WHY ‘GREAT ADS’ DON’T ALWAYS WIN: A DATA-BACKED LOOK AT AWARD-WINNING CREATIVITY VS. REAL-WORLD ROI

Walk along the Croisette during Cannes Lions and you’d think the industry has creativity all figured out. Every cabana is wrapped in case studies; every panel insists that “great creative drives growth.” Yet underneath the champagne glow is an uncomfortable truth: the work most celebrated on stage is not always the work that reliably moves the numbers.

That gap is showing up in the data. A new global study from the World Federation of Advertisers and Cannes Lions, summarized by More About Advertising, found that only three in ten multinational marketers say their teams consistently deliver “creative excellence,” even though a majority claim to value it in principle. The same WFA/Lions research highlights a deeper structural problem: creative excellence doesn’t even make the top three priorities for many CMOs, and some brands still don’t have a clear definition of what “creative excellence” means inside their own organizations.

In other words, the industry flies thousands of people to Cannes to celebrate creativity that many brands haven’t operationalized, can’t consistently reproduce, and often don’t know how to measure.

The barriers are depressingly familiar. According to the same WFA survey, 68% of senior marketers point to short-termism as a key obstacle, 45% cite risk aversion, and over a third say they struggle to secure sufficient investment in creative development. That cocktail pushes teams toward low-risk, easily rationalized work: more targeting tweaks, more formats, more tests — but not necessarily more distinctive ideas. The paradox is that Cannes tends to reward bold, fame-driving campaigns, while internal decision-making often rewards exactly the opposite.

Measurement is where the paradox really sharpens. As AdExchanger notes in its Cannes recap, recent studies from Forrester and WPP’s Gain Theory show that brand marketers remain fundamentally unsure how to measure creative effectiveness, especially compared with the well-instrumented world of media ROI. CMOs are on stage defending big, brave ideas, yet back at headquarters they’re wrestling with dashboards that can’t tell them whether that beautiful film, social stunt, or creator collaboration actually pulled its commercial weight. That uncertainty encourages CFO-friendly efficiency plays — cheaper production, performance-optimized formats, generative content at scale — over the kind of distinctive creativity that tends to win Lions.

AI is currently making this schizophrenia worse and better at the same time. On one hand, as AdExchanger reports, marketers are far more likely to invest in AI for efficiency initiatives — automating workflows, generating variations, cutting costs — than for measuring effectiveness. On the other hand, a newer wave of tools is trying to close the Cannes–ROI gap by hardwiring creative intelligence directly into media execution. The partnership between DAIVID and ADIN.AI, described in Search Engine Journal, integrates creative effectiveness models into a live platform so marketers can predict which assets are most likely to work before launch, scale winners in real time, and use historical performance as a benchmark for future creative and media planning.

That kind of infrastructure matters because the context in which creativity lives has changed faster than our evaluation tools. When a brand like Unilever can activate a 300,000-influencer network where most creators use AI to churn content at speed, traditional human panels, quarter-lagged brand trackers, and manual A/B tests simply can’t keep up. The industry’s award culture still gravitates to singular, crafted hero pieces; the real market increasingly runs on thousands of dynamically assembled, constantly optimized creative fragments.

Even in more “classic” brand-building environments, the data shows that what wins applause isn’t necessarily what wins the market. Creative intelligence firm DAIVID’s World Cup analysis, cited by MarTech, ranked Fox Sports’ “Miracle” as the most emotionally engaging ad in its dataset, generating intense positive emotional responses from 56.1% of viewers, well above the category norm. On paper, that’s exactly the kind of metric Cannes juries love: emotional impact tied to long-term brand lift. But as MarTech argues, that “scorecard” is only half the story. The real commercial value emerges when emotionally powerful work is tightly linked to search, video, and measurement strategy so that every spike in attention actually converts into demand.

