Google is changing how it delivers budget-limited campaigns that run on Target CPA or Target ROAS. If you set a target a year ago and never touched it again, from 17 August you start paying that number — not the one you pay today.

**Monday, 17 August 2026.** We re-read both of Google's pages this morning and the wording has not moved: *“Starting August 17, 2026, Google will be making changes to its bidding systems”*. Note the tense — on the day itself, Google still describes the change as beginning rather than done, so nobody should expect a confirmation screen. The deadline that has actually expired is Google's own advice: it asks you to review budget-limited campaigns on target strategies *“by August 17, 2026”*. That is today, and it is the last day of the window Google gave you. The Bid Target Adjustment Tool is, in Google's words, “now live and available in Google Ads”.

This isn't a penalty and it isn't a price rise. It's a change of logic: the target used to be a ceiling the algorithm was free to beat, and now it's a destination it moves toward. Google reports, from its own testing, an 18% lift in unique converting query categories and a 19% lift in conversions (source: Google, cited by Search Engine Journal, July 2026). Translated: more conversions, at the price you declared.

## Who this actually hits

Three things have to be true at once:

- the campaign shows the status **"Limited by budget"**;
- it runs a target-based strategy — **Target CPA** or **Target ROAS**;
- it's a **Search, Shopping, Performance Max, Demand Gen or Travel** campaign. Hotel and Display campaigns already run on the new behaviour; App campaigns, Video reach campaigns and Video view campaigns keep the old one (source: [Google Ads Help](https://support.google.com/google-ads/answer/17061251), re-read 17 August 2026).

If you run Maximise conversions or Maximise conversion value *without* a target set, this doesn't touch you. And if your budget isn't being fully spent, likewise — Google's FAQ is explicit that campaigns which are not budget-constrained *“will not change their behavior”*.

Two more boundaries worth having in writing, because the announcement gets repeated loosely. Demand Gen campaigns on **Target CPC** are in scope as well — the [FAQ page](https://support.google.com/google-ads/answer/17125145) names that strategy specifically, and the Ads API release notes for v22 record Target CPC arriving for Demand Gen. And manual CPC and Target Impression Share are *not* in scope at all: if that is what your campaigns run on, you can close this article.

One operational detail that catches agencies rather than advertisers: if your campaigns are managed through Search Ads 360, the adjustment tool does not appear in Google Ads at all. You open Search Ads 360 and use the notification banner there, “Review bid strategies”.

One detail Google added to the page since we first wrote this: on multi-channel campaigns — Performance Max and Demand Gen — you may also see traffic redistribute across channels, because the system now optimises toward the target you entered rather than under it.

## Why an old target is the problem

This is the part that matters. A target isn't a technical setting, it's a price promise you made at some point in the past. And in most accounts that number was entered once, at launch, off an estimate — and nobody has looked at it since.

Take a European online store that set a €25 Target CPA back in 2024, when that seemed reasonable. Since then the campaign has settled and closes at €13. The margin was recalculated on 13. The monthly budget was signed off on 13. From 17 August, the campaign is entitled to climb back toward 25 — and it will, bringing more conversions with it. Volume goes up, cost per conversion nearly doubles. Nothing broke: Google simply started taking seriously the number you wrote and then forgot.

> A target you haven't reviewed in a year isn't a setting. It's a number you guessed once — and from 17 August, it's a number you pay.

## What we do on the accounts we run

The rule we apply on every new account we open predates this announcement, but it fits it almost too neatly: **we set no target for the first two weeks**.

On the Search campaign we launched on 25 July 2026 for an Italian client, we started on Maximise conversions with *no* Target CPA and ad rotation set to "rotate evenly", specifically so the account would collect real data first. The target (around €15) gets set afterwards, on what the account shows, not on what we estimated before a single conversion existed. The reasoning was always mundane, and this change makes it concrete: a target set before you have data is a guess, and from 17 August the guess becomes the invoice.

On the accounts we already run, the job was a single one: put every budget-limited campaign through the comparison between real CPA and written target, and bring the target down wherever the gap was wide. That's not optimisation. It's housekeeping — and it is the same half hour whether you do it before the change or in the week after, because the comparison does not expire.

## What to do, in order

If you manage the account yourself, this is about 30 minutes of work:

1. **Filter campaigns by "Limited by budget" status.** Those are the only ones that matter today.
2. **Check which of them use Target CPA or Target ROAS.** The column is "Bid strategy".
3. **Put reality next to the target.** Real CPA (or ROAS) over the last 30 days, against the number in the settings. That gap is your exposure.
4. **Lower the target where the campaign beats it comfortably.** If you want to keep today's CPA, the target has to look like today's CPA.
5. **Use the Bid Target Adjustment Tool** (live since 6 July 2026) if you have many campaigns to fix.
6. **Diary a check for the week of 18–24 August.** Seven days of data after the switch is the only thing that tells you whether the maths was right.

