Google offers PageSpeed Insights API to help SEO pros and developers by mixing real-world data with simulation data, providing load performance timing data related to web pages.

The difference between the Google PageSpeed Insights (PSI) and Lighthouse is that PSI involves both real-world and lab data, while Lighthouse performs a page loading simulation by modifying the connection and user-agent of the device.

Another point of difference is that PSI doesn’t supply any information related to web accessibility, SEO, or progressive web apps (PWAs), while Lighthouse provides all of the above.

Thus, when we use PageSpeed Insights API for the bulk URL loading performance test, we won’t have any data for accessibility.

However, PSI provides more information related to the page speed performance, such as “DOM Size,” “Deepest DOM Child Element,” “Total Task Count,” and “DOM Content Loaded” timing.

One more advantage of the PageSpeed Insights API is that it gives the “observed metrics” and “actual metrics” different names.
