Customer Suitability, in the wild
Where the World Cup's biggest ads actually land
The World Cup is on, and some of the world's biggest advertisers have their big brand ads live. So we ran an experiment. We had our Digital Twins simulate the customer's response to these ads across a range of video content and scored for resonance. Then we put eight non-World Cup UK ads through the identical test: same Digital Twins, same videos. The results were surprising. Read on.
How this works. Parallel is a simulation platform. Our digital twins watch an ad in the context of a video and score how well the pairing lands. Every ad and video in this report is publicly available on YouTube.
Background you'll need
Every ad impression is already checked twice before it's bought. Brand safety asks: will this content harm the brand? Brand suitability asks: does this content fit the brand's values? Nobody checks the third question: is this ad right for the customer watching it? That's Customer Suitability. It's what our digital twins measure, and it's what decides whether an ad lands.
The engine: human-calibrated digital twins, synthetic replicas of consumers, 80.4% accurate against human responses. A panel of 60 is used for the UK audience in this report.
How we measure the fit: how well an ad lands with the person watching, in the video they're watching. The twins score it from 0 to 10 for every ad and video combination.
The nine reasons people watch content, from Reward and Treat to Stay Informed. The need-state is the why behind every resonance score.
The line-up
The eight World Cup ads
What they were scored against
Cooking, cars, music, gardening, property, travel, news: the content Britons watch between matches.
133 football videos plus 29 other sport: tennis, cricket, rugby, fitness.
The result
Even the biggest ads have a surprisingly small sweet spot
Across all 432 videos, football included, the green section is where each ad resonates high: the content that genuinely suits the customer watching. Most creative × content combinations are neither loved nor hated, just neutral.
Is context the driver?
It's not the contextual category. Each has a massive range of resonance.
The obvious home for a World Cup ad is football, then the rest of sport. So we tested those, and went far beyond: food and drink, cars, travel, home and garden, property, family content and more. Score these eight ads inside any category and the answer is the same: the category is a spread, not a signal. On average, a single category spans 2 full points of resonance for a single ad, and the categories overlap almost completely. The lowest and highest video scores inside each, with the mean marked:
Lowest and highest video-level resonance scored by the eight World Cup ads within each content category; the dark tick marks the category mean. Non-football categories from the 270-video panel; football and other sport from the dedicated football run. Video counts differ per row, so compare rows by where they sit rather than by range width. Categories via IAB.
Unsurprisingly, Football is the strongest context of all, followed by Sport generally. But like every other context, it has a big range of low to high resonance inside it. Here's the same ad against two live World Cup videos, opposite ends of the scale:
Football"Harry Kane & Jordan Henderson make history | Panama 0-2 England | Men's FIFA World Cup"
England (official channel)
"That's exactly the mood, honestly think I'll add them to my next shopping list right now."
Football"What are the costs and challenges facing World Cup 2026? | BBC News"
BBC News
"Strange switch to jump from BBC analysis into this noisy celebrity party."
Both are live World Cup videos, and the contextual category can't tell them apart, because the category doesn't know why anyone is watching. One viewer is celebrating a famous win. The other is weighing up costs and challenges. An ad built for the celebration falls flat in the analysis. So if the category can't explain the gap, what does?
The driver
It's the need-state the viewer is in.
Group videos by the reason someone pressed play (a treat, an escape, staying informed) and everything snaps into focus. Here are the eight World Cup ads next to eight non-World Cup UK ads (energy, money, cider, holidays and more), scored on the same twins and videos, split across the nine need-states:
Average resonance by need-state, 0–10, same twins and videos for both sets. World Cup ads: this report's eight. Non-World Cup ads: the 8-ad baseline.
Next to the non-World Cup ads (the grey bars), the shape is clear. World Cup ads win the two fun moments: Reward and Treat, where they peak higher than anything else we scored (8.6 vs 6.9), and Escape and Entertainment (7.1 vs 6.8). They run cooler on the other seven. That extreme shape is why their strong-fit territory is so small. A specialist ad in the wrong moment is wasted money. In the right moment it beats everything. So the question that decides performance is which moments suit your ad: that's Customer Suitability.
The secret weapon?
The Sir David Effect
We didn't mention it earlier, but 4 out of 8 of the World Cup ads we simulated featured David Beckham in them: Walkers, Stella Artois, Pepsi and McDonald's. So the big question is: does Sir David earn his fee? Compare his ads to those without Beckham:
So what's the answer?
All Contexts? Football Contexts? No: Just optimise to resonance.
We score your ad against every video: that's Customer Suitability. The need-states explain why it lands and the output is simple: an optimised list of the videos where your ad genuinely suits the customer watching. Activate those, skip the rest. For the first time you can optimise to a resonance goal, instead of riding the low-to-high range inside every context. Simulated for these eight ads, same videos, same twins:
Simulated delivery, averaged across the eight ads.
Every impression gets checked for brand safety and brand suitability. Customer Suitability is the missing check. We score it for every impression and optimise your buy in real time.
