How AI Decides Which Brands Get Found. And Why You Can’t Ignore It.

GEO, the eligibility tax, and why your performance dashboard is showing you the wrong half of the problem.

Look at a performance marketing dashboard, and you’ll see the usual suspects: CTR, CPI, ROAS. Every QBR, every optimization lever, every discussion about creative, all of it focuses on what happens after the ad runs.

But the priciest problem in performance marketing today isn’t in your media plan. It’s upstream of it, and almost no one is measuring it. 

That’s what Lavinea Morris, our Managing Director for EMEA, covers in her latest Business of Apps interview. Here’s why it matters to marketers.

Attention is also being discoverable

In advertising, we all talk about measuring “attention” without agreeing on what it is: impressions, engaged views, or time on site? Ask ten brands, and you’ll get ten different replies. As Lavinea puts it:

“I think it’s a slightly romanticized metric, this attention piece. We’ve spent so many years focusing on what happens after that first ad, but now we have to be thinking about what happens before the ad is seen. How eligible is your brand?”

Being discoverable isn’t just about showing up in a feed anymore. Platforms and AI assistants are the gatekeepers. Eligibility happens before the impression, before anyone even gets the chance to scroll past your ad. The old filter bubble has leveled, and it’s not simply an algorithm showing you what you already like. It’s an AI agent deciding what you should know exists at all.

Here’s what changes: if your brand doesn’t clear that filter, none of your performance metrics matter because no one will see you. You risk optimizing a ghost.

What is the eligibility tax and why should you care?

Eligibility tax:

“It’s the price that brands pay for not being eligible. This is where we’re seeing an impact on actual performance campaigns’ rising costs, and it’s not always because of the performance media. It’s actually how you’re showing up in these spaces, and are other brands doing better than you.”

Brands see rising CPAs and blame media inefficiency. Conversion numbers go flat even as spend goes up. Brand search tanks while category demand climbs. These are all eligibility symptoms. Meanwhile, your competitors are popping up in the conversations, the recommendations, and AI answer boxes where you’re not. They get the head start, you pay the tax.

Here’s the part we need to realize: this has a compounding effect. You want to be discovered to hold a position. Every quarter you spend invisible is a quarter your competitors deepen their data signals, review density, semantic relevance, and citation graphs. You don’t want this gap to widen.

And yes, you can actually measure this gap. We use test-and-learn frameworks, and we run a dedicated GEO division within our team for exactly this work. When you do it right, the cost of sitting on your hands stops being a hypothesis; you can see it in the numbers.

GEO is the discipline most teams don’t have yet

Generative Engine Optimization is the work of making your brand “legible” to machines. It overlaps with SEO in shape but not in mechanics. We’re talking taxonomy, structured data, content quality, review depth, trust signals, and user flow: everything an LLM uses to decide whether you’re worth showing as an answer.

Which is why an agency’s role has expanded. As Lavinea puts it:

“Our role is broader. Our role is advising on how to make your brand more visible. That’s feeding into taxonomy, into understanding user flow… It’s broadened our role, which makes it so exciting.”

Performance marketing used to be a specialism, but now it’s more of an integration effort. The marketers who stayed in their lane are being called to redirect and broaden their perspective.

Performance marketing is everyone’s job now.

Like it or not:

“Performance marketing isn’t just the performance marketing manager’s job anymore. It’s everybody’s job.”

This is an organizational effort, largely because eligibility touches everything. Engineering tweaks the page structure, and it matters. Product decides how to prompt for reviews, and it matters. Content goes deep or stays shallow, and it matters. CX shapes the post-purchase experience, and it affects it. CX’s choices about post-purchase experience affect it. None of these teams sit traditionally inside performance marketing. All of them now own part of its outcomes.

Media buying as a standalone effort is commoditized. The platforms deliver, but the interesting work is upstream, happening in workshops and internal alignment. Getting the people who own taxonomy to talk to the people who own creative, and to the people who own data feeds. The brands that can connect these different pieces of the puzzle first will be the ones LLMs cite.

Waiting is not a strategy

And we understand the resistance to change: the macro climate is tough, and budgets are tight. The temptation to hold spend and wait out this cycle is real, and we see brands actively considering it. This is the worst available move.

“Waiting is not a strategy. This is happening, and it’s okay. And it’s an exciting time.”

The brands that double down on eligibility now, while competitors wait, will compound advantages. The brands that wait won’t come out of this cycle in the same position they entered it. They’ll come out measurably further behind.

Waiting compounds. Eligibility compounds. Think and act on it before the next budget cycle hits.
