each item dated and sourced.

Simulated

The crowd's side.

What people like your client's customers would say about the ad, that month. Likely reasons and better questions, clearly marked, for you to check.

How the crowd works.

The crowd's side of a debrief comes from three layers, the way real life works. Follow one ad through all three, step by step.

Real people, recreated.

Every person in the crowd has their own wants, worries, habits and moods. Together they're made up the way the real public is, so the crowd looks like the people you're trying to reach. We call them locals.

PRICE · THIS WEEK Checked-bag fees jump again

Caught up on the month it ran.

Before they see your ad, they read the news your client's customers read before and during the campaign, and nothing after. So the same ad gets a different debrief in May than in September.

Then they see the ad you ran.

And react the way people like them would have that month: stop or scroll past, click or not, and say what they think.