That’s the heart of the Cannes Lions paradox. The industry has never been better at celebrating creativity — or more honest, in its own research, about how inconsistently that creativity is prioritized, funded, and measured. Awards recognize the visible tip of the iceberg. ROI lives in the unseen systems: how ideas are defined, how they’re de-risked without being neutered, how they’re instrumented so that emotional resonance is connected to business response in real time. Until those systems catch up, plenty of “great ads” will keep winning trophies — and quietly underperforming where it counts.

If you ask CMOs what drives marketing ROI, most will give you a version of the same answer: strong, distinctive creative amplified by smart media. But when you follow the money, a different story emerges—one in which “efficiency,” short‑term performance, and risk management quietly outrank creative ambition.

Survey data makes that disconnect explicit. In a global study of senior marketers representing $141 billion in annual spend, the World Federation of Advertisers found that only three in ten multinational marketers say their teams consistently work to deliver creative excellence, even though a majority claim to “value” it. The same report notes that many CMOs don’t even have a clear internal definition of creative excellence, and that barriers like short‑termism, risk aversion, and underinvestment in creative development dominate decision‑making, according to the WFA/Cannes Lions survey. In other words, marketers talk about “great creative” as a growth engine, but they often treat it as a luxury item rather than a core driver of ROI.

The rise of performance marketing has intensified this skew. The ability to track clicks, conversions, and ROAS gave leaders exactly what they’d long wanted: numerically neat proof that marketing works. As one analysis notes, brands have become “extraordinarily good at measuring demand capture” but lack real‑time signals about how consumer attitudes and intent are evolving before they show up in the funnel, creating a structural blind spot in strategy, as AdExchanger’s coverage argues. Once you can measure lower‑funnel performance with near‑surgical precision, it becomes politically—and psychologically—hard to justify budget for creativity that builds future demand but doesn’t show up as immediate CPA.

That measurement bias shows up in budget allocations. Even as marketers admit they’re unsure how best to measure creative effectiveness, they’re far more likely to invest in AI to drive efficiency than to understand which ideas actually work. Reporting from Cannes highlights that while human creativity was a hot topic on stage, CMOs are still struggling to prove their creative delivers results, and “creative budgets are still wallowing” as teams prioritize AI for automation and cost savings over measuring effectiveness, according to AdExchanger’s Cannes wrap‑up. When you optimize around what is easiest to track—impressions, click‑through rates, last‑click revenue—you inevitably privilege incremental tweaks over bolder, brand‑building platforms.

This isn’t just a brand‑vs‑performance cliché; you can see it at the channel level. Platforms like TikTok are explicitly positioning themselves as full‑funnel engines where entertaining, native‑feeling creative drives both engagement and commerce. With global ad revenue growing at 43% year over year and engagement rates that are multiples higher than competing social channels, TikTok’s pitch is that strong creative within its native formats outperforms generic, repurposed assets, as Neil Patel’s analysis of TikTok’s premium ads explains. Yet many advertisers still treat emerging formats primarily as places to chase cheap reach or quick ROAS tests, underfunding the bespoke creative investment that actually unlocks those performance gains.

Even in a “traditional” medium like out‑of‑home, you see a tension between what planners say works and what they actually buy. OOH specialists argue that the best billboards do “two jobs at once”—making brands both easy to recognize and impossible to ignore—by turning distinctive assets into the core creative idea, not an afterthought. Networks are now backing that up with tools that connect creative and outcomes: for example, Global’s Billboards by Global offering links creative, placement, and real business results through its Outcomes measurement and Global:IQ data platform, showing how outdoor works alongside other channels to drive performance, as described in OOH Today’s coverage. But when budgets tighten, those same “big ideas in public” are often the first to be trimmed in favor of more easily attributed digital spend.

The net effect: marketers publicly endorse the idea that creativity is a key lever for ROI, but their funding patterns reveal a deeper loyalty to things they can report on in next quarter’s board deck. They over‑invest in capturing demand that already exists and under‑invest in the kind of distinctive, memorable work that creates tomorrow’s demand. The industry doesn’t have a creativity problem so much as a budgeting and measurement problem—and until those change, even the most celebrated “great ads” will struggle to get the kind of sustained, scaled investment that real‑world ROI demands.

