Have you ever wondered how websites work and why some pages load faster than others? Well, Google has developed something called Core Web Vitals, which are like the health checkup for websites. One of these vitals is called Interaction to Next Paint, which measures how quickly a web page becomes interactive after you click on it.
Now, Google thinks this is important for your online experience. Imagine you’re trying to read an article or buy something online. You don’t want to wait forever for the page to respond when you click a button, right? That’s where Interaction to Next Paint comes in – it’s all about making sure websites react quickly to your actions.
So, what can website owners do to ensure they score well on Interaction to Next Paint? Well, they need to optimize their websites to be faster and more responsive. This might mean using smaller images or cleaning up the code behind the scenes. By doing these things, websites can ensure that you, the user, have a smooth and enjoyable experience online.
Have you ever noticed how some websites just feel better to use? Google thinks about that too! They’re always working on making your experience online smoother. Recently, they made some changes in how they measure the goodness of a website when you visit it.
Google introduced something called Core Web Vitals a while back. These are like the gold standard for a great website experience. Imagine them as your website health checkup. But Google realized they needed to improve how they measure these vitals to understand how you, the user, feel when you’re on a website.
Now, they’ve come up with a new measure called Interaction to Next Paint (INP). This is a big deal because it helps Google understand how fast a website responds after you click on it. If a website is slow to respond, it can be frustrating, right?
So, what does this mean for website owners? Before INP becomes a big deal in how Google ranks websites, website owners need to make sure their sites are super responsive. They might need to make changes behind the scenes, like using smaller files for images or cleaning up the technical stuff. This guide will help website owners understand Google’s new metric and how they can make their websites faster and more enjoyable for you, the visitor!
What Is Interaction To Next Paint?
Interaction to Next Paint, often abbreviated as INP, is a term used by Google to measure how quickly a web page becomes interactive and responsive after a user interacts with it, such as clicking a button or a link. In simpler terms, it evaluates the time it takes for a website to react and show signs of activity after you’ve done something on the page.
Think of it this way: when you visit a website, you might want to click on a button to see more information or make a purchase. Interaction to Next Paint measures the delay between your click and the website’s response. A fast INP means the website feels snappy and responsive, while a slow INP indicates a laggy and less enjoyable user experience.
Google considers INP as an important factor because nobody likes waiting around for a website to react after taking an action. It’s a part of Google’s efforts to ensure that websites provide a smooth and speedy experience for users. So, when website owners optimize their sites to have a fast Interaction with Next Paint, it means you, as a visitor, can enjoy a more seamless and enjoyable browsing experience.
Why Google Switched from First Input Delay to Interaction to Next Paint: The Reason Behind the Change
The previous First Input Delay metric had limitations in recognizing user frustration accurately.
Interaction to Next Paint (INP) enhances this metric in two key ways:
- INP accounts for the entire duration from user interaction to the subsequent visual update on the page, offering a more comprehensive view compared to the partial perspective of the First Input Delay.
- INP takes into consideration all page interactions and typically highlights the one with the most significant delay, addressing a broader range of user experiences. In contrast, the First Input Delay only focuses on the initial interaction, missing out on subsequent interactions.
What is the Ideal Interaction to Next Paint for My Website?
To ensure a positive user experience and comply with Google’s Core Web Vitals standards, your Interaction to Next Paint (INP) should ideally be under 200 milliseconds.
Interestingly, most websites had little trouble meeting the First Input Delay threshold, with 93% of mobile sites delivering a satisfactory experience. However, when it comes to the Interaction to Next Paint metric, only 64% of sites currently meet the desired criteria.
To assess your website’s performance, you can utilize free tools such as PageSpeed Insights or DebugBear. DebugBear’s “Web Vitals” tab not only evaluates your current INP score but also provides a historical overview of how your score has evolved.
What Leads to Low Interaction to Next Paint (INP) Scores?
The sluggish Interaction to Next Paint (INP) scores are often a result of continuous CPU processing on the page, hindering the browser from displaying updated content promptly. Now, let’s delve into the specific areas you should examine for potential INP problems.
The complete INP value comprises three distinct components that contribute to the overall score:
- Input Delay: This reflects the time it takes for the website to respond after a user’s interaction, like clicking a button.
- Processing Time: This measures the duration the browser spends processing scripts and other operations before updating the page.
- Presentation Delay: This accounts for the time it takes to visually render the updated content on the user’s screen.
Identifying and addressing issues within these components is crucial for improving your website’s Interaction to Next Paint performance.
How to Improve Interaction to Next Paint Performance?
If you’re uncertain about which pages on your website require optimization, a helpful starting point is the Core Web Vitals report in Google Search Console. This report provides specific URLs that exhibit slow performance.
Once you’ve identified the pages in need of optimization, there are several methods to pinpoint sluggish interactions on your website:
- Using the INP Debugger:
- Explanation: The INP Debugger is a specialized tool or software designed to analyze and diagnose Interaction to Next Paint issues on web pages. It helps developers identify specific elements causing delays in user interactions.
