When reach, attention and dashboards become the destination rather than the path, marketing gets more sophisticated, and often less effective argues Luke Brown, Group CEO, AFFINITY
The marketing industry has never had more data, more tools or more confidence. Yet brand growth has slowed, penetration gains are harder to achieve, and the distance between media activity and commercial outcomes continues to widen.
This is not because advertising has stopped working. It is because many of the ideas guiding modern media decisions are wrong. Not maliciously wrong. Structurally wrong.
They are attractive because they are simple, measurable and repeatable. They reduce complexity into rules, frameworks and dashboards. But when applied at scale, they optimise media systems rather than grow brands.
The scale of the problem is hiding in plain sight. Global advertising investment has now surpassed one trillion dollars a year. In Australia alone, brands are likely wasting between 20 and 30 percent of their media budgets, collectively around six billion dollars annually, on activity that delivers no incremental growth.
At the same time, corporate earnings growth across many major companies has been driven more by pricing increases and cost reduction than by expansion in net unit volumes. Revenue per unit is rising. Margins are being defended. But in many categories, penetration and volume growth remain subdued.
If reach were effectiveness, penetration would be rising. If attention were effectiveness, demand would be compounding. It isn’t.
The industry now measures more than it understands. It optimises more than it questions. And it reports more than it grows.
Once you see this, it is difficult to unsee it. What follows are not isolated missteps. They are expressions of that structural failure.
Myth 1: Reach equals effectiveness
Reach is exposure. Exposure is not effectiveness. Advertising is only effective if it changes behaviour. That means adding buyers, increasing switching, or expanding buying occasions. In other words, penetration is effectiveness.
Reach matters, but only insofar as it contributes to mental and physical availability that converts exposure into choice. When reach is treated as the outcome rather than the mechanism, activity increases without impact.
This is how reach curves improve while growth stalls. The system reports success while the business experiences stagnation.
Myth 2: Maximising reach is how you apply How Brands Grow
How Brands Grow re-centred marketing around penetration rather than loyalty and demonstrated that brands grow by being easy to think of and easy to buy, particularly for light buyers.
But reach was never presented as an end in itself. It was a means of building mental and physical availability.
In practice, that nuance was flattened into a rule: maximise reach. Other conditions that make reach effective - creative strength, coherence, repetition and physical availability - were assumed rather than enforced.
The result was undisciplined reach: scale without reinforcement, exposure without memory, and presence without preference.
Myth 3: Attention is the new effectiveness metric
Attention correlates with recall and certain brand measures. That correlation has encouraged the belief that attention itself is a driver of growth.
But correlation is not causation. People can encode brand cues quickly. Low-attention environments can perform extremely well when reach is broad, cost is efficient and repetition is sufficient. When media plans are optimised primarily for attention scores, reach and frequency are often sacrificed, reducing total impact.
Attention can explain variance in outcomes. It does not create growth on its own.
The danger is subtle. Media systems begin to reward what looks impressive rather than what compounds over time.
Myth 4: Digital is more cost-effective at building brands
Cross-channel comparisons frequently show digital platforms outperforming traditional media on short-term brand metrics and cost efficiency measures. This is often interpreted as evidence that digital is inherently superior at building brands.
What these comparisons actually reflect is marginal efficiency on established brands.
Most large datasets are dominated by mature brands with significant existing mental and physical availability. Many were built through decades of mass media investment, particularly television. Digital environments often appear efficient because they harvest brand memory that already exists.
If digital platforms were inherently superior at building penetration, broad-based brand growth would be accelerating globally. It is not. This is not a platform failure.
It is a measurement problem.
Myth 5: Better dashboards mean better marketing
Modern marketing can measure almost everything: reach, attention, engagement, brand lift, efficiency.
The problem is not measurement. It is what those measures are mistaken for.
Most media metrics are proxies, not outcomes. Proxies can improve without adding a single buyer. They can move while penetration flatlines. They can be optimised endlessly while brands stagnate.
This is the quiet failure mode of modern marketing: activity improves, reports become more sophisticated, and growth remains elusive.
The real problem: undisciplined reach
Undisciplined reach does not merely waste money. It actively damages brands.
By spreading weak, inconsistent or fragmented messages at scale, it accelerates mental availability dilution. Instead of reinforcing memory structures, it erodes them. Instead of making brands easier to choose, it makes them easier to ignore.
More exposure. Less impact. This is the form of waste that rarely appears in dashboards but compounds over time.
A more useful definition of effectiveness
Advertising works when it drives growth. Growth comes from penetration, switching, mental and physical availability, and incrementality.
Reach, attention, efficiency and brand metrics are useful only insofar as they contribute to those outcomes. When they become goals in their own right, the system optimises itself away from growth.
The uncomfortable conclusion
Advertising did not fail. The science did not fail. How Brands Grow did not fail. What failed was how those ideas were translated into practice.
Reach is not effectiveness. Penetration is.
Until the industry stops mistaking exposure for impact, it will continue to spend more, measure more, and grow less. And once you see that pattern, it becomes difficult to accept the old arguments again.
