Introducing INP for Core Web Vitals, FID to Go Away

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

INP for Core Web Vitals

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.

My dad taught me to dream big and to work my butt off to make those dreams a reality. Building stuff and helping people succeed is what we are about. And if things don't work the first time, we try again differently. Growing bigger is one thing; growing better is what we aim for.
