What are Google PageSpeed Insights?

Google PageSpeed Insights is a free tool by Lighthouse that tests a website’s speed and identifies issues causing slow loading pages. Several tests are simulated on mobile and desktop devices to collect both lab data and real-world user experiences.

The result is a summary score of page-speed performance and issues causing bottlenecks.

Why Should You Care?

Every year, Google invests heavily into research surrounding page speed metrics and how it affects consumers habits in the real world. Why? Because the speed of your website directly predicts whether consumers will stay on your page or leave.

Think with Google Source: Google/SOASTA Research, 2017.

In one study, Google found that as page load times increase from 1 second to 10 seconds, the likelihood of a consumer leaving your site goes up by 123%. Another study by Google found that the average mobile page takes more than 15.3 seconds to fully load.

Yet another study by Google/55/Deloitte concluded that 61% of surveyed consumers stopped buying from a company because a competitor provided a better experience.

Speeding up your website is crucial to keep your customers happy. It’ll also attract customers from your competitors who are providing slow experiences.

Below are a few statistics (courtesy of Think With Google) to illustrate the impact of page load times.

For every second delay in mobile page load, conversions can fall up to 20%

How do you Interpret Google PageSpeed Insight Scores?

First of all, it’s important to note that having a passing PageSpeed score boosts your rankings in Google Search Results faster than maybe any other method. A passing score means your website meets the minimum requirements for the six categories that Google tests. See our websites report below as an example:

Here is a brief overview, in layman’s terms, of what each category means:

  • First Contentful Paint (FCP) — measures the time from when the page first begins loading to when any part of the page’s content first displays. A passing FCP score is 1.8 seconds or less.
  • Speed Index (SI) — how quickly the content is ‘painted’ (displayed) to the user, measured visually. A passing SI score is 3.4 seconds or less.
  • Largest Contentful Paint (LCP) — marks the point in time when the page’s main content has loaded — one of the most important metrics to estimate user experience. A passing LCP score is 2.5 seconds or less.
  • Time to Interactive (TTI) — measures how long a page takes until it is fully interactive and able to be used. A passing TTI score is 3.8 seconds or less.
  • Total Blocking Time (TBT) — related to TTI, TBT measures how severely unusable a website is prior to it fully loading. If you’ve ever visited a website with spotty cell reception, you know how important this is. A passing TBT score is 300 milliseconds or less.
  • Cumulative Layout Shift (CLS) — measures how much the content on your page moves, or shifts, as the page loads. This can be extremely frustrating for users. A passing CLS score is 0.1 or less.
