What is the INP?
NPI measures how quickly (or slowly ) your website responds when someone interacts with it, whether it's a click, a tap, or even when they type something. Basically, it's a metric that tells you how fast your page is at reacting. It's probably happened to you before: you click on something, and you're left waiting as if you were making an appointment with the doctor. Well, that's what NPI measures.

Unlike the old metric, FID (First Input Delay), which only measured how long it took for the page to react to the user's first click, INP is more demanding and looks at all interactions. So there's no getting away from it: if your website takes forever to respond, you're going to have problems.
