Your Google Ads Got More Expensive and Nobody Changed Anything
If your Google Ads campaign runs on a tight daily budget and your cost per click — what you pay each time someone clicks your ad — has crept up since mid-August, it may not have been anything you or your ad manager did. Google changed how bidding works for budget-capped campaigns, and early data from a large e-commerce ad dataset points at who's paying for it: the advertisers whose budgets run out first.
Here's what changed, in plain English, and the four realistic ways to respond.

What Google changed on August 17
On August 17, 2026, Google updated its bidding systems for campaigns that use a target-based bid strategy — Target CPA (you tell Google what a lead should cost) or Target ROAS (you tell Google what return you want per dollar of ad spend). The change applies to Search, Shopping, Performance Max, and Demand Gen campaigns, and finished rolling out on August 27.
Google's framing was that budget-limited campaigns will now "more consistently perform toward your target." Here's the translation. Before this update, when a campaign hit its budget cap, Google quietly held bids down — which often meant those campaigns beat the target you'd set and picked up cheaper-than-expected clicks. Google considered that unpredictable. The update ended that bid suppression: capped campaigns now bid at your stated target, not below it.
Less predictably cheap, more predictably on-target. Whether that's an upgrade depends entirely on which side of the change your account sits.
What "limited by budget" actually means
"Limited by budget" is a status Google shows on a campaign when your daily budget runs out before the day's available demand does — there were more relevant searches than your budget could buy. You can see it in the Status column of your campaigns table in Google Ads.
Lots of small-business campaigns live in this state permanently, and until August, it came with a hidden consolation prize: those suppressed bids meant capped campaigns often paid less per click than their settings implied. That consolation prize is what just went away.
What the data shows a month later
Mike Ryan of Smarter Ecommerce published early data on the update's effects, covered by Search Engine Roundtable. It's one analysis, drawn from e-commerce accounts, so treat it as a first read rather than the final word — but it's the clearest data anyone has shared so far, and it shows two things:
Cost per click is rising for budget-limited campaigns. With bid suppression gone, capped campaigns bid at their full target — and pay accordingly. Median CPCs for limited-by-budget campaigns diverged upward after August 17.
The cheap clicks didn't disappear — they moved. The pool of inexpensive clicks that suppressed bidding used to win has been freed up, and it's now going to campaigns that aren't budget-limited. When another PPC practitioner asked whether this means Google improved the system for everyone except the budget-limited accounts, the answer from the reporting was: yes, that's the correct read.
That second point is the one worth sitting with. This wasn't a price increase across the board. It was a transfer — from advertisers running capped budgets to advertisers who aren't.
What this means for a small budget
If your campaign runs uncapped, the early data suggests you may benefit: the cheap clicks that capped campaigns used to absorb are now available to you.
If your campaign runs capped — a common state for small budgets, where the daily budget often runs out before the day's searches do — expect fewer clicks for the same spend, at a cost per click closer to the target you set. Your results aren't necessarily worse: you told Google what a lead is worth to you, and Google is now taking you at your word. But the era of quietly outperforming your own target while capped is over.
The wrong response is panic. The worse response is not noticing. A budget that made sense under the old bidding math may not be the right number under the new one — and that's a decision, not an accident.
4 Ways to Respond
1. Check whether this even applies to you
Open Google Ads, look at the Status column. No "Limited by budget" label and no target-based bid strategy means this update largely isn't your problem. (While you're in there, this pairs well with a check of what still limits your ad costs after this year's other bidding changes.)
2. Right-size the budget instead of running capped
Google's system now works best when budget and target agree with each other. If the campaign is producing leads at an acceptable cost, funding it fully — so it's no longer budget-limited — puts you on the side of the change that's collecting the cheap clicks instead of surrendering them. Only do this if the math already works; a bigger budget on a campaign that isn't converting just loses money faster.
3. Adjust the target to match reality
If raising budget isn't on the table, loosen the target instead. A Target CPA set optimistically low used to be papered over by bid suppression; now it constrains what Google will bid on. Set the target at what a lead is genuinely worth to you — your close rate and average sale value tell you that number, not the platform.
4. Concentrate
Two capped campaigns are now worse than one funded campaign. If your budget is spread across several campaigns that are all limited, consolidating into fewer campaigns that run uncapped fits how the system now rewards spend. One platform, one campaign, done well — the same logic as choosing between Google and Meta in the first place.
How this should show up in your reporting
If someone manages your ads, your next monthly report should name this. Something like: "CPC rose X% starting mid-August. That's Google's August 17 bidding update, not a change we made — here's what we're doing about it." Then one of the four moves above, with a reason.
What you shouldn't accept is a report where costs moved and nobody explains why. Platform changes like this are exactly the kind of thing an ad manager should surface before you notice it — it's their job to know why the numbers moved, even when the answer is "Google."
