AI Overviews Aren't Taking Your Tire-Kickers. A New Study Says They're Taking Your Best Shoppers.

For two years now, every dealer who watched their blog traffic and their "near me" clicks slide has been handed the same reassurance: don't worry, the traffic you're losing to Google's AI Overviews was never any good anyway. The people who used to click through, the story goes, were tire-kickers, bouncers, and dead-end visitors. AI just filters them out for you and sends you the serious shoppers.

That reassurance came from the top. Google's head of Search, Liz Reid, has publicly argued that AI Overviews send higher-quality clicks and that the visits they eliminate were mostly low-engagement in the first place. It's a comforting message. It lets everyone stop worrying about the number going down.

A new randomized study just tested that claim directly. And it doesn't hold up.

What the study actually found

Two academic researchers — Saharsh Agarwal of the Indian School of Business and Ananya Sen of Carnegie Mellon's Heinz College — ran what they describe as the first randomized field experiment on how AI Overviews change real browsing behavior. The paper, Google AI Overviews and Publisher Traffic: Evidence from a Field Experiment, was posted to SSRN and last revised in June 2026.

This wasn't a survey or a scrape. They built a Chrome extension, recruited 1,065 U.S. participants, and randomly split them into groups for two weeks. One group used Google normally. One had the extension quietly strip AI Overviews out of the results in real time. A third was pushed into Google's AI-first "AI Mode." Then they watched what people actually did. Data collection ran from January 7 to February 10, 2026.

The headline number confirms what you already felt in your own analytics: when an AI Overview appears, outbound clicks to websites drop by 39.8%, and zero-click searches — where the shopper gets their answer and never leaves Google — rise by 34.5%. AI Overviews showed up on roughly 41% of all queries in the study, and on about 53% of informational queries. More on why that last number matters for you in a minute.

But the part that breaks the comfortable narrative is what they found about the clicks that survived versus the clicks that got eaten.

If Google were right — if AI Overviews really do skim off the low-value tire-kickers — then the clicks that still make it through to a website should look better than average: longer visits, fewer instant bounces, more satisfaction. The researchers checked exactly that. They measured back-button returns, quick exits, and time on site across the groups.

There was no meaningful difference. About 4 in 10 clicks bounced straight back to the results page whether or not an AI Overview was present. Roughly 18% of visits ended within 10 seconds in both conditions. Time on site was statistically indistinguishable. And when they surveyed users afterward on satisfaction, information quality, and how easy it was to find what they needed, the differences were what statisticians call "precisely estimated nulls" — a fancy way of saying nothing there, and we're confident it's nothing. Removing AI Overviews, the authors wrote, cost users nothing in how they rated their search experience.

Their conclusion is blunt: the result is "at odds with the view that AIOs primarily eliminate low-engagement website visits." In plain English — the clicks you're losing are just as engaged as the clicks you're keeping. Google isn't filtering out your tire-kickers. It's taking a representative slice of everyone, including your best shoppers.

Why dealers should recognize this movie

If this feels familiar, it should. We have watched Google absorb the click before.

When Google rolled out the local "map pack" and knowledge panels a decade ago, local businesses screamed that Google was stealing their traffic by answering "where's the nearest ___" without sending anyone to a website. They were right that the clicks moved. But the dealers and shops who won that era weren't the ones who fought the panel — they were the ones who owned it, by pouring effort into their Google Business Profile until they were the answer inside the box.

AI Overviews are that same shift, turned up to eleven. The difference is scale and subject. The map pack ate "near me" navigation clicks. AI Overviews eat the research — the whole top of your funnel.

Look at that 53% figure again. AI Overviews trigger most heavily on informational queries. That is precisely the language of a car shopper who hasn't picked a dealer yet:

• "how much should I put down on a car"
• "is a certified pre-owned worth it"
• "0% APR or the rebate — which is better"
• "most reliable midsize SUV under 35k"
• "what credit score do I need to finance a truck"

Those are the questions people ask before they ever search a dealership by name. For years, the smart dealer play was to answer them — with a financing explainer, a trade-in guide, a model-comparison page — earn that early click, and start the relationship before the competition even showed up. That content was your cheapest top-of-funnel salesperson.

This study is telling you two uncomfortable things at once. First, AI Overviews really are intercepting those clicks — the erosion is real, not paranoia. Second, you can't wave it away by telling yourself those were junk visitors. The shopper who would have landed on your financing page and stuck around is now getting Google's summarized answer and moving on, just as engaged as ever — they simply never reach you.

What this means for your dealership

Here's the reframe, and it's the same one that separated the map-pack winners from the losers: stop measuring your top-of-funnel content by the click, and start measuring it by the citation.

If the shopper is going to get their answer inside the AI Overview, your goal is to be the source that answer is built from — with your name attached. AI Overviews and AI Mode stitch their responses out of pages they trust. When your dealership's content is the trusted, clearly-structured source behind "here's how down payments work," the shopper walks away with your name in their head even if they didn't click. That's not a lost visit. That's a branded impression you used to pay for.

The clicks you do still get are also more precious than ever, which raises the stakes on what happens after the shopper lands. If AI Overviews are thinning the top of your funnel, a slow, cluttered, hard-to-navigate site that leaks the survivors is no longer a minor problem. It's the whole game.

What to do about it

• Audit which of your informational pages sit behind an AI Overview. Google your own top research questions — financing, trade-in, CPO, model comparisons — and see where AI answers before your link. Those are the pages to restructure for citation, not the ones to abandon.
• Write for the machine that summarizes, not just the human that skims. Clear questions as headers, direct answers underneath, structured data, no burying the fact under three paragraphs of fluff. AI Overviews lift clean, unambiguous answers. Give them yours, with your dealership named in it.
• Stop grading blog and education content on raw sessions alone. If traffic to a genuinely useful page is down but the topic is one AI now answers, you may be winning the impression and losing the click — that's a branding gain, not a failure. Measure assisted conversions and branded search lift, not just pageviews.
• Protect the clicks that survive. Speed, clarity, and a frictionless path to a lead form or a phone call matter more now that each visit is harder-won. Fix the leaks before you chase more traffic.
• Own your Google Business Profile like it's your homepage. The same shopper the AI Overview intercepts still checks the map pack before choosing where to go. That box is one place you can still control the answer.

The dealers who lose the next two years will be the ones who believed the comforting story — that the traffic slipping away was never worth having. This study is the receipt that says otherwise. The clicks AI is taking are your real shoppers. The winners won't be the ones who fight to claw those clicks back. They'll be the ones who make sure that when the AI answers the question, it answers it with their name on it — and that the shoppers who still come through the door don't slip out the back.
