TL;DR

Introducing INP for Core Web Vitals, FID to Go Away

Why is Google changing how it measures website responsiveness?

Google is upgrading its Core Web Vitals in March 2024 by replacing the First Input Delay metric with Interaction to Next Paint to provide a more accurate measure of true website responsiveness.

  • INP Transition: Interaction to Next Paint (INP) will officially replace First Input Delay (FID) as the new Core Web Vitals responsiveness standard in March 2024.
  • Search Console: Google Search Console will integrate INP reporting ahead of the switch to help developers evaluate and optimize their pages.
  • Page Experience: Optimizing for INP is critical, but strong Core Web Vitals alone do not guarantee high search rankings without a holistic user experience strategy.

In early 2020, Google's Chrome Team introduced the Core Web Vitals to provide quality signals for web pages. Today, the Google Chrome team announced an upcoming change in the metrics for the Core Web Vitals better to evaluate the quality of a web page's user experience. This article explores this change and its meaning for Google Search and site owners.

A better responsiveness metric

Introducing INP for Core Web Vitals, FID to Go Away

One of the Core Web Vitals metrics, First Input Delay (FID), measures responsiveness, but FID has known limitations. This led the Chrome team to explore and seek feedback on a (then) experimental metric that addresses these limitations more effectively. In 2022, they announced Interaction to Next Paint (INP) as that new metric and started working with the community to test its efficacy.

After another year of testing and gathering feedback from the community, the Chrome team decided to promote INP as the new Core Web Vitals metric for responsiveness, effective March 2024, replacing FID. The Chrome team's blog post explains this change and the reasoning behind the new metric in more detail.

The new metric, INP, will replace FID as part of the Core Web Vitals in March 2024. To help site owners and developers to take the necessary steps and evaluate their pages for the new metric, Search Console will include INP in the Core Web Vitals report later this year. When INP replaces FID in March 2024, the Search Console report will stop showing FID metrics and use INP as the new metric for responsiveness.

If you have been following our guidance to improve Core Web Vitals, you will have considered the responsiveness of your pages already. The improvements made for FID are a good foundation to improve INP and the responsiveness of your pages.

We highly recommend that site owners achieve good Core Web Vitals for success with Search and ensure a great user experience. However, great page experience involves more than Core Web Vitals. Good stats within the Core Web Vitals report in Search Console or third-party Core Web Vitals reports don't guarantee good rankings.

To learn more about how Core Web Vitals fits into a holistic approach to page experience, see our guidance on page experience in Google Search results.

You can find more information about the new metric in the Chrome team's blog post and guidance on optimizing your pages regarding INP in this guide on optimizing INP.

Frequently Asked Questions

What are Google Core Web Vitals?

Introduced in early 2020 by Google's Chrome Team, Core Web Vitals provide quality signals to help evaluate a web page's user experience.

What major change is happening to Core Web Vitals?

The Google Chrome team is updating the metrics used to measure responsiveness. Specifically:

  • First Input Delay (FID) is being phased out.
  • Interaction to Next Paint (INP) is being introduced as the new metric.
Why is Google replacing First Input Delay (FID)?

Although FID measures a page's responsiveness, it has known limitations. The Chrome team developed and tested a new metric to address these limitations more effectively.

What is Interaction to Next Paint (INP)?

Interaction to Next Paint (INP) is the new Core Web Vitals metric designed to measure a web page's responsiveness. It was first announced in 2022 and tested extensively with the community before being promoted to replace FID.

When will Interaction to Next Paint (INP) officially replace First Input Delay (FID)?

INP will officially become the new Core Web Vitals metric for responsiveness, completely replacing FID, in March 2024.

How will the transition to INP affect Google Search Console?

The transition in Google Search Console will happen in two phases:

  • INP will be included in the Core Web Vitals report later this year to help developers evaluate their pages.
  • In March 2024, Search Console will stop showing FID metrics entirely and exclusively use INP.
What should site owners do to prepare for the INP update?

Site owners should continue focusing on the responsiveness of their pages. Fortunately, the improvements already made for FID serve as a good foundation to improve INP.

Do good Core Web Vitals scores guarantee high search rankings?

No, they do not. While Core Web Vitals are highly recommended for search success, they are just one part of a holistic approach.

  • Great page experience involves more than just these metrics.
  • Good stats in Search Console or third-party reports do not guarantee top rankings in Google Search.
