Summary Interaction to Next Paint (INP) is a measure of how quickly a webpage responds to user interactions. Browser rendering plays a crucial role in INP, as it affects the speed with which the visual feedback from user interactions appears. Optimizing rendering paths can significantly enhance INP scores. This guide

Summary Interaction to Next Paint (INP) is a newer web performance metric that evaluates a page's overall responsiveness to user interactions by considering the latency of all interactions throughout the page load lifecycle. In contrast, First Input Delay (FID) measures only the delay between a user's

Summary To reduce First Input Delay (FID) on your website, you need to implement JavaScript optimization techniques such as reducing the main thread work, deferring non-critical JavaScript, utilizing web workers, and optimizing third-party scripts. Here’s a detailed guide to improve your site's FID. Reduce Main Thread Work

Summary Poor Interaction to Next Paint (INP) scores are typically caused by long task execution times, JavaScript inefficiencies, heavy page payloads, and unoptimized rendering processes. Diagnosing these issues involves using tools like Google Lighthouse, Chrome DevTools, and other web performance analysis tools. Below is a comprehensive guide on the common

Summary Web fonts and images significantly impact the Interaction to Next Paint (INP) metric. Optimizing these elements involves using efficient loading strategies, compressing files, and serving responsive images and fonts. Here’s a detailed guide on how to enhance INP by optimizing web fonts and images. Understanding INP and Its

Summary Throttling and debouncing are two techniques in JavaScript used to control how often a function is executed, especially during high-frequency events like resizing or scrolling. Properly implementing these techniques can help improve Interaction to Next Paint (INP), enhancing user experience by maintaining smoother and faster interactions. This guide provides

Summary First Input Delay (FID) is a crucial web performance metric that measures the time from when a user first interacts with a page to the time when the browser is actually able to begin processing event handlers. Effective tools for measuring FID include Lighthouse, Chrome User Experience Report (CrUX)

Summary Improving First Input Delay (FID) involves optimizing web application performance to ensure that user interactions are prioritized and processed swiftly. This comprehensive guide covers techniques like breaking up long tasks, optimizing JavaScript execution, leveraging web workers, and using modern browser APIs to enhance FID. Breaking Up Long Tasks Identify

Summary Asynchronous loading of non-critical JavaScript and CSS files can significantly improve First Input Delay (FID). By loading these assets asynchronously, the browser can prioritize rendering the main content and executing critical tasks, leading to a more responsive user experience. Here’s a deep dive into why this technique is

Summary Reducing the impact of third-party scripts on First Input Delay (FID) can be achieved by optimizing script handling, employing strategic loading techniques, and minimizing the usage of unnecessary third-party resources. This guide provides various strategies and examples to improve FID effectively. Optimize Script Handling Asynchronous and Deferred Loading One
