Google Introduces Smart Bidding Exploration in Performance Max

Google has rolled out a new feature—Smart Bidding Exploration—within Performance Max campaigns, designed to give advertisers more flexibility and potentially boost conversions. While this update opens the door to new opportunities, it also raises important questions about efficiency and return on ad spend (ROAS).

What Is Smart Bidding Exploration?

The new toggle in Performance Max campaigns allows Google’s system to relax ROAS targets when it sees fit. By loosening rigid bidding limits, advertisers may capture additional conversions, even if some come from lower-intent or higher-cost queries.

This feature was first announced at Google Marketing Live and tested within search campaigns before making its way to Performance Max.

Why It Matters

Marketers are often stuck between chasing growth and maintaining efficiency. With Smart Bidding Exploration, Google is taking more control—expanding reach but risking diluted ROAS.

According to Google, early tests showed:

• 18% increase in unique converting query categories
• 19% lift in total conversions

These numbers sound promising, but they highlight the balancing act between scaling campaigns and preserving profitability.

Smart Bidding Exploration gives advertisers a chance to uncover untapped demand, but it comes with tradeoffs. If you’re running Performance Max campaigns, testing this feature could reveal new opportunities. Just keep a close eye on efficiency metrics to ensure incremental conversions actually deliver meaningful returns.
