2021 Top 50 Websites Worldwide

To give context to the list, for brevity we have selected some of the top 50 most visited websites in the world based on monthly traffic. The websites are ordered by page weight.

For the purpose of quantifying potential data transfer savings, let's assume the weight of a webpage should be a very reasonable size of 1MB. We are not saying these websites are bad or doing anything wrong! We are merely showing a potential outcome if there were optimizations made.

KB = Kilobytes, MB = Megabytes, M = million, TB = Terabytes (each Terabyte = 1,024 GB)

We've only looked at a handful of websites and these are crude numbers but for illustrative purposes, if we extrapolate further to the millions of high traffic websites worldwide, you can easily recognize there is a massive potential for energy savings here if we just care a little.
