Let’s start with a tool from Google itself. PageSpeed Insights ranks your website on a scale from 1 to 100 points by testing your website performance for speed and usability. Points greater than 85 means a well-performed website.

The tool uses Blink renderer to fetch a site and emulates the process for both mobile and desktop devices. Blink renderer is the same rendering engine Google is using in its Chrome browser.

Once a test will be completed, it will show you a list of both Possible Optimizations and Optimizations Found. Entries under Possible Optimizations list need to be fixed. Click Show how to fix to see possible solutions.

Below is a list of speed and usability rules analyzed by Pagespeed Insights:

PageSpeed Rules

  • Removed Render-blocking JavaScript
  • Use asynchronous scripts
  • Minify script resources
  • Enable compression
  • Leverage browser caching
