Google Is Creating A New Core Web Vitals Metric

Google is developing a new responsiveness metric that could be a replacement for First Input Delay.

In a recent article by HTTPArchive Almanac on CMS usage around the world, the authors noted that all platforms are doing great on their key Web Vitals metric, First Input Delay (FID) and that Google is working on a new metric to anticipate.

Replaces First Entry Delay (FID). HTTPArchive publishes many articles on the state of the Internet each year.

Chapter 16 covers the Content Management System (CMS). This document has been reviewed and reviewed by Wix’s Backend Team Manager, Web Performance Officer, and various Google employees, and others.

This article raises an intriguing question about how First Input Lag lost value and mentions how Google is developing a new metric.

First Input Delay

Core Web Vitals is a group of user experience metrics designed to take a snapshot of how well a web page is performing for users, and First Entry Latency (FID) is one such metric.

FID measures how quickly a browser can respond to user interactions with a website, such as how long it takes to respond when a user clicks a button on a website.

The hallmark of FID is that the FID scores of all major content management systems such as WordPress, Wix, Drupal, etc. are lightning-fast.

Everyone Wins An FID Trophy

This article first mentions that most CMSs have very good FID scores.

And platforms that scored less scored relatively high, falling 5 percentage points behind. What’s wrong with FID is that it’s essentially a rate that everyone gets trophies.

If almost every site performs exceptionally well and everyone gets trophies, then that means there’s little reason for the metric to exist because the goal of modifying some part of the user experience has been achieved. Then, this article explains how Google (the Chrome team) is currently creating new metrics to measure response rates and response latency.

Input Response Delay Versus Full Event Duration

This article links to a recent Google article published on the Web. dev under the title “Feedback Required: An Experimental Responsiveness Score”.

The important thing in this article is that Google is working on a new input latency metric.

Knowing this indicator can help you prepare for what lies ahead. The main thing to understand about this new metric is that it doesn’t just measure individual interactions.

Measurement of individual groups of interactions that are part of a user’s behavior.

The article cited in HTTPArchive cites a November 2021 article seeking feedback from publishers, but this new metric has been in development for some time.

Two Approaches To Interaction Latency Metric

Web. dev explains that the Chrome engineers are exploring two approaches for measuring the interaction latency:

  1. Maximum Event Duration
  2. Total Event Duration

Maximum Event Duration

Interactions consist of several events of varying duration. This measure is based on the longest duration of the group.

Total Event Duration

This is the sum of all the event durations.

FID Is Likely Going Away?

It’s possible that FID could remain as part of Core Web Vitals but what’s the point if every site scores 100% on it?

For this reason, there is reason to believe that FIDs will disappear sometime in the relatively near future.

The Chrome team is looking for feedback on different approaches to measuring interaction latency. Now is the time to have a voice.
