Scoring Web pages for Usability at scale
Reduced experiment planning time from 1–2 hours to 10 minutes by building an AI-powered workflow that translates stakeholder ideas into structured test plans.
THE PROBLEM
UX audits were:
Time-consuming (2–3 hours per page)

Often delayed or deprioritized because of effort required
For my team, the cost was:
Missed optimization opportunities
Reliance on subjective opinions instead of structured evaluation
My Role
As the Lead UX Designer, I…
Defined an evaluation framework (heuristics, structure, scoring)
Designed prompt architecture + agent workflow
Built and tested agent in Microsoft Copilot Sudio

Using the rubric provided in the instructions and topic, agent will evaluate and score the page in the following categories:
Content Quality & Information Design (max 30 points)
Visual Layout & Hierarchy (max 20 points)
Interaction & Task Support (max 25 points)
Navigation & Wayfinding (max 15 points)
Accessibility & UX Fundamentals (max 10 points)
Agent outputs scorecard

Scorecard organized by categories above with the following:
Category score
Key issues
Prioritized recommendations
THE IMPACT
Reduced audit time: 2–3 hours → ~10 minutes
Increased consistency across evaluations
Enabled faster, data-driven iteration for websites
Scalable across multiple pages without additional effort
Final thoughts
Automating this process shifted UX evaluation from ad hoc reviews to a scalable system. The scorecards became a consistent starting point for discovery and testing, allowing us to quickly identify opportunities and support recommendations with GA4 and Clarity data.
