How is website redesign success measured across UX, SEO, and conversions?

Website redesign success is measured by comparing post-launch performance against documented pre-launch baselines across three domains. UX success is measured by improved task completion rates in usability testing, reduced bounce rates, increased session duration, and lower exit rates on key conversion pages.

SEO success is tracked through keyword ranking stability or improvement (monitored in Semrush or Ahrefs), maintained or increased organic impressions in Google Search Console, and Core Web Vitals score improvement for both mobile and desktop. Conversion success is measured by lead volume, form completion rate, CTA click-through rate, and, where CRM integration exists, lead-to-opportunity rate. A structured 30, 60, and 90-day post-launch measurement schedule allows teams to identify and address regressions before they compound into significant business impact.
