What does the website grader do?
The website grader analyses your site for these four key user experience elements, gives you a total grade out of 100, and provides tips on how to improve them.

Performance
If you want to provide a good user experience, your site must be fast and responsive. The grader looks at factors like your page size and speed to measure you on this important metric.

SEO
It must be easy to find your website through search engines if you want to grow your business. The website grader checks how search-optimised your site is and suggests improvements.

Mobile
It's likely around 30-40% of your website visitors come from mobile, and good mobile performance is essential for a high ranking in Google. So it's vital that your site is just as usable on mobile as it is on desktop.

Security
Both users and search engines love secure websites that are SSL-certified and free from vulnerabilities. Your visitors won't stay on your site if they don't feel safe — so high security is non-negotiable.
