New AI-powered bidding and budgeting innovations in Search and Shopping

Google Ads is rolling out a suite of innovations in 2025 to address the shifting landscape of consumer behavior and help advertisers capture hidden opportunities with AI-driven bidding and flexible budgeting. Key updates include:

- **Smarter Bidding**: Over 20 improvements to Search and Shopping bid strategies since 2025. Journey-aware bidding (beta) enables Search Ads optimizing to Target CPA to learn from both biddable and non-biddable conversion goals, improving lead generation. Smart Bidding Exploration, initially launched for Search campaigns, allows advertisers to set a ROAS tolerance to capture less obvious queries, resulting in an average of 27% more unique converting users. This capability will soon extend to Performance Max and Shopping campaigns.

- **Flexible Budgeting**: Campaign total budgets, now available for Search, Shopping, and Performance Max, let advertisers set a budget for a specified duration (days to weeks), reducing manual budget adjustments by 66% on average. Upcoming demand-led pacing for Search and Shopping will use Google AI to automatically optimize spend in line with consumer demand, increasing spend on peak days and reducing on slower days, while respecting monthly and daily limits.

- **Actionable Takeaways**: Ad ops teams should test Smart Bidding Exploration to expand reach beyond traditional targeting, especially for Performance Max and Shopping when available. Implement campaign total budgets to reduce manual effort and combine with demand-led pacing to automatically capture demand spikes without overspending. Track full conversion paths (e.g., lead-to-sale) to leverage journey-aware bidding for better CPA outcomes.
