Running an eCommerce website is a 24/7 job. Slow performance can hinder sales and success, so website designers always need to find a careful balance between beautiful layout and fast load times. We looked at the top 25 websites for shopping around the web and set up a series of Full Page Check monitors on each one.
We looked at the total “weight” of the website (how much data was detected on the homepage), how many elements were detected on the page, and how the website performed compared to those numbers. Check out the data for yourself below!
Which websites “weighed” the most?
| Website | Weight | Elements | Performance |

| Kohl’s | 4,060.10 KB | 295 | 4.32 seconds |
| Staples | 3,799.70 KB | 398 | 10.81 seconds |
| Gap | 3,955.40 KB | 324 | 7.30 seconds |
| Overstock | 3,673.70 KB | 181 | 3.92 seconds |
Which websites had to load the most number of individual elements?

The only website to rank in the top 5 for both heaviest weight as well as fastest performance is Amazon, with the homepage registering 5,150.80 KB but still maintaining an average load speed of 2.32 seconds. By contrast, Staples has the most number of elements at 398 but one of the slowest performance speeds at 10.81 seconds.
