Interaction to Next Paint (INP) is a key metric that tells you how quickly your website reacts to interactions, such as clicks, taps, and keystrokes, and how soon something changes on the screen after such action from users.
When someone visits your website, they expect it to be smooth, fast, and interactive. That’s why having a good INP score is important.

Understanding Interaction to Next Paint
Interaction to Next Paint (INP) is a performance metric for website ranking and overall user experience. It measures how responsive and smooth your website’s visual response to user actions is.
These interactions can be a click, keystroke, tap, or simply scrolling through your pages. INP ensures your website is just as welcoming and responsive for all visitors.
How Does INP Work?
If you want to have a better understanding of how INP works, here’s a simple breakdown:
User Interaction
First, a visitor interacts with your website by clicking, tapping, or pressing any key.
Response Time
The browser then processes the action from the user and prepares to display the result of their actions.
Next Paint
The screen then updates to reflect the user’s interaction. This can be anything you notice visually, such as a button lighting up, a dropdown menu appearing, or a page scrolling.
Remember, INP measures the time between a user’s interaction with your website and the resulting visual changes on the page. The shorter the time, the smoother their experience.
What’s a Good INP Score?
It doesn’t matter what kind of website you’re running, your INP score should be in top shape. Here’s how Google determines a good INP score:
- Under 200 milliseconds (Good): Your website is fast and user-friendly.
- 200 to 500 milliseconds (Needs improvement): You have to change some aspects of your website.
- Over 500 milliseconds (Poor): Your website is too slow and needs significant improvements.
Why Website Owners Should Care About INP
If you’re running a website to sell products or promote your business, your site’s INP matters greatly. Here’s why:
Improves User Experience
The faster your website, the more the users are engaged.
Boosts SEO
Google considers INP a Core Web Vital when ranking websites. A lower time can mean a higher chance of ranking on the first page of the search results.
Drives Conversions
Fast websites turn visitors into buyers. The quicker and smoother your website, the more revenue your business will generate.
Common Issues That Affect INP
If your INP score is poor, this means your website is slow, and it’s likely because of these reasons:
- Heavy images and videos: Large elements can slow rendering and make your website load slower.
- Large JavaScript files: These can clog your website’s pipelines, delaying the response.
- Inefficient code: Poorly written code can delay the loading of website content and other elements.
- Third-party tools: Extra widgets or ads can also slow down your website by blocking interaction processing.
How to Measure Your INP
Measuring your website’s INP is a lot easier if you have the right tools, such as:
- PageSpeed Insights: By entering your website URL, you can immediately get your INP score and suggestions for improving it.
- Web Vitals Chrome Extension: This tool can help you get real-time metrics while browsing your website.
- Google Lighthouse: It can help you run an audit on your webpage to see detailed INP results.
Improving Interaction to Next Paint
Improving your website’s INP score is all about cleaning everything for smoother and better user interaction. Here are some ways to improve it:
Optimize JavaScript
Heavy JavaScripts can block your browser from responding quickly, so it’s better to break them into smaller chunks and prioritize the critical scripts first.
Minimize Third-Party Scripts
Limit the number of social media widgets, ads, or tracking tools on your website. Each can increase load times, significantly affecting your INP.
Use Lazy Loading
Lazy loading should be prioritized. It makes images and other content appear only when users reach that part, ultimately speeding up interaction.
Optimize Images and Fonts
Compress images and content and use modern formats like WebP. Use only what’s necessary for your fonts and preload them for faster and smoother loading.
Test Your Website Regularly
Regularly testing your website’s performance can help you maintain fast and smooth interactions with visitors and address issues earlier.
Interaction to Next Paint and SEO
A simple click determines your visitor’s overall journey on your website. INP ensures that their first interactions keep them on track and help them quickly find what they want.
Website owners must understand INP. Remember, your website is your digital nametag. If it’s not responsive, it’s not trustworthy. Optimizing INP builds trust and keeps users coming back.
Conclusion
Interaction to Next Paint (INP) is not just a technical metric; it’s more of a reflection of how welcoming your website is to visitors, potentially turning them into future buyers.
