Google says the budget-limited bidding change is not a broader update.
Ahead of the 17 August change for budget-limited campaigns, Google's Ads Liaison, Ginny Marvin, confirmed that the update only affects budget-constrained campaigns using a target and is not a broader Smart Bidding change. She added that it will not result in any changes to spending, and that a campaign whose target is reset to its current achieved average should continue to perform as it does now.

What changed
The clarification followed a widely shared critique from Joey Bidner and a question from Maggie Humphrey about whether "more predictable performance" implied a broader shift in bidding, and continues the bidding target optimisation change covered in Week 25.
Why it matters for advertisers
For you, this means bidding plans can stay anchored to the announced scope, so avoid restructuring accounts on speculation. Yes this only impacts budget-constrained campaigns using a target because this is already the bidding behavior when campaigns using a target aren’t budget constrained. This change ensures expected bidding behavior will be the same regardless of whether a campaign using a target is budget-constrained or not. And that if advertisers do opt to change budgets on budget-constrained campaigns, they should expect more stable performance behavior as the campaign scales. Performance has often fluctuated unexpectedly, especially in budget-limited campaigns, as the budget is changed. This has been a frustrating experience for advertisers, making it difficult to scale campaigns with confidence. That’s what this change aims to address. In short we're making the controls clearer; the target will more precisely control your ROI.