In the abstract, marketers talk about “great creative” as if it’s a single, universal quality. In practice, what works in one channel can be exactly wrong in another. The gap between award‑show ideals and real‑world performance often comes down to a simple issue: each channel defines “great” in its own way, because audiences use those environments for very different jobs.

Take TikTok. As Neil Patel explains, the platform’s best ads are almost indistinguishable from the content in the feed. The algorithm rewards pieces that entertain or inform first, and “sell” second. Strong creative there looks like lo‑fi, native video: fast hooks, human faces, jump‑cuts, text overlays, and a payoff within the first three seconds. A beautifully lit, slow‑build brand film that wins a craft award may simply die on arrival in a TikTok auction, outcompeted by a creator talking straight to camera with a clear, punchy benefit and a discount code.

The same piece of creative would struggle just as much on a six‑second YouTube bumper or in a search ad. “Great creative” in performance search means the opposite of cinematic subtlety: ruthless clarity in keywords, relevance in ad copy, and a landing page that resolves intent with minimal friction. In this environment, the “idea” is often the match between query, promise, and page, not a narrative arc. You can absolutely bring brand personality into those constraints, but the levers that drive ROI are structural and data‑driven, which is why platforms pairing creative intelligence with media optimization—like the AI‑scored content systems described in Search Engine Journal’s coverage of ADIN.AI—are emerging as a new definition of effectiveness.

Contrast both of those with classic out‑of‑home. A great billboard cannot behave like a TikTok; it has seconds, not minutes, and it has no audio, interactivity, or targeting beyond location. As OOH Today points out, the best billboards “do two jobs at once”: they make a brand easy to recognize and impossible to ignore. Distinctive assets—logos, colours, characters, packaging—aren’t end tags; they are the idea. Design constraints drive creative excellence: one core message, one visual joke or striking image, and a brand signature readable at 70 miles an hour. A film script with layered dialogue simply doesn’t translate to steel and vinyl.

Even within digital, “great” splits depending on whether the channel is operating at the top, middle, or bottom of the funnel. On TikTok, for instance, the same platform can host brand storytelling, social proof, and hard‑selling product demos. But as Neil Patel’s analysis of TikTok’s commerce push shows, the formats that drive TikTok Shop sales tend to look like creator‑led, benefit‑driven content, not mood films. Brands that run only glossy “equity” assets there risk missing the full‑funnel power of the channel; brands that run only aggressive direct‑response assets risk burning out attention and undermining long‑term distinctiveness.

The complexity multiplies when you scale creative across dozens of platforms and markets. In the Unilever‑style creator networks described by Search Engine Journal, “creative” isn’t a single hero film; it’s hundreds or thousands of small bets, each tuned to a niche audience and format. In that world, the question is less “Is this idea brilliant?” and more “Does this version of the idea meet the behavioural norms of this feed, in this country, today?” Human judgement still matters, but measurement infrastructure—the ability to score and adjust creative in real time—becomes part of what “great” even means.

This is where many client organisations feel unmoored. The WFA/Cannes research, summarized by More About Advertising, notes that some brands are still “developing a definition for creative excellence.” That’s not just a philosophical problem; it’s a channel problem. If your internal definition is anchored to film craft and big‑idea storytelling, you will systematically undervalue scrappy, data‑driven content that quietly prints money in performance channels. If you define excellence only by click‑through and last‑click ROAS, you will underfund the billboard, the video, or the social series that builds mental availability and pricing power over years.

The uncomfortable truth is that there is no single hierarchy where “best” creative lives at the top and everything else is compromise. There are only ideas that are brilliantly matched—or painfully mismatched—to the way people actually use a given channel. When award juries and ROI spreadsheets disagree, it’s often because they’re grading different sports.

