What is Google Pagespeed Insights?

Google Pagespeed Insights is commonly referred to as PSI. PSI gives you both lab data and field data. Based on that, scores are determined. These are indicated in three categories: good, improvement needed and moderate. This gives you a clear understanding of where you can improve when it comes to speed.(1)

Multiple types of data

Both data are relevant to the performance of your website. Also, both types of data have advantages and disadvantages. The lab data are used to determine your performance score. This is good when this is above 90. Below 50 is moderate. So in between there is room for improvement. Field data are used to determine user experience.

For this purpose, FCP, FID, LCP and CLS are considered. The categories for field data are also given another color: green, orange or red. These colors visually represent which aspects are strong and weaker for the user experience.(2)
