Google Web Master tools start to incorporate some of that data to so you can see like how often you're terrible. If the icons are too close together, they'll ding you because it's difficult to touch the icon you meant to right? Especially for people with mobility issues or things like that. So I guess to wrap it up is like, you definitely want to fast website, fast app, whatever, but make sure you're viewing it from the user perspective. What is fast really mean? No, if something is running quick, but another part is really slow, make sure, right, that the way the user feels it is actually what we want them to feel it, I guess.
