LCP: how long until it shows
Measures when the main content appears. Google recommends 2.5 seconds or less.
INP: how long until it responds
Measures how fast the page reacts when you tap a button. The recommended value is 200 milliseconds or less.
CLS: nothing should jump
Measures how much content shifts while loading. The target is 0.1 or less; nothing is more frustrating than tapping the wrong button.
Why we hand over the numbers
We measure these before launch and give you the result in writing, so speed is a fact, not a promise.
