Diagnosing FID Issues
Google PageSpeed Insights
This free tool analyzes your website and provides valuable insights into FID performance. Look for the “First Input Delay” metric in the report, aiming for a score of less than 100 milliseconds for optimal user experience.
Chrome User Experience Report (CrUX)
Access public CrUX data to see the FID distribution for your website across different devices and connection speeds. This helps identify specific user segments experiencing slow responsiveness.
DevTools
Leverage the Performance tab in Chrome DevTools to identify render-blocking resources and long JavaScript execution times, contributing to high FID.
Fixing FID Issues
Solution 1: Reduce JavaScript
Analyze your website for unused JavaScript files and remove them. Utilize async or defer attributes to prioritize critical scripts and delay non-essential ones.
Solution 2: Optimize Third-Party Code
Minimize the impact of external scripts by lazy-loading them or using alternative solutions. Consider removing unnecessary third-party widgets and plugins.
Solution 3: Optimize Images
Ensure images are properly compressed and resized for different screen sizes. Utilize lazy loading and image formats like WebP for efficient rendering.
Solution 4: Critical Rendering Path
Optimize the critical rendering path to ensure essential content loads first. This includes prioritizing critical styles and fonts above the fold.
Solution 5: Minimize DOM Size
A complex DOM structure can affect FID. Consider minifying HTML, CSS, and JavaScript to reduce their code size.
