This is the title of an article on the web.dev blog I came across. It is written by Patrick Kettner. The fact that this article is published on web.dev angers/annoys me. Let me explain why. Speed and conversion are highly correlated. This is generally known. However, Patricks suggestion that the amount of images and conversion are correlated comes out of thin air. Yes, speed is important, but big images are not the main culprits.
