How Your DCI Score Is Calculated

Your website’s DCI Score is calculated based on its performance across three categories: Quality Assurance, SEO, and Accessibility. Each category makes up one third (33.33%) of your overall DCI Score. When combined, they give you a comprehensive overview of issues across all three categories, highlighting issues that need to be fixed and providing recommendations on how to fix them.

Quality Assurance – This reflects your website’s credibility and trustworthiness regarding its user-facing characteristics.
SEO – This shows how well the user-facing and technical aspects of your site contribute to search engine optimization, and ultimately, higher rankings and organic traffic.
Accessibility – This demonstrates how well your website tests against web accessibility standards set out in WCAG (Web Content Accessibility Guidelines) 2.0.
