Interaction to Next Paint (INP): The New Performance Metric You Need to Know About

As user expectations for fast, seamless online experiences continue to rise, businesses must keep pace. A crucial part of this involves staying abreast of the metrics that matter most. In 2022, Google took a significant step in this direction by adding a new metric to its Core Web Vitals: Interaction to Next Paint (INP).

This addition, along with Time to First Byte (TTFB), marks a significant shift in how we evaluate and optimize websites for performance and user experience. INP measures the time from when a user interacts with a web page to when the browser renders the visual response to that interaction. It's an essential indicator of a website's responsiveness and a critical factor in user satisfaction.

The introduction of Interaction to Next Paint underscores Google's commitment to pushing the web towards better user experiences. It emphasizes the importance of not just how quickly a page loads, but also how swiftly it responds to user interactions. This shift in focus is set to redefine our understanding of website optimization, making INP a performance metric every business needs to know and master.

Here we’ll ask ‘what is Interaction to Next Paint (INP)?’ and look at how it can level up your performance online.

What is Interaction to Next Paint (INP)?

As we delve deeper into the complex world of web performance metrics, it's crucial to first grasp what INP represents. The measurement is in milliseconds, a scale that might seem minute, but holds significant implications for a website's overall responsiveness and user experience.

In simpler terms, INP gauges how swiftly your website can respond to user actions and provide them with immediate, visual feedback. Whether it's a click on a button, a swipe on a carousel, or a submission of a form, these interactions need to be met with quick responses to ensure smooth user experiences.

The scores for Interaction to Next Paint are categorized into three main brackets:

  • Under 200 milliseconds: This is the ideal score. It indicates that your page is highly responsive, reacting promptly to user interactions and thus, doesn't require any improvements.
  • Between 200 to 500 milliseconds: While this range is not alarmingly bad, it does signal that your page could use some optimization to improve its responsiveness.
  • Above 500 milliseconds: This score signifies poor responsiveness. A score in this range requires immediate attention as it strongly suggests that users are likely experiencing noticeable delays when interacting with your website.

As Google puts it, "Good responsiveness means that a page responds quickly to interactions made with it. When a page responds to an interaction, the result is visual feedback, which is presented by the browser in the next frame the browser presents."

Why Interaction to Next Paint Matters

The significance of INP lies in its direct impact on user experience. Quick visual feedback is not just about speed; it's about ensuring users that their actions are being acknowledged and processed.

According to Google, some interactions may naturally take longer than others. However, for complex interactions, it's vital to provide some initial visual feedback quickly to assure the user that their action has been registered.

Here are a few reasons why INP matters:

  • User Satisfaction: A responsive site that provides quick visual feedback enhances user satisfaction and engagement.
  • Conversion Rates: A positive user experience, marked by swift responses, can lead to higher conversion rates.
  • SEO Rankings: Google incorporates user experience metrics like INP into its ranking algorithm, meaning better INP scores can potentially improve SEO rankings.
  • Reduced Bounce Rates: If users see that their actions are resulting in immediate responses, they're less likely to abandon the site, leading to lower bounce rates.

INP is more than just a performance metric. It's a reflection of how your website communicates with its users, providing them with immediate, reassuring feedback and thereby enhancing overall user experience.

Interaction between Next Paint and Core Web Vitals

The significance of this modification to Core Web Vitals cannot be understated. It underscores the increasing importance of responsive design and quick visual feedback in today's digital landscape.

A well-optimized INP score can significantly influence your website's Core Web Vitals, leading to several potential benefits:

  • Improved Search Engine Rankings: Google considers Core Web Vitals as part of its ranking algorithm. Therefore, better INP scores can potentially lead to higher search engine rankings.
  • Increased Visibility: Higher rankings invariably lead to greater visibility, making your website easier for potential users to discover.
  • Enhanced User Experience: A good INP score indicates a responsive website, which can significantly improve the overall user experience.
  • Boosted Conversion Rates: An improved user experience can lead to increased engagement and higher conversion rates.

The integration of INP into Core Web Vitals represents a strategic shift in how we understand and optimize website performance. It emphasizes the importance of swift, visual feedback in response to user interactions, ultimately aiming to create more engaging, user-friendly online experiences.
