Check One Number in Your Google Ads Before August 17
If you run Google Ads, there’s a number sitting in your account that probably hasn’t been questioned in years. It’s your target — the cost per lead, or the return on ad spend, that Google has been told you’re willing to accept. Plenty of owners never set it themselves. An agency did, or it came out of the setup flow when the campaign was built.
Here’s the part worth knowing. Some campaigns have been doing considerably better than that number. You may have told Google that a $10 lead was acceptable while it kept finding them for $5, and pocketed the difference without ever knowing there was a difference to pocket.
On August 17, Google starts steering those campaigns closer to the number you entered.
What that costs is worth being precise about, because it’s easy to get wrong. A campaign marked “Limited by budget” spends its budget either way — that’s what the label means. So you won’t see a bigger bill. A campaign finding leads at $5 against a $10 target and bringing in 100 leads a month delivers closer to 50 once it optimizes toward $10. The spend stays where it was, and the number of customers it buys you is what falls.
So the figure nobody has looked at could become the figure you actually pay. You have eighteen days to check it, and checking takes about twenty minutes.
Why It Matters
Three things have to be true for this to affect you. The campaign has to be marked “Limited by budget.” It has to use Target CPA or Target ROAS bidding. And it has to currently be beating that target. Miss any one of those and today’s issue isn’t about you.
If all three are true, Google’s own documentation is direct about what happens. Campaigns limited by budget using a target-based bid strategy will more consistently perform toward your bid target, including when you make budget adjustments. Their example: a campaign with a Target CPA of $10 that’s been achieving $5 will deliver closer to $10 starting August 17.
The number nobody questioned is about to become the number you actually pay.
Two details that matter more than they look. Google has said plainly it will not adjust your targets or budgets for you — the change happens automatically, the preparation does not. And the notifications went out in early July to any advertiser with a campaign that was limited by budget at any point in the past twelve months, which is a wider net than your account’s status today.
There’s a genuine upside in here too, and it’s worth naming. Before this change, raising the daily budget on one of these campaigns often produced erratic results — performance would swing, sometimes downward, for reasons nobody could explain. After August 17, Google says campaigns will optimize consistently toward your target regardless of the budget limit. If you’ve been reluctant to increase spend because the last time you tried it went sideways, this is the change that fixes that.

Who This Affects
The transition covers Search, Shopping, Performance Max, Demand Gen and Travel campaigns. Display and Hotel campaigns already run the new behavior, so nothing changes for them on the 17th. App campaigns, Video reach and Video view campaigns continue on the previous behavior and are unaffected entirely.
And the size of the effect depends on how far your actual results have drifted from your stated target. If they’re close together, the change is small. The dramatic cases are accounts where the target was set once, generously, and never revisited.
The Backdrop
This arrives in an auction that was already expensive.
| Measure | Where it stands |
|---|---|
| Average US search click | $5.42 |
| Average US cost per lead | Down for the first time since 2020 |
| Click costs, Shopping & Performance Max | Up 15% year over year |
| Return on ad spend, Performance Max | Down 46% |
The click and lead figures come from LocaliQ’s 2026 benchmark; the other two from Channable’s analysis of €1.38 billion in verified spend across more than 10,000 advertisers, which covers European e-commerce rather than American service businesses.
Notice that the second row complicates the first. Clicks got more expensive while the average lead got slightly cheaper, which is a reminder that broad benchmarks describe a market rather than your account. Yours may be running against the trend in either direction.
The Owner’s Forecast
I’ve marked this high because it isn’t a prediction about where the market is heading. It’s a dated change published in Google’s own help documentation, with a tool built specifically to help people prepare for it. The only real uncertainty is how many accounts are affected and by how much.
What I expect through the autumn: owners noticing in September that their cost per customer climbed, blaming the ad copy or the agency, and never connecting it to a setting last touched years ago. Twenty minutes this week keeps you out of that group.
The longer thread underneath is worth watching. Each of these changes moves more of the decision-making inside Google’s systems and asks you for better information in return. That trade keeps getting offered, and it keeps rewarding the advertiser who knows what a customer is genuinely worth to them rather than accepting whatever number the platform has been delivering.
Your Next Move
Good — 5 minutes. Open Google Ads and look at your campaigns. Any showing “Limited by budget”? Any running Target CPA or Target ROAS? If either answer is no, you’re finished and you can go back to your morning.
Better — 20 minutes. If you are affected, open the Bid Target Adjustment Tool in your account. It shows which campaigns are exposed alongside what each has actually delivered recently. Google’s guidance is that lowering your target to match recent performance keeps your results close to where they’ve been, and you can raise the budget later. Do it before the 17th.
Best — ongoing. Set your target from your own arithmetic rather than from whatever Google has been handing you. What is a customer worth to you over a year? What can you pay to get one and still make money? A target built from that survives every platform change, because it was never borrowed from the platform to begin with.
Today’s Instrument
Google’s Bid Target Adjustment Tool
Free, and already sitting in your account
It went live on July 6 and exists for exactly this. It identifies which of your campaigns are limited by budget and running target-based bidding, shows your set target beside your actual recent performance, and lets you apply the update in a couple of clicks. If your account was flagged, a notification in Google Ads points you straight to it.
- Best for
- Anyone with a budget-limited campaign on Target CPA or Target ROAS. Which is most small advertisers, whether or not they know it.
- Skip if
- Your current targets already reflect what you can afford to pay. Google’s position is that no action is needed in that case, and that’s correct.
Almanac note: we earn nothing from today’s recommendation. It’s free, it’s already in your account, and it’s the right tool for this week.
A note: this bumped the review-request piece we promised yesterday. Deadlines win. That one runs tomorrow.
Owners Are Asking
How do I know whether I’m affected?
Look for two things together: a campaign with “Limited by budget” status, and a bid strategy of Target CPA or Target ROAS. Then check whether that campaign has been delivering better than its target. All three, or it doesn’t apply to you.
Will Google fix my targets for me?
No. Google has stated it will not adjust targets or budgets automatically. If your current target reflects what you want to pay, no action is needed.
What if I switch to Maximize Conversions instead?
That’s one of the options Google lists, and it sidesteps the change. The trade is that strategies without a target spend your full budget and let your cost per conversion move around. You’d be swapping an enforced number for an unpredictable one.
Is Google raising ad prices?
Not directly. What a click costs at auction isn’t changing. What’s changing is how closely campaigns are steered toward the target you set, which for accounts that were beating their target has a similar effect on the invoice.
