How AI shattered the attribution illusion
For years, businesses have systematically underfunded brand investment in favour of measurable, attributable performance campaigns. It’s easy to see why. The data looked fantastic in quarterly reports. Boards loved it. CFOs loved it.
You put £1 in, you could point to a number on a dashboard that said you got £3 back.
However, in many cases that performance marketing success was simply harvesting the demand built by years of brand building before it.
Marketing teams were spending their brand equity without reinvesting in it, under the guise of efficiency.

Now, the well is running dry.
Cost per click is rising year on year across almost every sector. Brands are finding themselves bidding for audiences who have never heard of them, against aggregators and competitors, all paying a premium for every conversion.
In a world with dwindling organic search volume, brands that chose to spend the last decade optimising ad sets instead of building brand affinity will find themselves with nothing left when the paid tap is turned off.
As AI answer engines absorb more and more search queries, the total volume of traditional searches is shrinking. Fewer searches means fewer auctions, and what follows is a brutal squeeze on your paid media budgets.
Less search volume means fewer clicks. Fewer clicks in a more crowded auction means fiercer competition, and ultimately, CPCs are climbing higher and higher. At the end of it all, brands are spending more budget to reach fewer people.
Marketers fell for the performance illusion. The dashboards told us a very compelling story.
Attribution models were built that gave all the credit to the last thing a customer clicked before they bought, completely ignoring the months or years of brand exposure that actually made the sale possible.
As a result, short-termism and instant results were favoured over the slow, unglamorous work of building a brand that people actually care about.
Fundamentally, businesses measured what was easy to measure, and decided that anything not tracked perfectly simply did not matter.
It’s not a media buying problem, it’s a structural one.
While we were busy optimising for impressions, something else was happening. We pushed so hard for attention that consumers have become numb to it. Our brains are now trained to forget advertising the moment we see it.
We created an environment where reach is infinite, but genuine attention is practically zero.
This conditioned blindness, combined with a tsunami of AI-generated content has caused a full-blown crisis of trust.
So, where do we go from here?
The answer is not a new algorithm or a better bidding strategy. The answer is a return to the fundamentals of marketing — a resurrection of the Big Idea.
The campaigns that humans actually remember, the ones that LLMs cite in their answers, and the ones that competitors cannot replicate, are not built in a dashboard.
They are built in the real world. They are built on emotional resonance, human truth, and a clear point of view.
Whether it is an unforgettable experiential event, a piece of bold thought leadership, or a campaign that actually makes people feel something, the mandate for 2026 is clear.
You have to build a brand that people actively seek out, rather than relying on a search engine to serve you up by accident.
Performance marketing will always have a role in capturing demand. But it cannot create it.
AI has already eaten your search traffic. If you do not start building a brand that people care about, your marketing budget is next.
