⚡ What is INP?
INP, or Interaction to Next Paint, is a performance metric that measures the time between a user interaction and the next display update. It is a crucial component of Google's Core Web Vitals which focuses on user experiences on the web.
⭐ Why is INP Important for Site Performance?
INP is vital for understanding how responsive a web page is to user inputs. Good INP scores indicate that a page quickly reacts to user interactions, enhancing the user experience and potentially boosting search engine rankings.
⚙️ How Does INP Work?
- A user interaction, such as a click or keystroke, occurs on the website.
- The browser processes this interaction and prepares the next visual update.
- The time taken from the interaction to the rendering of the updated display is recorded as the INP score.
- Optimizing code and server responses can reduce the INP, improving user experience.
📌 Examples of Factors Affecting INP
- Heavy JavaScript execution delaying the next paint.
- Server response times affecting resource loading.
- Inefficient DOM updates and rendering patterns.
✅ Best Practices to Improve INP
- Optimize JavaScript to execute efficiently and minimize blocking.
- Leverage browser caching to speed up resource loading.
- Ensure server response times are quick by optimizing backend processes.
- Use lazy loading and code splitting to manage resources better.
⚠️ Common Mistakes That Affect INP
- Ignoring optimization of third-party scripts.
- Overloading the main thread with synchronous JavaScript.
- Neglecting mobile responsiveness which can affect load times.
🛠️ Tools for Measuring INP
- Google Lighthouse – measures INP as part of its performance audits.
- WebPageTest – provides detailed insights on interaction latency.
- Chrome DevTools – aids in analyzing performance bottlenecks.
📊 Quick Facts About INP
- INP is a new metric considered crucial for enhancing user experience.
- Sites with good INP scores often see better user engagement.
- Optimizing for INP may also improve other performance metrics.
❓ Frequently Asked Questions About INP
Is INP the same as FID?
No. While both metrics focus on user interaction, INP measures the time to next paint, whereas FID measures the delay in processing input events.
How can I measure my site's INP?
You can use tools like Lighthouse or WebPageTest to obtain INP scores and understand where improvements can be made.
Does a low INP score help with SEO?
Yes, a lower INP score generally indicates better user experience, which can positively influence SEO rankings as part of the Core Web Vitals.
