Google Just Made Your WooCommerce Feed the Ad Copy

Google’s AI Max for Shopping launched April 30, 2026, adding three changes to standard Shopping campaigns: text customization (auto-generated ad copy from Merchant Center feed attributes), Final URL Expansion (clicks routed to product pages you did not bid against), and Optimal Format Selection (Google chooses between Shopping and text formats). Independent analysis of 250 AI Max for Search campaigns found median +13% revenue but +16% higher CPA. WooCommerce stores running thin auto-generated feeds are now training Smart Bidding on AI-rewritten headlines they never approved.
