Google will require advertisers to meet a minimum budget threshold to run Demand-Gen campaigns starting March 2, 2026, according to a MediaPost report.

The policy enforces a floor on how much buyers must commit before accessing the format, which spans YouTube, Gmail, Discover, and other Google-owned surfaces. The exact minimum dollar figure has not been disclosed in the published report.

What Demand-Gen does

• Reaches users across YouTube, Gmail, Discover, and visual partners
• Supports image, video, and carousel ad formats
• Targets upper-funnel objectives: awareness, consideration, site visits
• Uses audience signals to feed Google's automated bidding for downstream conversions

Demand-Gen launched in 2024 as the successor to Google's Discovery campaigns. It competes directly with Meta's Advantage+ and TikTok's Smart Performance Campaigns, both of which use machine learning to consolidate targeting and creative selection.

What is changing

• Google will enforce a minimum budget on Demand-Gen buys
• The rule takes effect March 2, 2026
• The dollar figure and enforcement mechanism are not yet public

Who it affects most

• Small advertisers running one-off or pilot campaigns
• Agencies managing many low-spend client accounts
• Direct-to-consumer brands with limited monthly media budgets
• Marketers using Demand-Gen primarily for creative testing

What to watch next

• Whether the minimum is daily, weekly, or campaign-lifetime
• Whether Google applies the floor globally or by region
• How the threshold compares to Performance Max's existing minimums
• Whether exempt categories or verticals get grandfathered in

Minimum spend rules are not new for Google Ads. Search, Display, and Performance Max campaigns all carry daily or campaign-level spend floors. A Demand-Gen threshold extends the pattern to a format that, until now, has been accessible to small-budget advertisers running one-off tests.

The move fits a broader pattern at Google Ads. The company has steadily raised the operational bar on its automated campaign types, requiring more creative assets, broader audience signals, and now a higher minimum commitment. For brands and agencies, the practical effect is that Google's machine-learning-driven products now demand larger inputs of capital and creative to perform.

For agencies, the change raises operational questions. Smaller advertisers and test budgets could find themselves locked out, while established brands with committed annual media plans are unlikely to feel the shift. The impact will fall hardest on mid-market advertisers who treat Demand-Gen as a sandbox for new creative angles before scaling spend elsewhere.

A budget floor would push the product further away from experimental use. Brands with steady monthly commitments to upper-funnel video will not notice. Marketers using Demand-Gen for low-budget creative tests will have to consolidate spend or shift to other formats such as standard Display or paid social.

The policy also has implications for Google's competitive positioning. By raising the entry barrier, Google may be steering small-budget advertisers toward Performance Max, which has its own minimum commitments but offers a broader inventory pool. Critics may read the move as Google further locking in larger spend commitments at a time when brands are questioning the ROI of automated ad products.

Google has not commented publicly on the new policy. The MediaPost report did not name sources or quote Google executives. Until Google publishes the figure, agencies should plan for a threshold that excludes low-budget test campaigns and start client conversations about consolidating Demand-Gen spend or moving test budgets to alternative formats.