If you want to know whether “Cannes‑style” creativity actually beats conversion‑first work, you can’t rely on case studies or awards write‑ups. You need a controlled test that forces both approaches to compete on the same brief, budget, and audience — and then you measure what really moves the numbers.

A robust design starts with two clearly defined creative philosophies:

• Cannes‑style concept: A big, emotionally led platform built for memorability and storytelling. Think filmic craft, a strong central idea, and distinctive execution that would feel at home in a reel of festival winners.
• Conversion‑first concept: Direct, qualifying, highly functional creative where every element exists to drive the next action — click, search, add to cart, lead submission.

From there, you structure an experiment that pits them against each other in conditions where both can, in theory, succeed.

1. One brief, two interpretations

Both creative streams should answer the same business question (e.g., “Increase sign‑ups for X product by Y% in Z market over eight weeks”), with shared constraints on offer, price, and media budget.

Within those constraints, you give the “Cannes” team permission to chase emotional impact and fame, and you direct the “conversion” team to build around explicit qualification and clarity — similar to the way AI‑driven platforms now reward creative that clearly signals audience and need state. The point is not to make one deliberately weak; it’s to let each side be the best version of its own philosophy.

2. Match channels to their jobs

To avoid a straw‑man test, you deploy each creative style in channels where it has a plausible right to win — but with overlapping coverage so you can see how they behave under the same conditions.

• Upper/mid‑funnel (video & display): You might run both versions in online video and connected TV, where emotionally intense work, like the Fox Sports “Miracle” World Cup spot that topped DAIVID’s engagement rankings, is supposed to shine. Here you track brand lift, search lift, and assisted conversions.
• Performance environments (search, PMax, TikTok, paid social): You then use the same product and offer in formats designed to capture demand. The conversion‑first assets will lean into explicit headlines and qualifying language; the “Cannes” assets will maintain the big idea but adapt it to shorter, more direct executions.

On platforms where creative has effectively become the new targeting, this distinction is crucial. In Performance Max, for instance, you’re not testing different audiences so much as different ways of training the same algorithm with your creative signals.

You can also extend the test into environments like TikTok, where native‑feeling, entertainment‑driven ads already blur the line between brand and performance. As Neil Patel explains in his breakdown of TikTok’s premium push, the most effective formats feel like the content people are there to watch and can drive both engagement and commerce — which makes it an ideal lab for seeing whether highly crafted brand storytelling or scrappier, conversion‑oriented videos do a better job of turning attention into orders.

3. Build full‑funnel measurement into the design

To reconcile awards‑style metrics (fame, talk value, emotional reaction) with CFO‑style metrics (incremental revenue, CAC, payback period), you need instrumentation that connects the two.

A solid test plan should:

• Tie creative exposure to downstream behavior. When a TV or online video ad airs, you measure immediate and lagged impact on search volume and site visits, echoing how emotionally resonant spots in.
• Use consistent conversion events. Whether someone hits your brand from TikTok, a Performance Max placement, or an outdoor QR code, you’re optimizing to the same set of outcomes: qualified lead, completed purchase, repeat visit.
• Include brand‑lift and recall diagnostics. Awards juries care about memorability for a reason. Your design should include surveys or panel‑based tools to track which creative platform people remember, and whether that memory correlates with actual purchase behavior.

You can also bring in out‑of‑home as a third creative battleground. Modern billboard networks like Billboards by Global combine scale, tailored creative support, and outcome measurement through platforms such as Global:IQ. That lets you test whether a billboard rooted in a big, Cannes‑ready idea outperforms a brutally simple, conversion‑driven message in driving store visits or site traffic — without relying on guesswork.

4. Pre‑commit to how you’ll call the winner

Finally, define success criteria before a single frame is shot. For example:

• 40% weight: incremental revenue and contribution margin
• 30% weight: cost per qualified action (e.g., leads that pass sales qualification)
• 20% weight: brand lift and search/organic demand effects
• 10% weight: creative diagnostics (e.g., distinctiveness, enjoyment)

This pre‑commitment guards against the all‑too‑common tendency, highlighted in the WFA/Cannes Lions survey of global marketers, to talk about “creative excellence” while ultimately defaulting back to whichever metric makes the latest campaign look good.

