How does Google measure PageSpeed score?

Your score is on a scale of 0 to 100 and is the combined total of:

1. Time to “above-the-fold” load:Elapsed time from the moment a user requests a new page to the moment the content is visible in the browser.
2. Time to full page load:Elapsed time from the moment a user requests a new page to the moment the full page is visible in the browser.

So, in a nutshell, Google sees your page as more “user friendly” if your score is 85 or more.

Because Google measures each page separately and not your site as a whole, SpeedBoost Ninja allows you to measure and benchmark 3 key pages from your store, your homepage, plus a collection page and a product page of your choice. This way you can understand each page type in isolation as they will typically have very different amounts of content.
