What is INP in Google Search Console?

Interaction to Next Paint (INP) is a critical metric that measures the responsiveness and interactivity of websites. It evaluates the time it takes for a user's input, such as clicking a button or tapping a link, to trigger a visual response on the screen.

In March 2024, Google plans to replace First Input Delay with INP as one of the core web vital metrics, emphasizing its significance in website performance evaluation.

Google is going ahead with this update as they admit the constraints of FID in fully capturing the user experience. FID only accounts for the initial interaction and measures solely the first input delay; INP delivers a broader understanding by monitoring every page interaction from start to finish.

A fast INP ensures a smooth and seamless browsing experience. It allows users to navigate the site effortlessly, interact with various elements, and accomplish their intended actions without delays.

Website owners should take note of Interaction to Next Paint in their performance monitoring efforts, especially during the transition from FID to INP. Monitoring INP allows you to identify potential areas of improvement in terms of interactivity and responsiveness.

How is Interaction to Next Paint Measured?

The INP measurement starts when a user interacts with the website by clicking a button or entering text and ends when the browser renders the next frame. Hence, it includes the time taken for input, processing, and presentation delays. But how is this measured exactly?

Measuring the INP involves timing each component separately, then adding them together.

1. The input delay can be measured using the Event Timing API, which gives the delay between when an event was created and when it could start being processed.

2. The processing time can be measured using the User Timing API or a performance monitor that can track the time spent running JavaScript event handlers.

3. The presentation delay, or render time, can be measured using the Paint Timing API or a performance monitor. It measures the browser's time to repaint the screen following user interaction.

What Factors Impact Your INP Score?

Several factors can influence INP measurements. The complexity of the event handlers and the amount of JavaScript running on the page can impact processing time. The processing time will increase with many background tasks or complex calculations.

Factors like network latency and device hardware can increase input and presentation delays. For instance, heavily relying on JavaScript could considerably slow down a website’s performance on less powerful devices or older browsers, leading to a higher INP. Similarly, a slow network connection can cause a longer input delay as server responses take longer to arrive.

INP measurements can vary between browsers and devices is essential. Each browser has different ways of handling events and rendering pages. For example, some browsers may be better optimized for JavaScript processing, leading to lower processing times. On the other hand, different devices may have varying hardware capabilities, influencing the time it takes to render a page.

INP & Other Metrics

Several key metrics and indicators are associated with INP.

1. Input Processing Time (IPT): IPT measures the duration between a user initiating interaction and the browser processing that input. A shorter IPT signifies a more responsive website, indicating that the underlying technology quickly recognizes and processes user actions.

2. Time to Interactive (TTI): It quantifies the time required for a webpage to become fully interactive and ready for users to engage with its features and content.

When evaluating Interaction to Next Paint, a good score is typically characterized by low values for IPT and TTI. However, it is important to note that specific benchmarks for a good score may vary based on website complexity, user expectations, and industry standards.

How to Identify Interaction to Next Paint Using GSC?

To effectively identify Interaction to Next Paint using GSC, it is crucial to have a GSC account set up for your website. If you have not done so already, you can follow our comprehensive GSC guide to learn more about GSC and how to add your website to the platform.

Let us explore accessing and analyzing the INP data report using Google Search Console.

How to Access & Analyze the INP Data

As mentioned, Google will replace First Input Delay (FID) with INP as a new CWV metric starting in March 2024. As a proactive measure, Google has begun providing the INP data report in GSC, allowing website owners to optimize their sites for INP before it becomes a crucial factor in page performance.

Here are the steps to access your INP report in Google Search Console:

1. Sign in to your Google Search Console account.

2. Select your website property from the GSC dashboard.

3. Click on the Core Web Vitals section in the left-hand menu.

4. You will see the report for both mobile & desktop. Click on Open Report to access the report.

Once you have accessed the INP report, you will find a table displaying valuable information. This table includes details such as the severity of the issue, the type of issue, whether validation has been initiated, and the number of affected URLs.

Examining INP Data in GSC Core Web Vitals Report

When examining the INP data in GSC, you can identify specific pages or URLs with poor INP scores. GSC provides a group of URLs associated with each issue, enabling you to click on them and gain insights into the affected URLs.

If you discover INP issues within the report, it is recommended to start optimizing your website to improve INP before March 2024, when it becomes a vital CWV metric.

However, if no INP issues are detected, Google will indicate that "No INP Issue Detected," giving you confidence in your website's performance for the upcoming update.

Why is Your INP Value Not Reported in GSC?

In specific scenarios, GSC may not report any Interaction to Next Paint (INP) value. It can occur due to various reasons:

1. User Inactivity: When a page is loaded, but the user does not click, tap, or press any key on their keyboard, no INP value will be recorded. For example, if a user lands on a page and immediately leaves without interacting with any elements, no INP value will be reported.

2. Gesture-based Interactions: Interactions, such as scrolling, hovering over elements, or using gestures on touch devices (e.g., swiping), are not considered for calculating the INP value.

3. Bot Access: If the page is accessed by a bot, such as a search crawler, it may not trigger the necessary user interactions required for calculating INP.

What is the Notification that Google is Sending for INP Metric?

Recently, Google has sent email notifications to website owners about detecting Core Web Vitals INP issues on their sites. The email from Google highlights the transition to a new metric called Interaction to Next Paint (INP), which will replace First Input Delay (FID) as a Core Web Vital in March 2024.

The email states that Google Search Console has identified INP issues in the properties associated with the website. It encourages site owners to click on the listed properties to open the INP report for each property. However, the number of properties listed may be limited to a maximum of 10.

Here is a screenshot of the site's INP report from Google Search Console:

What Should be Done if You Receive this Notification?

If you receive a notification from Google that Search Console has detected INP issues in your site, the first thing to do is not panic. It is because these issues are not the sole determinants of your Google search rankings. Relevance remains the most significant factor that Google considers.

Here's what you need to do if you have received this notification:

1. Analyze The Report: First, click on the property to open the INP report. Understand what exactly the issue is and where it lies.

2. Consult Your Dev Team: Next, contact your developer team. Share the report with them and discuss the necessary technical changes that need to be made to fix the issue.

3. Prioritize Changes: As mentioned earlier, you have months to improve your INP score. Tackle the changes one at a time, prioritizing those that can be fixed quickly.

4. Monitor Progress: After the changes have been made, keep an eye on your INP score to see if there has been any improvement. If not, you might need to delve deeper into the issue.

5. Keep Providing Valuable Content: Regardless of your INP or other core web vital scores, continue to provide useful and meaningful content to your users. It is the ultimate key to a higher ranking on Google search.

It is important to remember INP is only one aspect of the page experience. Google uses other signals as part of its core ranking system to determine what makes a good page experience.
