Google Ads is implementing significant changes to its Smart Bidding strategies and budget management for advertisers globally throughout 2026, shifting how campaigns target conversions and adhere to spending limits.

The updates include relabeling existing Smart Bidding options, adjusting how budget-limited campaigns perform, and introducing new tools for target adjustments, according to Google and industry reports.

Starting in June 2026, Google will separate Target CPA (cost-per-acquisition) and Target ROAS (return on ad spend) as distinct bidding strategies. These options, previously integrated within Maximize Conversions and Maximize Conversion Value, will now stand alone, though their underlying functionality will remain unchanged, Google reported.

A more substantial change will take effect on Aug. 17, 2026, when Google alters how budget-limited campaigns achieve their targets. The new system aims for closer adherence to set targets, moving away from a previous tendency for campaigns to potentially overperform their budget limits, according to Search Engine Journal.

To assist advertisers with this transition, Google launched the Bid Target Adjustment Tool on July 6, 2026. This tool allows advertisers to review and reset targets for campaigns that have been overperforming before the Aug. 17 policy change.

Smart Bidding, which utilizes artificial intelligence to bid at auction time based on millions of real-time signals, has evolved considerably from earlier manual bidding controls. The strategies available include Maximize Conversions, Target CPA, Maximize Conversion Value, and Target ROAS, each designed for specific business objectives.

Ginny Marvin, a Google spokesperson, previously said Smart Bidding does not require extensive historical conversion data, noting that new Search campaigns can be launched directly using target strategies.

For precise optimization, Google recommends using Smart Bidding Exploration. Advertisers who have utilized this feature have observed approximately 10 percent more conversions compared to those who simply lowered their ROAS targets, according to internal Google data.

These strategic adjustments underscore Google’s ongoing efforts to refine its automated bidding systems, providing advertisers with more granular control and predictable performance within their campaign budgets.
