Google PageSpeed Insights is a free tool that analyzes webpage performance, offering optimization suggestions to improve speed and user experience.
PageSpeed Insights (PSI) by Google measures how well your webpage performs on both mobile and desktop devices. It provides a performance score based on real-world data (field data) and lab data, helping webmasters understand loading times and user experience issues.
The tool offers specific recommendations like reducing server response times, optimizing images, leveraging browser caching, and eliminating render-blocking resources. Implementing these can lead to faster page loads, improved user satisfaction, and potentially higher rankings, as speed is a known SEO factor.
PSI also integrates with Core Web Vitals, focusing on metrics like Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS) to measure visual stability, interactivity, and load performance.
Best Practices:
- Optimize images and videos for web
- Minimize CSS and JavaScript files
- Enable browser caching
- Use a content delivery network (CDN)
- Prioritize above-the-fold content
