Key Takeaways
- What’s actually changing: From 17 August 2026, budget-limited campaigns using Target CPA or Target ROAS will start tracking more closely to the actual targets entered, even after budget changes.
- Which campaigns to check: Search, Shopping, Performance Max, Demand Gen, and Travel campaigns marked “Limited by budget” are affected, especially those already beating their targets.
- Why it matters most for strong performers: Targets set months ago may no longer reflect improved performance, so overperforming campaigns risk drifting back toward outdated numbers.
- What to check before August: Review budget-limited campaigns, compare actual performance against targets, and confirm the numbers still match current business goals.
- Other updates worth knowing: Smart Bidding Exploration is now global, and Promotion mode is in beta, but the budget-limited change should be reviewed first.
- How Amire can help: Amire can identify affected campaigns, compare performance against targets, and help decide whether to keep, adjust, or test new bidding strategies.
Google is making a change to how some bidding strategies work, and it’s worth a look before it affects your campaigns. From 17 August 2026, if your campaign uses Target CPA or Target ROAS and is marked “Limited by budget”, it may start performing closer to the actual target number you’ve set, even when you increase your budget.
The simplest way to think about it: are your current targets still right for your business today?
What’s Actually Changing?
Right now, some budget-limited campaigns can outperform their own targets. If you set a Target CPA of $80 but your campaign has been winning leads at $50, that gap can grow or shrink unpredictably whenever you change the budget.
From 17 August, Google wants the performance to track more closely to whatever number you’ve actually entered. So using the same example, a campaign with an $80 target that’s been running at $50 may start drifting back up toward $80.
This doesn’t mean you need to rebuild your account. It does mean it’s worth checking whether the targets sitting in your account still make sense. A number you set six months ago might not match your margins or goals today.
Which Campaigns Should You Check?
This applies to campaigns marked “Limited by budget” using Target CPA, Target ROAS, or a similar target-based strategy. It covers Search, Shopping, Performance Max, Demand Gen, and Travel campaigns. If you run Performance Max or Demand Gen, you might also see some shift in how traffic spreads across channels.
The accounts that should look closest are the ones where campaigns have been beating their targets, where you’re planning to increase budget soon, or where a stable, predictable cost per lead really matters to the business.
Why This Matters Most For Campaigns That Are Doing Well
Here’s the thing. This update isn’t really about Google tightening the screws. It’s about old targets that were never updated as performance improved.
Say you set a Target CPA of $100 a while back. Since then, your landing pages got better, your tracking got cleaner, your ads got sharper, and your actual CPA dropped to $65. If that target was never touched, Google has effectively been working off a number that doesn’t reflect what you actually care about protecting.
If $100 is genuinely fine for you, because you want to grow volume and you’re comfortable spending more per lead to get there, leave it. But if $65 is the number you want to hold onto, it’s worth updating the target before August.
This is really a business decision, not just a technical one. The right CPA or ROAS depends on your margins, how good your leads are, your close rate, and what you’re trying to grow. Cheaper isn’t always better if it caps your volume too much, and a higher cost isn’t a problem if the growth it buys is profitable.
What To Check Before 17 August
Google is rolling out a Bid Target Adjustment Tool inside Google Ads from 6 July 2026. It shows your historical performance and lets you update targets in a couple of clicks, so you don’t need to go digging through reports manually.
Before then, it’s worth running through a few things:
- Find your budget-limited campaigns: Which ones have recently shown a “Limited by budget” status?
- Check the bid strategy: Are they using Target CPA, Target ROAS, or something else target-based?
- Compare target versus reality: What’s your actual recent CPA or ROAS compared to what’s set in the account?
- Revisit your goals: Does the target still match your margins and what you’re trying to achieve?
- Think about upcoming budget changes: Are any of these campaigns getting more budget soon, especially the ones overperforming?
- Look at lead quality: Make sure your targets are built on real conversions, not just soft form fills.
Once you’ve gone through this, you’ve really got a few options. Keep the target as is, update it to match recent performance, set a custom number, switch bid strategy entirely, or increase your budget with more confidence now that performance should hold steadier.
A Couple Of Other Updates Worth Knowing About
This change is part of a wider set of bidding updates Google announced. Search Engine Journal reported on two others alongside it: Smart Bidding Exploration is now available everywhere, and a new Promotion mode is in beta.
Smart Bidding Exploration helps find extra converting traffic outside your usual targets, which could be useful if you’re feeling boxed in on volume. Promotion mode, currently in beta for Search and Performance Max, gives you more flexibility around short bursts like a seasonal sale or product launch, without having to manually juggle budgets and targets yourself.
Both are optional, so there’s no rush. The budget-limited campaign change is the one to prioritise, since it will affect your account whether you opt into anything or not.
How Amire Can Help You Prepare For The Update
Knowing that Google Ads is changing is one thing. Knowing whether it actually affects your account, and what to do about it, is the harder part.
We’ve been running Search Engine Marketing campaigns since 2002, and we know a target only works if it’s still tied to your real numbers, your margins, and what each campaign is actually meant to achieve.
If you run Google Ads and you’re not sure whether this update touches your campaigns, we’re happy to take a look. We can flag which campaigns are affected, check your recent performance against your stated targets, and help you decide whether to keep things as they are, adjust, or try something new with confidence.