When you put “great ads” on trial in this way — on equal footing, in mixed channels, with shared KPIs and modern measurement — you create the one thing Cannes reels and platform case studies can’t: a falsifiable test of whether award‑winning creativity really earns its place in a performance‑obsessed media plan.

If the Cannes juries trade in words like “brave” and “bold,” performance marketers usually reach for “lift” and “ROAS.” A creative scorecard is where those languages meet. It turns fuzzy talk about “excellence” into a small set of observable signals you can score before, during, and after a campaign — and then correlate with actual business outcomes.

The first shift is philosophical: stop using awards criteria as your north star and start from the jobs each channel and campaign must do. TikTok’s best ads, as Neil Patel’s analysis of the platform points out, don’t feel like intrusions; they behave like the content people are already watching, with the algorithm rewarding entertainment value over follower count. Billboards, by contrast, live at the other extreme of attention. As Global’s new Billboards by Global network puts it, the best outdoor ads make brands “easy to recognize, and impossible to ignore” in just a few seconds. Those are wildly different definitions of “great” — and your scorecard needs to encode that.

A practical scorecard has three layers: brand, behavior, and business.

1. Brand signals: distinctive and on‑strategy

This is where you judge whether an idea is not just “cool” but clearly yours.

• Distinctive Brand Assets in use. You can’t drive recall if your codes barely show up. For OOH, ask whether your logo, colors, shapes, and characters are doing the heavy lifting in the way Global’s outdoor creative principles describe: the brand itself is the visual idea, not a signature tucked in the corner.
• Strategic fit. Score each asset against a single, written job‑to‑be‑done for the campaign: “steal share from X,” “launch Y,” “increase trial in Z segment.” A beautifully crafted film that doesn’t move that job forward scores low, no matter how award‑ready it feels.
• Consistency across variants. As brands scale content production, the evaluation frameworks that used to separate good decisions from bad ones start to strain. The emerging DAIVID/ADIN.AI model, described in Search Engine Journal’s coverage of AI‑driven creative scoring, is instructive here: it links a common creative scoring system to media results across thousands of assets, so “on‑brand” and “off‑brand” aren’t gut calls — they’re patterns visible in performance data.

2. Behavioral signals: what people actually do

Next, you score what happens in the real world when someone encounters the ad.

• Thumb‑stop or glance‑grab. On TikTok, that’s early view‑through rate and watch time; on billboards, it’s whether the concept is legible at speed and distance. You can build simple heuristics (fewer than seven words for OOH; logo and product visible in the first second for short‑form video) and mark assets up or down before spend goes live.
• Engagement quality. Not all likes are created equal. Following the “treat new formats as learning investment” guidance from Neil Patel’s TikTok playbook, you can track which creative patterns reliably drive saves, shares, replies, or shop visits — then codify those into the scorecard as positive behaviors, rather than chasing vanity metrics.
• Pathway clarity. Great creative doesn’t just entertain; it makes the next action obvious. Score whether the offer, CTA, or brand destination is both visible and aligned with the platform’s native behavior (e.g., swiping to a TikTok Shop product vs. hunting for a tiny URL).

3. Business signals: leading and lagging impact

Finally, you connect those upstream signals to what the CFO cares about.

The WFA’s “Clients and Creativity 2026” study, summarized by More About Advertising’s coverage of the findings, shows most large marketers still prioritize efficiency over effectiveness and lack a shared definition of creative excellence. A scorecard helps close that gap by forcing teams to log:

• Pre‑launch: predicted effect. Use historical benchmarks or models, as in the DAIVID/ADIN.AI “live loop between creative intelligence and media execution” highlighted by Search Engine Journal, to tag each asset as high, medium, or low likelihood to drive your core KPI.
• In‑flight: relative performance. Don’t just watch ROAS at the campaign level. Compare assets with similar media support and audiences, then score creative that consistently outperforms the baseline. That becomes your new reference for “effective excellence.”
• Post‑campaign: durable value. Did recall, search volume, or branded traffic grow in markets exposed to the work? Platforms like Global’s Outcomes modelling are designed to tease out outdoor’s contribution alongside other channels, and those findings should feed back into the scorecard so the next brief starts smarter than the last.

