PageSpeed Insights is a tool provided by Google that helps website owners and developers analyze the performance of their webpages. It measures both desktop and mobile page speeds, providing detailed insights on how quickly a page loads and interacts with users. The tool evaluates your website’s performance using metrics like Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS), which are part of Google’s Core Web Vitals.
PageSpeed Insights provides two types of reports:
- Lab Data: Based on a simulated environment to show potential issues in a controlled setting.
- Field Data: Collected from real-world user experiences, offering insights into how your site performs under typical conditions.
The tool not only scores your page out of 100 but also provides specific recommendations for improvement. These can include suggestions like compressing images, reducing JavaScript execution time, or leveraging browser caching to boost loading speed.
By using PageSpeed Insights, you can make informed adjustments to enhance your site’s speed, user experience, and SEO performance, ultimately leading to better search engine rankings.
