What problem does it solve? When facing open-ended CRO questions like "where do I start" or "why doesn't my site convert," teams often jump to redesigns or random optimizations without diagnosing the root cause. This Skill provides the psychological and strategic framework from Dylan Ander's Billion Dollar Websites methodology to diagnose which of the Five Pillars (Offer, UVPs, Copywriting, Creative, UI/UX) is actually failing before recommending any fix. ## Core Features & Use Cases - Five Pillars Diagnosis: Classify any conversion problem into Offer, UVP, Copy, Creative, or UI/UX failure, with MCP data signals mapped to each pillar. - Gator/Judge Psychology Model: Apply Kahneman System 1/System 2 thinking to evaluate whether page elements trigger hesitation or enable frictionless purchase decisions. - Redesign Pushback with Data: Counter redesign-first thinking using the empirical finding that only 1 of 20+ studied redesigns outperformed incremental testing. - MCP Recipes: Two executable recipes using Heatmap MCP tools (get_raw_pageview_analytics, get_raw_event_analytics, get_pageview_analytics) to triangulate the failing pillar from scroll depth, RPC, and RPS data. - Use Case: A user asks why their beautiful landing page has high engagement but low sales. The Skill guides analysis of the engagement-to-revenue ratio to detect Judge-activation pages, then maps the signal to the failing pillar. ## Quick Start Ask Claude to diagnose which of the Five Pillars is failing on your landing page using last month's heatmap analytics data.
