Google is creating a new Vital Web Core

Google Core Web Vitals

Google may be developing a new metric for its Core Web Vitals which would replace First Input Delay, as the company has found that the vast majority of websites score very high on this metric, so it may have lost much of its value to Google.

Most websites have perfect scores on First Input Delay so this metric no longer makes sense for Google which will replace it next year.

Core Web Vitals are a group of user experience metrics designed to provide a snapshot of the performance of web pages and websites for users. First Input Delay is one of these metrics and is responsible for measuring the speed at which browser responds to the first user interactionThe time it takes for a response to occur when a user clicks on any element of a website.

The problem with the First Input Delay is that all the big content management systems like WordPress, Wix or Drupal get ultra-fast scores, both on desktop and mobile browsers, as they are optimized for it. Even websites created manually or built on less developed CMSs score relatively high.

For Google, if all websites score well on this metric, it means that there is no reason for this metric to exist, since it the goal of correcting this part of the user experience.

It is for this reason that Google is working on developing a new metric that measures input delay or “input delay metric“. This new metric would not only measure individual interactions, but groups of individual interactions that are part of a user’s action.

This would take into consideration the responsiveness of all user inputs, not just the first one. The full duration of each event would also be captured and those that occur as part of the same logical user interaction would be grouped together, defining the latency of that interaction as the maximum duration of all events.

Based on all of this, an aggregate score would be created for all interactions occurring on a page, over its entire lifecycle.

The goal is to create a metric that better captures the end-to-end latency of individual events and provide a clearer picture of the overall responsiveness of a page.
