Google is sending out email announcing that effective January 31, 2027, all product images in Merchant Center under 500 x 500 pixels will be disapproved and will not serve. This includes images in the image_link attribute and potentially secondary image attributes as well.

The recommended image size is 1500 x 1500 pixels or larger for optimal performance in AI Mode and AI Overviews Ads, signaling Google’s commitment to improving the quality of visuals in its advertising system. This resolution was already recommended for products to be used within YouTube Shopping ads.
