What Is a Website Grader?

A website grader is an automated diagnostic tool that scans a website URL across multiple digital quality dimensions and computes an objective overall health score (from 0 to 100). It benchmarks your site's performance, search engine readiness, user experience design, mobile responsiveness, and conversion architecture against industry standards, giving you an immediate prioritized summary of what needs improvement.
