How-To Fix INP issue: longer than 200ms

Search Console Interaction to Next Paint

Note: Interaction to Next Paint (INP) is a pending Core Web Vital metric that will replace First Input Delay (FID) in March 2024. INP assesses responsiveness using data from the Event Timing API.

INP observes the latency of all interactions a user has made with the page, and reports a single value which all (or nearly all) interactions were below. A low INP means the page was consistently able to respond quickly to all—or the vast majority—of user interactions.
