The leaders in U.S. e-commerce—those ranked in the newly released Internet Retailer 2017 Top 1000—collectively grew online sales 15.5% in 2016.

But breaking down the list by product categories shows that retailers selling certain types of products are faring much better online than others.

For instance, the 102 Top 1000 e-retailers that primarily sell goods for the home—including furniture, home decor and housewares—collectively grew their web sales 27.5% last year. That was by far the biggest growth rate of all 15 product categories Internet Retailer analyzes, and it likely reflects the strong U.S. home-buying market in 2016.

The Mass Merchant category was the second-fastest growing last year, though the bulk of that came from Amazon.com Inc. Without Amazon, the remaining 49 mass merchants ranked in the Top 1000 grew 11.3% last year, which lags the Top 1000 total growth.

The other categories that outgrew the U.S. e-commerce market as a whole include Health and Beauty (which grew 18.3% online last year), Specialty (with 18.2% growth) and Hardware and Home Improvement (16.2% growth).

On the other hand, Office Supplies retailers suffered the most, with a collective 2.0% decline online last year, while computer and electronics retailers grew just 4.0%.
