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

Since 2025, Google has made over 20 improvements to bidding strategies for Search and Shopping.
New features include journey-aware bidding (beta) that helps AI understand complex lead generation paths by learning from both biddable and non-biddable conversion goals.
Smart Bidding Exploration, now extended to Performance Max and Shopping campaigns (beta), lets advertisers set ROAS tolerance to capture unexpected queries, boosting unique converting users by 27% on average.
Campaign total budgets allow flexible spending over days/weeks, reducing manual budget adjustments by 66%.
Upcoming demand-led pacing uses AI to automatically follow consumer demand, spending more on peak days and less on slow days, while respecting monthly budgets and daily limits.
