Every few years paid search goes through a period where the numbers stop making intuitive sense, and agencies spend a quarter or two arguing about whether it is a blip or a structural shift before conceding it was structural all along. That is roughly where the industry sits right now. Cost-per-click on Google Ads rose 15 percent year over year between June 2025 and June 2026, according to a benchmark from the Dutch ecommerce platform Channable, built on 1.38 billion euros of verified ad spend across more than ten thousand advertisers. Shopping and Performance Max campaigns saw the same 15 percent jump. And the number that should actually worry people sits right next to it: return on ad spend fell more than 40 percent over the same period. Advertisers are paying more per click and getting meaningfully less back for the money, and those two facts together are the whole story.
What is actually happening to organic search
To understand why, it helps to separate two things that are happening at once and reinforcing each other. The first is what is happening to organic search. AI Overviews, the generated summaries Google now shows above traditional results, are no longer a minor feature living on the edge of a small number of queries. By March 2026 they were appearing on somewhere between a quarter and roughly half of all searches, depending on the query set measured, and that share is still climbing. A large field study covering January and February 2026 found that when an AI Overview appears, outbound organic clicks fall by 38 percent, and the share of searches ending with no click at all rose from 54 percent to 72 percent. Seer Interactive's independent research, tracking a longer window from January 2025 through February 2026, found organic click-through on AI Overview queries dropped from 1.76 percent to 0.61 percent, a 61 percent decline. Read those numbers plainly: for a huge and growing share of searches, the organic listing that used to be a business's free front door now gets seen by a shrinking fraction of the people who used to walk through it.
That would be a traffic story on its own, but it becomes a pricing story because of where advertisers go next. When the free channel stops converting the way it used to, the instinct, and for a lot of businesses the necessity, is to buy the visibility they can no longer earn. That pushes more budget and more advertisers into paid inventory that Google has, by design, arranged to sit above or beside the AI-generated answer. Fewer people are clicking anything, but more advertisers are competing for the smaller number of clicks that remain, and in an auction system that is close to the textbook definition of what drives price up.
Navigate Rising CPCs with an AI-Driven PPC Strategy
The automation feedback loop
The second force compounding this is automation, and it is subtler because it looks like a convenience rather than a cost driver. Performance Max and Smart Bidding have made it dramatically easier for small and mid-size businesses to run a competent paid search campaign without a dedicated specialist, which sounds like democratization and mostly is. But it also means more advertisers, in more categories, are now bidding in the same auctions who previously would not have bothered. And because Smart Bidding strategies like Maximize Conversions and Target ROAS are all, across every advertiser using them, optimizing toward the same objective, the algorithms end up collectively pushing each other toward the ceiling of what each advertiser is willing to pay. Nobody set out to bid up the market. It is an emergent property of everyone using the same automated tool to chase the same outcome in the same limited pool of high-intent inventory. The industries seeing the steepest CPC increases this year, legal services up 14 percent, home improvement up 13 percent, B2B up 12 percent, per WordStream and LocaliQ's Q1 2026 industry benchmarks, are also the categories where advertisers report the heaviest push into Performance Max, a pattern that lines up closely.
The one bright spot: citation lift
There is one more wrinkle worth understanding because it complicates the doom narrative slightly: being cited inside an AI Overview is not pure loss. Brands that get named or linked within an Overview see 35 percent more organic clicks and 91 percent more paid clicks than brands the Overview does not mention. That is a meaningful incentive shift. Bidding smarter still matters, but increasingly the bigger lever is the content and structure of what a brand publishes, its odds of being the source an AI Overview decides to cite in the first place, because visibility inside the answer is turning into its own kind of premium inventory, separate from and upstream of the paid auction.
Why the old pricing model breaks
Put the pieces together and the plan an agency built in 2023 does not really work anymore. The strategy was sound at the time. The terrain underneath it has simply moved. A media plan priced on last year's CPC and last year's expected ROAS is going to miss its numbers this year almost by default, and clients are going to notice before the agency does if the pricing model was not built to move with the data. This is where the harder conversation has to happen, because the honest fix runs deeper than adjusting bids. It requires changing the pricing model itself. A meaningful share of agencies, industry pricing surveys put the figure somewhere between roughly a third and two out of five, have already moved at least one service line away from flat retainers and toward pricing structures with a performance component built in, tying at least part of agency compensation to outcomes rather than hours or ad spend under management. The exact number varies by survey and none of them is a definitive, independently audited census of the industry, but the direction is consistent everywhere it has been measured. That shift did not happen because agencies suddenly discovered a love of risk. It happened because flat retainers built on stable, predictable CPCs stop making sense the moment CPCs are moving 15 percent in a year while ROAS is falling twice that fast. A client paying the same management fee for a plan that now returns 40 percent less is going to ask hard questions, and an agency without an answer built into the pricing itself is going to lose the account before it gets the chance to explain the macro trend.
What belongs in this year's renewal conversation
Practically, this means a few things belong in every renewal conversation this year rather than next. Media plans need rebuilding around current auction dynamics, because the 2025 baseline a lot of plans are still quietly anchored to is already out of date. Budget needs to move deliberately toward the categories and formats where being cited or ranked well inside an AI Overview creates that 35 to 91 percent lift, because that is becoming its own channel, with a return curve unlike traditional SEO or paid search. And retainer structures need an honest look, because a fee model that assumes stable CPCs is now built on sand, and clients will eventually notice that the agency's revenue stayed flat while their return on spend did not.
This is the market resetting itself around a search experience that increasingly does not send anyone anywhere. Agencies that reprice around that reality now will be negotiating from having called it early, instead of scrambling later to explain why the numbers stopped adding up.
