Save the date: this is when INP becomes a Core Web Vital, Google says

Back in June 2021, Google publicly started exploring ways to give site owners a better idea of how their website was reacting on user interaction. For example during navigation clicks, add-to-cart buttons and other interactive elements.

Google illustrated the timeline and lifecycle phases of INP in the following way:

  • May 2022 - Experimental
  • Chrome announced experimental support for INP
  • May 2023 - Pending
    Chrome is announcing that INP will become a Core Web Vital metric
  • March 2024 - Stable
    INP becomes a stable Core Web Vital metric, replacing FID

And today, Google announced the exact date of FID being replaced by INP: March 12, 2024.

This means that the Core Web Vitals now consist of:

Now that we have the date, we can do some calculations. Core Web Vitals for your website, and possibly individual webpages, are based on a 28-day rolling period. Therefore, you'll want your website to pass the INP assessment starting from February 13, 2024.

What you should do now

While the INP metric is relatively new, its impact on real user experience has existed all along. Google has made it accessible to site owners through public tools (PageSpeed Insights), Google Search Console, APIs, and JavaScript libraries.

CrUX and Goole Search Console

On a higher level, you can start examining historical CrUX data of your site to determine its trend over the past month.

After that, analyze your INP data in Google Search Console to identify the approximate number of impacted URLs on both mobile and desktop. This will help you pinpoint which pages are being affected the most.

Start collecting detailed info

Once you've identified the pages most affected, you'll have a starting point for improving your INP scores quickly.

But most tools stop at showing INP scores per URL, or maybe even template. To gain a more comprehensive understanding, you have two options:

  • Set up Google Analytics 4 (GA4) to measure site speed, but be prepared to add additional tracking for deeper insights.
  • Implement a dedicated RUM (Real User Monitoring) solution that collects detailed information automatically.

Now that we know that INP's deadline is March 12 2024, we changed tooltip information of INP and FID labels across our monitoring interfaces.

More importantly, here's how RUMvision is currently assisting site owners and stakeholders looking to improve INP on their sites or clients' sites.
