Unpacking Google's New Core Web Vital: Interaction to Next Paint (INP)

Google is at it again, adding another metric to its Core Web Vitals - the Interaction to Next Paint (INP).This key metric further underlines the paramount importance of a seamless user experience. So, what does this change entail? Let's unpack it together.

What is INP?

Interaction to Next Paint, or INP, is a new performance metric that assesses a page's responsiveness to user interactions. It looks at the latency of all interactions that occur during auser's visit to a page. The final INP value is the most extended interaction observed, occasionally excluding outliers. To aim for a good user experience,an INP of 200 milliseconds or less is recommended.

What is it replacing, and when?

INP is set to replace the First Input Delay (FID) metric in March 2024. FID has been a valuable measurement of a page's interactivity, but INP promises to provide a more comprehensive evaluation of a page's overall responsiveness.

The Importance of INP

The introduction of INP signifies a shift in Google's emphasis from initial page load metrics to ongoing user interactions. It highlights the need for web pages to offer consistent, responsive experiences throughout a user's visit. By including INPin Core Web Vitals, Google underscores the necessity for developers to focus on optimizing every phase of user interaction.

How to Optimize for INP

Optimizing for INP involves Identifying and reducing input delays, optimizing event callbacks, and correctly structuring code for prompt rendering. These efforts aim to minimize the latency of interactions and ensure a smooth, seamless user experience.However, due to the complexity and depth of this topic, a more thorough guide is recommended for those who wish to optimize for this new metric fully.

Do Core web vitals impact search rankings?

Yes, as of Google's June 2021 update, Core Web Vitals are part of Google's page experience signals and do impact search rankings.

Core Web Vitals consist of three metrics: Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS), and now the newly announced Interaction to NextPaint (INP). These metrics measure loading performance, interactivity, visual stability, and overall responsiveness, respectively, of a web page. They provide a quantifiable measure of user experience. Google has stated that all else being equal, pages with good Core Web Vitals are more likely to rank higher in search results than pages with poor Core Web Vitals. However, it's important to note that while these metrics are significant, they are just one of many factors Google uses to determine page ranking.

So now what?

Start optimizing for INP! The introduction of INP to Google's Core Web Vitals is a significant development,highlighting the importance of smooth user interactions. As the digital landscape continues to evolve, staying updated with these changes and optimizing accordingly is crucial to providing a superior web experience and ensuring the growth of your online presence.
