Since August 17, 2026, a Google Ads Target CPA or Target ROAS is a real target, not a ceiling. Google’s Help Center says budget-limited campaigns now "perform more consistently towards your bid target," so a $10 target that delivered $5 leads will drift toward $10. If your cost per lead rose recently, lower the target to your real numbers.
What exactly did Google change on August 17?
Google changed how Smart Bidding treats a target on any campaign that is spending its full daily budget. Before, Target CPA and Target ROAS worked like a guardrail: the system would happily beat your number if it could. Now, according to the Google Ads Help Center page "Changes to target-based bid strategies," the same campaign "now performs more consistently towards your bid target."
Google’s own example is blunt. In its words: "If your campaign’s target CPA is $10 but your recent actual CPA performance is $5, your campaign now delivers more closely to a $10 actual CPA. Update your target to $5 to maintain your recent performance."
The change applies to Search, Shopping, Performance Max, Demand Gen, Display, Hotel and Travel campaigns, per that Help Center page. App campaigns, video reach campaigns and video view campaigns keep the old behaviour. Google gave advertisers a Bid Target Adjustment tool on July 6, 2026, and the new bidding logic went live platform-wide on August 17, as PPC Land reported in August.
Search Engine Land revisited the change on September 9, 2026, with paid search consultant Reva Minkoff noting that Target CPA behaved this way around 2015 and 2016, when Google described it as bidding so the average cost per conversion would equal the chosen target. We are back to the original meaning.
Does this affect my small-business account?
It affects you only if a campaign shows the "Limited by budget" status and uses Target CPA or Target ROAS, and most small-business Search campaigns on a $500 to $3,000 monthly budget do exactly that.
Here is why. A budget-limited campaign has more demand than money. Before August 17, the algorithm spent that budget on the cheapest available conversions and beat your target. Now, if your target is loose, the system treats the gap as permission to bid higher, and it spends the same budget on fewer, pricier leads.
The owners most at risk set a Target CPA once, watched the campaign beat it every month, and never touched it again. That "safety margin" is now the number Google is aiming at.
| Scenario | Before August 17, 2026 | After August 17, 2026 |
|---|---|---|
| Target CPA $50, budget limited, campaign was delivering $28 leads | Google kept delivering around $28 and treated $50 as a limit | Google steers toward roughly $50 per lead unless you lower the target |
| Target CPA $50, campaign already delivering $48 to $52 | No practical difference | No practical difference |
| Target ROAS 400%, campaign delivering 650% | Extra return was kept as upside | Return drifts toward 400% as bids rise |
| Maximize conversions with no target set | Spends full budget for most conversions | Unchanged |
Will this raise my cost per lead?
Yes, if your target was set above what the campaign was actually delivering, and no, if you tighten the target to your real numbers.
The mechanism is simple. Google’s Ads Liaison Ginny Marvin described the change as making the target "more precisely control your ROI," in remarks quoted by Optmyzr in August 2026. Precision cuts both ways: the campaign lands nearer the target from above or below.
The upside Google is selling is predictability. Its Help Center frames the change as letting you "confidently scale your campaigns" by raising budget without the target sliding around. For a business that was quietly banking the overperformance, it is a cost increase you did not ask for.
Search Engine Land’s September 9 piece describes one transportation client where progressively lowering the target from $10 to $5 produced a 75% reduction in CPA over two weeks. That is one advertiser’s result, not a benchmark, but it shows the target is a dial worth turning.
How do I know the right target to set now?
Set the target at your actual 30-day cost per conversion, then tighten it in 10% to 20% steps while watching impression share and conversion volume.
Google’s tool offers three choices: keep the current target, adjust it to recent delivery, or set a custom number. For most owners, "adjust to recent delivery" is the right first move because it locks in what the campaign was already doing. Search Engine Land’s September 9 recommendations add the discipline: decide whether the campaign exists for volume or efficiency, lower the target gradually, wait a full conversion cycle before judging, and watch impression share and CPC alongside CPA. Optmyzr adds: leave it alone for three days after a change, then correct in weeks two to four using post-change data only.
Our own accounts show why the number matters at small budgets. The GTA brokerage we run for Matrix Realty is on roughly $1,000 a month in tightly geo-targeted Search, and its cost per lead moved from $53.95 to $46.22 between May and August 2026 (case study). A target left at $54 on that account would now invite Google to give back most of that improvement. The private mortgage broker we run on Search and Performance Max hit 1,113 leads at $7.69 each in August 2025 (case study); on a high-volume account like that, a loose target is expensive fast.
What to do this week
- Open Google Ads, filter campaigns by "Limited by budget," and note which ones use Target CPA or Target ROAS. Those are the only campaigns this change touches.
- For each one, compare the 30 days before August 17 with the days after. If cost per conversion rose while conversions fell, the loose target is the likely cause.
- Use the Bid Target Adjustment tool (Campaigns page settings menu, or the account notification) to set the target to recent actual performance, then tighten by 10% to 20% every conversion cycle.
- If you would rather not manage a target at all, switch to Maximize conversions or Maximize conversion value with no target and let the budget cap spending.
Frequently asked questions
Did Google change how Target CPA works in 2026?
Yes. Effective August 17, 2026, Google Ads campaigns that are limited by budget and use Target CPA or Target ROAS "perform more consistently towards your bid target," according to Google’s Help Center. Previously those campaigns could beat the target; now they aim at it. Google’s example: a $10 Target CPA that was delivering $5 will move toward $10 unless you lower the target to $5.
Which Google Ads campaign types are affected by the August 17 bidding change?
Google’s Help Center lists Search, Shopping, Performance Max, Demand Gen, Display, Hotel and Travel campaigns, but only those with the "Limited by budget" status. App campaigns, video reach campaigns and video view campaigns keep the previous bidding behaviour. The change also applies through Search Ads 360, Display & Video 360, Google Ads Editor and the Google Ads API, as PPC Land reported in August 2026.
Should I lower my Target CPA after the August 2026 change?
If your campaign was consistently beating its target, yes. Set the target to your recent actual cost per conversion first, which preserves what the campaign was already delivering, then lower it gradually in 10% to 20% steps while watching conversion volume and impression share, the approach recommended by Search Engine Land on September 9, 2026. Cutting the target in half overnight usually starves the campaign of auctions.
Is Maximize conversions safer than Target CPA now?
For a small account that just wants the most leads from a fixed budget, Maximize conversions with no target is simpler and is unaffected by this change. Target CPA still makes sense when you have a hard number the business cannot exceed, but it now requires active management. Google’s own Help Center lists switching to a maximization strategy as one of the options for advertisers who do not want to manage the target.
