And users clearly appreciate it. I was going over some bolt types with a design guy at my workplace yesterday for a project and his first instinct is to pull up the McMaster-Carr site to see what was possible. I don't know if we even order from them, since we pass through purchasing folks, but the site is just brilliantly simple and elegant.
Someone did an analysis of that site on tiktok or YouTube. It's using some tricks to speed things up, like preloading the html for the next page on hover and then replacing the shell of the page on click. So pre-rendering and prefetching. Pretty simple to do and effective apparently.
