Give Claude a URL. Get a scored, plain-English report with specific fixes and time estimates.
You give Claude the URL. Claude scores it across 6 dimensions using the same frameworks professional UX consultants use. The report tells you exactly what to fix, how long it will take, and why it matters. You do not need any background in UX, conversion rate optimization, or web design to act on the results.
| Dimension | Weight | What it means |
|---|---|---|
| First Impression | 20% | Can a visitor understand what you do in 3 seconds? |
| Copy and Messaging | 20% | Is the writing clear, jargon-free, and benefit-focused? |
| Call-to-Action | 15% | Is the CTA visible, compelling, and the only clear next step? |
| Trust and Social Proof | 15% | Are there testimonials, logos, numbers, or guarantees? |
| Mobile and Accessibility | 15% | Does the page work on phones? Can everyone use it? |
| Performance and Technical | 15% | Does it load fast? Are the SEO basics covered? |
Every finding includes: what is wrong, why it matters, the specific fix, and a time estimate.

This skill does not score based on opinions. Every dimension maps to a published, peer-reviewed, or industry-standard framework.
Nielsen's 10 Usability Heuristics - Jakob Nielsen, Nielsen Norman Group, 1994. The most cited usability framework in existence, used by every major UX team in the world. It gives the audit a principled checklist for identifying confusion, inconsistency, and friction before a user ever bounces.
StoryBrand Framework - Donald Miller, 2017. Clarifies messaging by placing the customer as the hero of the story. It explains why most landing pages confuse visitors instead of converting them, and gives Claude a structured way to diagnose that confusion.
CRO Pyramid / LIFT Model - WiderFunnel. Breaks conversion down into 6 factors: Value Proposition, Relevance, Clarity, Anxiety, Distraction, and Urgency. Informed by thousands of A/B tests across real campaigns, it keeps the scoring grounded in what actually moves the needle.
WCAG 2.2 AA - W3C Web Accessibility Guidelines. The international standard for web accessibility. Ensures your page works for people with disabilities, and keeps you on the right side of accessibility law.
Core Web Vitals - Google. Google's official performance metrics: Largest Contentful Paint, Interaction to Next Paint, and Cumulative Layout Shift. Slow pages rank lower in search results and convert worse.
Baymard Institute Research - 130,000+ hours of UX research on real users. Informed the trust signal and CTA scoring criteria with data from studies on how real people read, click, and abandon pages.
Different business types have different success criteria. Scoring adjusts for SaaS, ecommerce, course, agency, newsletter, and early-stage or pre-launch products. A page with zero testimonials scores differently for a day-1 launch than for a product that has been live for 6 months.
