Google INP Metric

From March 12, 2024, Interaction to Next Paint (INP) will be one of the core web vitals’ metrics, replacing First Input Delay (FID). Thus, knowing more about INP and its optimization is important to track and monitor it.

In simple words, INP is a metric to measure the time a visitor waits after their interaction with a web element. For instance, if they click a button to visit link and website takes some time to provide visual change on the screen. That time take after user interaction is INP. Lower INP score implies a fast response time, which is good in terms of website performance.

The basic idea is to ensure more web pages are responsive and provide the desired user experience. Thus, website optimization is required to improve INP along with LCP (Largest Contentful Paint) and CLS (Cumulative Layout Shift).

Measuring and optimizing INP using tools!

INP measures essential user interactions such as mouse clicks, taps on the device touchscreen, and pressing on a keyboard. And an INP below or at 200 milliseconds is a good score. So, webpage responsiveness is measured to understand these given and other user interactions to know if the INP score is precisely correct or needs improvements.

However, depending only on tools to measure INP and fix problems is not completely reliable since the INP issues begin in the JavaScript and CSS that are used by plugins, features, themes, and functionalities. For instance, installing and using animation effects load extra JavaScript and CSS code that influences INP scores negatively. In this case, one solution is to minify JavaScript and CSS. However, there can be another solution as well and that is auditing the code and finding some way out to optimize INP without disturbing its core essence.


So, INP optimization tools can be used to identify the root cause of delay in interaction with the next paint.
