As of August 17, 2026, Google Ads has updated how budget-limited campaigns behave when they use goal-based bidding strategies such as target CPA, target ROAS or target CPC. The change aims for more consistent performance against the advertiser's stated goal, rather than prioritizing spending the full available budget.
The context: advertising has become predictive
This adjustment isn't an isolated case — it's part of a broader structural shift in 2026: ad targeting has become predictive and automated. Ad platforms have gone from acting as simple inventory marketplaces to behaving like behavior-prediction engines, increasingly deciding on their own who to show each ad to and how much to bid for it.
The new Terms of Service, another step in the same direction
On July 1, 2026, new Google Ads Terms of Service came into effect that contractually authorize Google to use its own AI systems to format, select or even generate goals, ads and destinations on the advertiser's behalf. Combined with the August bidding change, the direction is clear: less direct manual control, more automation running underneath.
Other notable 2026 updates
- A new display placement for Demand Gen campaigns.
- The option to select specific placements: Display, Shorts, Gmail, Discover, YouTube in-stream and in-feed.
- Google Maps integration within Demand Gen inventory.
What this means for an SME managing its own campaigns
With more automation running in the background, the margin for manual error shrinks — but so does fine control over specific decisions. The general industry recommendation is to review the goals set for each campaign (CPA, ROAS, CPC) to make sure they still reflect the reality of the business, rather than letting old settings run on autopilot while the algorithm behind them has changed how it behaves.
