Pimp that INP

What is INP?

Interaction to Next Paint (INP) is a new Google Core Web Vital metric that will replace First Input Delay (FID) in March 2024. It measures the responsiveness of a web page to a click or a touch.

Web pages should respond quickly to our interactions (when we click something with a mouse, or touch a screen), and give visual feedback.  It's very frustrating when something causes a webpage to become unresponsive. With this new metric, an unresponsive web page would have a high INP score. 

INP is not a measure of how long the page takes to load in, but a measure of how long it takes to get to the next page, or stage of a page, when you interact with that page. A low INP score means the time between an interaction on that page and the next frame being painted is as short as possible.

For example, you might use JavaScript to display come content when the user clicks a 'show more' button. If the browser is still busy running code from the rest of the page, the user has to wait until this has finished before their interaction can see a response.

What's a Good INP Score?

• An INP below or at 200 milliseconds means that your page has good responsiveness.
• An INP above 200 milliseconds and below or at 500 milliseconds means that your page's responsiveness needs improvement.
• An INP above 500 milliseconds means that your page has poor responsiveness.