The result isn’t a rigid checklist that kills originality. It’s a shared, cross‑functional language where the CMO, media lead, and creative director can all see the same signals — and where “great ad” stops being a compliment and starts being a measurable hypothesis about how creativity drives ROI.

Closing the blind spot doesn’t mean choosing between “Cannes film” and “Facebook feed.” It means forcing brand‑led creativity and performance discipline to work as one system: one strategy, one test plan, one source of truth.

The first move is structural. Performance marketing’s biggest success has been building a continuous optimization loop around measurable outcomes: launch, learn, reallocate, repeat. But as one analysis of the field points out, that same success has created a growth ceiling by over‑training teams to prioritize only what can be tracked in-platform. To close that blind spot, you apply the same loop to brand. You treat awareness, consideration, and creative quality as variables you can instrument, not as mystical side effects.

In practice, that means your “brand work” must be designed to behave like performance work:

• Every big brand platform is decomposed into testable creative territories and distinctive assets.
• Every execution ships with a measurement plan that spans brand lift, behavior in-platform, and downstream revenue — not just one of the three.
• Every learning feeds a shared creative scorecard that both the CMO and the performance lead actually use.

Channel choices then become design decisions, not dogma. Out‑of‑home, for example, has often been treated as pure awareness, immune to the rigor of performance. But modern billboard networks are being rebuilt around data and outcomes. The “Billboards by Global” platform, for instance, doesn’t just trade on spectacle; its Global:IQ stack uses exclusive datasets to identify audiences, optimize locations, and model outcomes, so planners can see how outdoor is contributing alongside other channels. When the medium itself is architected for both scale and measurement, creative teams are forced to ask a different question: “What’s the most memorable idea we can deliver, using brand assets people can recall, in formats where we can actually prove business impact?”

The same convergence is happening in digital. TikTok isn’t selling itself as a social network with ad slots; it is positioning as a full‑funnel engine where entertainment, commerce, and performance meet. Its native ad formats are designed to feel like the content users already watch, and the algorithm rewards creative quality over account size, which means the right idea can massively over‑deliver on reach and engagement. At the same time, TikTok Shop’s rapid growth — with billions in sales and a substantial share of buyers discovering products via ads — shows what happens when you architect creative, media, and commerce together from day one. The brief is no longer “make something viral” versus “hit a ROAS target”; it’s “design an entertainment‑first idea that can be measured all the way to purchase and iterated weekly.”

Organizationally, this integration requires more than dashboards. Research from the World Federation of Advertisers and Cannes Lions found that only a minority of multinational marketers consistently push for creative excellence, with short‑termism and risk aversion cited as major barriers, even as many are trying to build more systematic ways of working. Closing the gap means hard‑wiring creativity into those systems: creative excellence becomes a capability with defined behaviors, inputs, and metrics, not a poster on the wall.

The practical end state looks like this:

• One blended roadmap. Brand platforms, tentpole moments, and performance sprints are planned together, with clear hypotheses about how each fuels the other.
• One shared scorecard. Brand‑side cares about cost per incremental lift and revenue contribution; performance‑side cares about distinctive assets, storytelling strength, and mental availability.
• One test culture. Big creative bets are pressure‑tested through structured experiments, where Cannes‑style thinking and performance‑native formats compete on equal footing against the same KPIs.

When those conditions are in place, “great ads” stop being a matter of taste or trophy count. They become the work your market keeps rewarding — not just with likes and views, but with attention, preference, and cash — across every channel where your brand shows up.
