About Pagespeed Insights Checker

PageSpeed Insights is a Free SEO Tool that analyzes your page's speed performance. It reports on the real-world performance of a page for mobile and desktop devices and provides suggestions on how that page may be improved.

According to Google, PageSpeed Insights evaluates how well a page follows common performance best practices and computes a score from 0-100 that estimates its performance headroom.
It evaluates if a page can improve its performance in two areas:

  1. Time to above-the-fold load: Elapsed time from the moment a user requests a new page to the moment the above-the-fold content is rendered by the browser.
  2. Time to full page load: Elapsed time from the moment a user requests a new page to the moment the page is fully rendered by the browser.

The score is then categorized as being Good, Medium, or Low. 
The calculation assumes that a developer wants to keep the same appearance and functionality of the page.

  • Good: The page applies most performance best practices and there is little headroom for further optimization. The page scores 80 or above.
  • Medium: The page is missing some common performance optimizations and there is medium headroom for optimization. The page scores between 60 and 79.
  • Low: The page is not optimized and there is fairly large headroom for optimization. The page scores between 0 and 59.

The optimization score estimates the performance headroom of a page. 
A page with slow speed might have high optimization score because it has a low ratio of render-blocking resources relative to the total resources used by the page. On the other hand, a fast page might have a low optimization score because it has a high number of render-blocking resources relative to its total resources.
