What do these numbers mean?

The 4 main indicators of the test are performance, accessibility, best practises and SEO. These 4 key indicators are out of 100 – highest being the best.

Why should I care about these numbers?

These 4 key indicators are a measurement of user experience. User experience is extremely important as bad user experience leads to fewer visitors and fewer returning visitors to the website.


Performance Indicator

The performance indicator shows the websites speed, the higher the better. Google also uses website speed as one of their ranking factors for websites on the search results.

Why is this important?

  • Google will be releasing a new website speed update for users of their chrome browser. This will show users a warning indicating that the website they are about to visit loads slowly.

Accessibility Indicator

Common Issues With Website Performance

Most websites will have unique issues that need to be researched and fixed. There are however some common issues that appear on most websites.

Dreamhost produced an article on the top ten most common website speed issues. 

Three of the most common issues are image non-optimisation, render-blocking resources and non-optimised CSS:

  • Render blocking Resources – Files that need to be loaded before the page can display to the user.
  • Non-optimised CSS – Loading CSS styles that are not needed.
  • Non-optimised Images – Images too big or not compressed can cause issues.
