Product group structure is fundamental to Google Shopping success. Proper segmentation can improve ROI by 25-40% and make bid management significantly more effective. This comprehensive guide covers proven product group strategies.

Why Product Groups Matter

Product groups directly impact:

Understanding Product Groups

What Are Product Groups?

Product groups are how Google Shopping organizes your products for bidding:

• Each product group can have its own bid
• Products are automatically grouped by attributes
• You can create custom groupings

Default Product Group Structure

Google automatically creates groups by:

• All products - Default catch-all group
• Brand - Grouped by brand name
• Category - Grouped by product category
• Item ID - Individual products
• Condition - New, used, refurbished
• Custom labels - Your custom groupings
