![](https://www.wordpromise.com/wp-content/uploads/2020/06/google-pagespeed.jpg)Google is known for providing various performance optimization tools and there’s no doubt that **PageSpeed Insights by Google** is one of the globally used page speed measurement tools, and for all good reasons as it provides great insights to the website developers to further optimize website for better performance.

**Google’s PageSpeed Insights (PSI)** measures the performance of a webpage on **mobile and desktop devices**, and then provide various suggestions to improve that page. It provides many type of data after scanning for developers:

1. **Speed Score**: It tells you how good your webpage is optimized as per all Google’s indicators and what is the overall score of your webpage according to Google’s score metrics.
2. **Lab data**is collected in a controlled environment, that is with a set of predefined devices and network settings. It is effective for debugging performance issues, and its testing can be easily reproduced.
3. **Field data**(also called _Real User Monitoring_ or RUM) includes performance data coming from real page loads. It’s effective to capture true, real-world user experience, but the set of metrics is limited as well as its debugging potential.
4. **Opportunities** includes recommendations about performance metrics that could improve page loading time. Each recommendation includes an estimation of the load time the page could save if the suggestions were implemented.
5. **Passed Audits** This tells you how much your website is already optimized from performance prospective and doesn’t require further optimization or developer’s intervention.
