How It's Calculated

Incorporating over 200 individual checkpoints, the Siteimprove Digital Certainty Index tests a website’s performance across three major categories: Quality Assurance, SEO, and Accessibility. The overall Digital Certainty Index score indicates the effectiveness of a website, while its sub-scores indicate how well it lives up to quality standards, how discoverable it is for search engines, and if it meets accessibility standards.

This comprehensive overview of your website’s current status also offers exact recommendations on how and where to improve your score. Each task is tied to a numerical value—so when you address these issues, you watch your DCI score climb.
