How We Score

Our audit scores are based on 70+ automated checks weighted by severity and prevalence. Issues are grouped by type, and each is scored based on how critical it is and what percentage of your pages are affected. This means a widespread warning impacts your score more than an isolated one, but the same issue appearing on 50 pages won't unfairly penalize you 50 times.
