Google May Replace FID With INP (Interaction to Next Paint) For Core Web Vitals
https://www.seroundtable.comAt Google I/O last week, Google’s Annie Sullivan and Michal Mocny introduced a new metric named INP or Interaction to Next Paint. INP measures overall responsiveness to user interactions on the page and it may or may not replace FID, First Input Delay, as a Core Web Vitals metric.
To be clear, nothing has changed yet with Core Web Vitals and INP is very much in the experimental phase. But there is a chance that INP will be added to Core Web Vital and / or replace FID in Core Web Vitals.
