Google is rolling out a series of Smart Bidding and budgeting updates designed to help advertisers uncover new demand, capitalize on seasonal opportunities and maintain more predictable campaign performance.
What’s new. The updates include an expansion of Smart Bidding Exploration, a new Promotion Mode beta and changes to bidding target optimization for budget-constrained campaigns.
Driving discovery. Smart Bidding Exploration now allows advertisers to set a return on ad spend (ROAS) tolerance that enables campaigns to pursue additional conversion opportunities from search queries they may not currently be capturing.
Google says campaigns using the feature see, on average, an 18% increase in unique converting search query categories and a 19% increase in conversions.
The company is expanding the capability to Performance Max campaigns without product feeds and opening a beta for Shopping ads across both Performance Max and Standard Shopping campaigns.
Peak period bidding. Promotion Mode allows advertisers to temporarily adjust ROAS targets and allocate additional daily budget during high-demand periods such as seasonal events, product launches and flash sales.
What else is changing. Beginning Aug. 17, Google will update bidding target optimization for campaigns limited by budget, with the goal of delivering more consistent performance that better aligns with advertisers’ CPA and ROAS targets.
Starting July 6, advertisers will begin receiving notifications in Google Ads if campaign adjustments may be needed.
Why we care. These updates give Google’s AI bidding systems more freedom to find incremental conversions beyond existing keyword and audience patterns, potentially unlocking new demand that campaigns might otherwise miss.
The new Promotion Mode is particularly relevant for retailers and seasonal advertisers, as it allows temporary adjustments to ROAS targets and budgets during peak demand periods without requiring major campaign restructuring. Meanwhile, the bidding optimization changes aim to make performance more predictable for campaigns that are constrained by budget.
The bottom line. Google’s latest bidding updates are designed to help advertisers find new conversion opportunities, respond more aggressively during peak demand periods and maintain steadier performance as campaigns scale.