## Three quick questions

### Do I need to pause campaigns on 17 August?

No. Nothing stops and nothing resets. The only thing that changes is how close to your target the system delivers. If your target is correct, there's nothing to do.

### If I raise the budget, do I avoid this?

No — if anything the logic runs the other way. The change applies precisely to budget-limited campaigns, and Google states that delivery will be more consistent toward the target *including when budget adjustments are made*. More budget buys more volume at the declared target, not a lower CPA.

### What if I do nothing?

Campaigns delivering below target today will climb toward it. You'll get more conversions and a higher cost per conversion. For some businesses that's genuinely good news — if the margin carries it. The problem only appears when nobody checked whether it does.

A change with a fixed date is only as useful as the page that carries it, so we opened both Google pages in all three of our languages this morning and counted where the date actually appears. It appears four times on *Changes to target based bid strategies* and three times on the FAQ — and the counts are identical in English, Romanian and Italian. This one was translated properly, which is worth saying plainly, because the last two Google migrations we audited this month were not: one carried its announcement on four English pages and none of the Romanian or Italian ones.

The caveat comes from Google itself. Both localised versions carry the notice that the page *“might include AI-translated content”* and that AI translations may contain errors. That is not a hypothetical worry: on a different Google Ads help page this week we found the English conditional “may be subject to” rendered in Italian as a flat requirement. Where the money is in the sentence, read the English page too.

## Want us to look at the account?

We run [Google Ads](https://cittago.com/services/google-ads/) for businesses across Romania and Italy, and this is one of the few checks with a fixed date on the calendar. If you have budget-limited campaigns with a target and you're not sure where you stand, we'll go through it with you and tell you honestly whether anything needs changing. [Book a meeting](https://cittago.com/book/).

If the wider context helps, we've also written about [how Performance Max works in 2026](https://cittago.com/blog/google-ads-performance-max-2026/) and about [Meta Ads benchmarks for European e-commerce](https://cittago.com/blog/meta-ads-ecommerce-2026/).

Last updated: 17 August 2026, the day the change starts. Both Google pages — [Changes to target based bid strategies](https://support.google.com/google-ads/answer/17061251) and its [FAQ](https://support.google.com/google-ads/answer/17125145) — were re-read this morning in English, Romanian and Italian. They still say “Starting August 17, 2026” in the future tense, they still carry Google's recommendation to review budget-limited campaigns by that date, and they add two scope details we have now written into the article: Target CPC for Demand Gen is included, manual CPC and Target Impression Share are not. We update this page when Google marks the rollout complete.

## Questions and answers

**Do I need to pause my campaigns on 17 August 2026?**

No. Nothing stops and nothing resets. The only thing that changes is how close to your target the system delivers. If your target already looks like the CPA you actually pay, there is nothing to do.

**Does this change how the Google Ads auction works?**

No. Google's FAQ page is explicit: this is a bidding change and the auction mechanisms do not change. What changes is whether a budget-limited campaign is allowed to keep delivering under the target you wrote.

**Does it affect campaigns that are not limited by budget?**

No. Google states that Target CPA and Target ROAS campaigns which are not budget-constrained will not change their behaviour. Check the campaign status column first: if it does not say Limited by budget, this announcement is not about you.

**Which bid strategies are actually in scope?**

Target CPA and Target ROAS across most campaign types, plus Target CPC specifically on Demand Gen campaigns. Manual CPC and Target Impression Share are not affected at all, per the same Google FAQ page.

**Which campaign types keep the old bidding behaviour?**

App campaigns, Video reach campaigns and Video view campaigns continue on the previous behaviour. Hotel and Display campaigns already moved to the new one, so for them nothing happens on 17 August either.

**If I raise the budget, do I avoid the change?**

No, and if anything the logic runs the other way. The change applies precisely to budget-limited campaigns, and Google says delivery becomes more consistent toward the target including when budget adjustments are made. More budget buys more volume at the target you declared, not a lower cost per conversion.

**What happens if I do nothing at all?**

Campaigns that deliver below their target today will climb toward it. You get more conversions and a higher cost per conversion. For some businesses that is genuinely good news, if the margin carries it. The problem only appears when nobody has checked whether it does.

**Where is the Bid Target Adjustment Tool if I use Search Ads 360?**

It does not appear in your Google Ads account at all. You sign in to Search Ads 360 and use the notification banner there, labelled Review bid strategies. This catches agencies more often than advertisers.

**Will Google adjust my targets or budgets for me?**

No. Google's own page states that it will not automatically adjust your bidding targets or budgets. The number only changes if you change it; what changed on 17 August is what that number does.
