Calls to action: Are your site visitors doing the things you expect? Do people spend a reasonable amount of time on your site and is your site delivering the results you need?
Site load time and performance: Does your site have the right balance of graphic elements and responsiveness? Do people have time to get a coffee between page views?
Accessibility for users with disabilities: How accessible is the information on your website to users with disabilities? If you promote your organization as being an equal opportunity employer, how compliant is your website?
