The largest retailers and marketplaces are selling 50 million more products than they were at the beginning of the year. This growth is evident in the 14% gain in the Product Assortment Index (PAI) since January.
As usual, marketplaces saw a larger absolute gain in product listings, with 47 million new listings versus 3 million for 1st-party retail. 1st-party retail, however, has grown 27% since the beginning of the year, which eclipses the 13% growth seen in Marketplaces.
Growth was especially strong in “Clothing, Shoes & Jewelry”, Home Improvement, Decor, and Books & Magazines.
We also observed a continuation in the trend of high variability on the marketplaces. Millions of products are listed and delisted on a weekly basis. This variability just doesn’t exist on the 1st-party retail side. The jury is still out on which experience is better for consumers.
