Google Ads · Deadline: 17 August 2026
Google’s swearing blind that the bidding change landing on 17 August 2026 is exactly as small as the docs say. The PPC community isn’t buying it. And there’s a separate curveball for anyone running home services ads.
Let’s sort out what’s real, what’s suspicion, and what you need to do before the deadline.
From 17 August, budget-limited campaigns on Target CPA or Target ROAS will start chasing the number you typed in — not the better number they’ve been quietly delivering. If your stated target is looser than your real performance, that gap closes. On you.
What’s actually changing
Right now, if you’ve got a campaign with a Target CPA of $10 that’s quietly been converting at $5, Google lets you keep that gap as a bonus. The stated target is loose. The system beats it, and you pocket the difference.
After 17 August, that stops. Per Google’s Help Center article “Changes to target based bid strategies”, quoted by Search Engine Roundtable via PPC Land, the same $10 campaign will start drifting toward the $10 you actually typed in. The number you set becomes the number the system chases.
Target ROAS works the same way in reverse. Set a campaign to 200% return that’s been quietly delivering 400%, and it’ll settle back toward 200 after the change.
Google isn’t touching your settings. Nobody’s going into your account and editing figures. The stated number just starts to bind, whether it’s a live business goal or something you typed in eighteen months ago and forgot about.
“Limited by budget” is a status Google slaps on a campaign when it wants to spend more than your daily budget allows. That status is the trigger here.
Who’s affected
| Campaign type | Impact |
|---|---|
| Search, Shopping, Performance Max, Demand Gen, Travel | Affected — if “Limited by budget” while running Target CPA or Target ROAS |
| Hotel, Display | Already run on the new logic — nothing shifts |
| App, Video reach, Video view | Outside the update completely |

And it’s not just the main interface. Search Ads 360, Display & Video 360, Google Ads Editor, and the Google Ads API all inherit the change. A separate notice gave Demand Gen line items inside DV360 the same 17 August deadline. So if your agency audit only checks one console, you’ll miss exposed targets sitting in the others.
Why Google says it changed — and what practitioners reckon
Google’s line
Ginny Marvin, the Google Ads Liaison, addressed this directly on LinkedIn. Her line was that they’re making the controls clearer, and that the update only affects budget-constrained campaigns using a target because unconstrained campaigns already behave this way. Performance in budget-limited campaigns has been fluctuating unexpectedly when budgets change, and removing that inconsistency is the whole point.
The community’s read
The thread that kicked this off came from Joey Bidner, a freelance Google Ads consultant, who said he’d never been more frustrated by a Google Ads update. His argument wasn’t confusion — it was deliberate practice. Some of his best accounts run intentionally loose Target ROAS or high Target CPA settings on purpose, because loose targets give Smart Bidding room to explore new customers instead of just remarketing to reliable ones. Honour those stated targets strictly, and the system chases the number on the page rather than the efficiency the account actually hits.
That’s the crux. Both readings survive contact with the docs, because both are technically true.
Greg Finn of Cypress North, talking to Barry Schwartz, forecast rising cost-per-click figures. His logic is hard to argue with: stated acquisition costs can’t climb without something in the auction climbing alongside them.
Marvin pushed back on the money worry. She said the update by itself won’t change spend on any campaign, including ones already capped by budget, and that if you lower a target to match your current average delivery while leaving the budget alone, the campaign should keep performing as it does now.
That didn’t settle it. Other commenters made a fair point about transparency: if Smart Bidding behaves differently depending on budget constraints and target settings, those shifts belong in visible account data, not buried in notification emails and a recommendation tool.
My honest read? Google’s narrow-technical framing is probably accurate on the letter of it. But six weeks of notice for a change that can effectively double a working CPA target is thin, and the suspicion that this quietly hoovers up unclaimed efficiency across the auction isn’t paranoid. It’s arithmetic.
How this hits a typical account
Say you run a lead-gen account with a Target CPA of $40 on your best Search campaign, and it’s been delivering $22 leads while capped by budget. Today you’re getting cheap leads and banking the gap. After 17 August, that campaign drifts toward $40 a lead. Same budget, fewer leads at a higher cost each, because the system is now allowed to spend up to the number you told it was acceptable.
The volume you lose doesn’t vanish into thin air. One commenter predicted the roughly 10 to 15% of advertisers who refuse to adopt new targets get squeezed out, with their conversion volume redistributed across everyone who stays. Read that how you like.
If your targets already reflect your real goals and your campaigns aren’t budget-limited, you’ll likely feel nothing. This bites hardest on accounts running loose targets as a deliberate tactic.
How to check whether you’re exposed
- Look for the notification. Open Google Ads and look for a notification about the Bid Target Adjustment Tool. It appeared in accounts on 6 July 2026, triggered for any advertiser whose campaigns carried a “Limited by budget” status at any point in the previous twelve months while running an affected strategy.
- Filter your campaigns. If you didn’t get the notification, go to your Campaigns view and add the “Status” column. Filter for campaigns showing “Limited by budget”.
- Check the bid strategy. You’re looking for Target CPA or Target ROAS. Maximize Conversions and Maximize Conversion Value without a target aren’t affected.
- Compare target vs delivery. For every affected campaign, compare the stated target against actual recent delivery. If your Target CPA says $40 and you’ve been getting $22 leads, that’s a gap that’s about to close on you.
- Repeat everywhere. Run the whole check in Search Ads 360, DV360, and via the API if you use them. One console won’t show you everything.
How to verify behaviour after the change
After 17 August, watch your CPA and ROAS on the campaigns you flagged. Track average cost-per-lead or ROAS day by day around the date, and note whether spend and volume shift while your budget stays put. If Marvin’s assurance holds, campaigns where you’ve matched target to delivery should stay flat. Keeping budget and bidding behaviour under proper watch through that window is exactly what CLICC‘s Budget Intelligence is built for, so you’re not squinting at a notification email hoping for the best.
What to do, in order
Inside the Bid Target Adjustment Tool you get three paths: keep the existing target and accept the drift, lower the target to match recent delivery and hold your current efficiency, or enter a custom figure in between. A fourth option is switching to Maximize Conversions or Maximize Conversion Value, which drops the target constraint entirely and trades a fixed efficiency figure for volume within budget.
Option two. Lower the target to match what you’re actually delivering, leave the budget alone. Do it before 17 August, not after.
Google has said flatly it will not adjust anyone’s targets or budgets automatically. Every decision, and every consequence of not deciding, sits with you.
Four weeks remain from the article’s window. Don’t let this one drift.
One more thing if you run home services
Apple published a policy on 14 July 2026 for a Maps advertising product that hasn’t launched yet, and per PPC Land’s coverage of MediaPost’s reporting, it bans home services businesses outright. That’s plumbing, electrical, locksmiths, HVAC, pest control, roofing, and general contracting.
The deeper restriction: Maps ads will be limited to places with a physical address, which cuts out the dispatch-based local services model that Google and Yelp make money from. The prohibited list also covers alcohol, dating, contests and sweepstakes, gambling, religion, bail bonds, cryptocurrency ATMs, and medical services.
The practical upshot is small for now, because the product doesn’t exist yet. But if you or a client had been eyeing Apple Maps as a future channel for a plumbing or HVAC business, cross it off. Apple’s told you the door’s shut before it ever opened.
