Diagnose Why Your INP Is High

Diagnose Why Your INP Is High

INP — Interaction to Next Paint — measures how quickly your page responds when someone taps or clicks. A high INP means visitors tap and wait, which feels broken. Think of it like a light switch with a delay before the bulb reacts.

Here's how to track down the cause:
—
1. Open Chrome, right-click, Inspect, go to the Performance tab.
—
2. Hit Record, then click a button or open a menu on your page.
—
3. Stop recording.
—
4. Look for long horizontal blocks in the 'Main' row — those are tasks hogging the browser.
—
5. Click the longest one; Chrome names the script causing the delay.

Usually it's heavy JavaScript running all at once when you click.

Try this: Record yourself clicking your menu button and find the longest task block.
