AI search is walling off organic traffic before it reaches you, and the reflex is to buy more of it. That is the wrong move. When each visit is scarcer and dearer, the money is in the shopfront you already have, not the top of the funnel.
The number that pays your bills is not how many people walk in. It's how many walk out with a purchase.
I sat on the client side for years watching agencies pitch more traffic as the answer to every problem. Then I sat on the agency side and watched us do the same thing, because more traffic is easy to sell and easy to bill. Here's the thing nobody in that room wanted to say out loud. Most of those businesses didn't have a traffic problem. They had a shopfront that was quietly bleeding out, and pouring more people through the front door just made the leak bigger.
That's the argument. As AI search eats your organic traffic, the reflex is to go and buy more of it to replace what you lost. It's the wrong move. The traffic you already get is where the money is. The shopfront is where the money is. Right now most Australian businesses are paying to fill a shopfront they never bothered to fix.
The traffic you had is being taken at the door
Let's be clear about what's actually happening, because it's worse than most owners think. Ahrefs looked at 300,000 keywords and found that when Google shows an AI Overview, the average click-through rate for the top organic result dropped 34.5%. The position one CTR fell from 0.073 to 0.026 year on year. That's the best position on the page losing more than a third of its clicks. When they re-ran the study for 2026, the reduction had grown to 58%.
Now stack the local picture on top. In Australia, roughly 58% of searches now end without a single click, up from about 51% in 2023. When Google serves an AI-generated summary, only about 8% of those searches lead to a link click, versus about 15% without one. The answer gets resolved on the results page and the visit never arrives.

So the visit is getting scarcer. What does the market do in response? It bids harder for what's left. Australian ad spend is forecast to grow about 6.5% in 2026 to around $30.7 billion. More money chasing the same or fewer clicks. You don't need a finance degree to see where that goes. Your cost per visit climbs, and the visit is worth exactly the same as it was before, which is nothing until it converts.
A thousand people walk in. How many walk out with a purchase?
Your website is your shopfront. If a thousand people walk in, how many walk out with a purchase? Most owners can't tell you. They know how many walked in, because that number is easy and it feels like progress. The number that matters is the one they never look at.
This is what we see again and again when we measure the Australian market. Conversion is one of the weakest dimensions across the board. Businesses over-invest at the top of the funnel and under-invest in the shopfront. They'll spend hand over fist getting people to the door and then leave the door half shut.
Run the maths a physical retailer would run without thinking. A shop counts the people who come through the door, watches the security footage, checks the till at the end of the day and works out its conversion rate. It's built in. The digital version has to be intentional about it, and most aren't. So they're flying blind on the exact number that decides whether the business makes money.
Here's the part that should sting. If each visit is now scarcer and more expensive, the conversion rate isn't a nice-to-have. It's the whole game. Doubling your traffic when your shopfront converts at 1% just doubles the number of people who leave empty-handed. Fixing the shopfront so it converts at 2% doubles your revenue off the traffic you already paid for.
Mobile is where the money is leaking
If you want to know where the leak is, look at your device split first. Mobile carries the majority of traffic for most businesses now, and it converts far worse than desktop. The 2026 benchmarks put desktop ecommerce conversion around 3 to 4.5% and mobile around 1.5 to 3%. Most of your visitors are on the worse-performing device, on a shopfront that was probably designed and signed off on a desktop screen.
That gap is not a rounding error. That's revenue walking out the door on a phone that took too long to load, a form that was a pain to fill in, a checkout that fought the customer at the last step. I've seen businesses fix their website and go to a plus 20% of revenue overnight, because their mobile experience was that bad and nobody had looked.
Nobody had looked. That's the whole story. You can't fix what you refuse to measure, and you can't measure what you've decided you already understand.
What I'd do about it
Stop the reflex first. Before you spend another dollar buying visits to replace the ones AI search took, look at what happens to the visits you already get. That's the cheapest revenue in the building because you've already paid for the traffic.
Do you know how much money you make? Do you know how much money you spend? We can work back from there. Start with three numbers. How many people land on your shopfront. How many take the action that matters. What that gap is worth in revenue. Then slice it by device, because that's usually where the leak is hiding.
Once you can see the gap, fix the shopfront in the order that pays. Speed on mobile. The checkout or the enquiry form. The single page most of your traffic lands on. These aren't glamorous jobs and they don't make a good slide in a pitch deck. They just make money.
Then, and only then, think about traffic. Paid search still has a place. In a world where AI Overviews sit above the organic results, a paid position is one of the few spots you can actually control. But paid traffic into a broken shopfront is the fastest way to turn a leak into a haemorrhage. Fix the shopfront, then turn the tap on. Not the other way around.
The businesses that win from here
The businesses that come out of this ahead won't be the ones who spent the most to replace their lost clicks. They'll be the ones who worked out that a scarcer, dearer visit is worth more, not less, and treated it that way.
When every visit costs more and there are fewer of them to go around, the sloppy shopfront stops being a minor inefficiency and becomes the thing that decides whether you make money. The market is about to sort businesses into two groups. The ones still buying traffic to paper over a broken shopfront, and the ones converting the traffic they've already got.
Go and count the people walking out of yours. That number is the business.
