On July 12, Channable published one of the largest Google Ads benchmarks anyone has released this year: €1.38 billion in verified spend across more than 10,000 e-commerce advertisers. The headline is blunt. Between June 2025 and June 2026, the average cost per click rose 15%. Over the same twelve months, the average return on ad spend fell 46% on Performance Max and 43% on Standard Shopping.
Read that again slowly: the same click costs more and earns less. Cost per acquisition rose on every campaign type in the study. This isn't one bad account or one bad month — it's the median across ten thousand businesses.
The US picture rhymes. WordStream's 2026 benchmark, covering 13,000+ American campaigns, put the average search cost per click at $5.42. So if your ads "used to work" and now feel like they're treading water, the data says you're not imagining it — and you're not alone.
Why the click got more expensive
Channable points at three forces. First, more advertisers are entering the same auctions, which raises the floor price for everyone. Second, Performance Max — Google's do-it-all automated campaign type — pools Search, Display, YouTube, Gmail, and Maps into one auction, concentrating competition that used to be spread out. Third, and this is the part you can actually control: a widening gap between advertisers who feed Google clean, complete product data and those who don't.
That last one matters because Google's AI bids on your behalf using whatever information you give it. Incomplete listings, wrong categories, missing attributes — the algorithm compensates by making you pay more for the same visibility. Channable's co-founder put the distinction simply: the 15% increase is painful if you're running the same messy setup as last year, and manageable if your product data is doing its share of the work.
Your ad account stopped being a budget line. It's now data infrastructure — and it pays back exactly what you feed it.
The August 17 deadline most owners haven't heard about
There's a second cost wave coming, and this one has a date on it. On August 17, Google changes how budget-limited campaigns using Target CPA or Target ROAS bidding behave. Today, plenty of campaigns quietly convert well below the target you typed in months ago. After the change, those campaigns will drift toward your stated target — which for some advertisers means costs rising toward a number they set carelessly and forgot.
Google shipped a Bid Target Adjustment Tool on July 6 to let you review and fix your targets before the switch flips. That's the 20-minute check: open your campaigns, compare what you're actually paying per conversion against the target you told Google you'd accept, and close the gap on anything where the stated number is way above reality. Do it before August 17, not after the bill arrives.
What to do with the rest of the year
Budget Q4 like it costs more, because it does. In Channable's data, fourth-quarter ad spend ran 47.9% higher than Q1, and clicks cost 9.1% more. A budget calibrated to spring competition will run out in November.
Fix the feed before you raise the bid. If you sell products, your titles, categories, images, and attributes are now a bigger lever than your bid strategy. An hour with an AI assistant reviewing your product feed against Google's requirements is one of the highest-return marketing hours available this quarter.
Stop treating "automated" as "unattended." Performance Max will happily spend whatever you give it. The owners absorbing this increase best aren't the ones who opted out of automation — they're the ones who check the numbers monthly and feed the machine better inputs than their competitors do.
Rising click costs aren't a reason to abandon paid ads. They're a reason to stop running them on autopilot with last year's settings. The gap between advertisers who tend the machine and advertisers who just pay it is widening — the only question is which side of it you're on by Q4.
