The Conversion Optimization Loop

Higher-converting pages with read-only-safe live measurement baked in. HubSpot gives Claude the customer/funnel data, the official GA4 MCP gives the real conversion numbers (read-only), page-cro diagnoses, copywriting rewrites, analytics-tracking instruments the new events, pricing-strategy tunes the offer, and Amplitude confirms what worked. Google's read-only GA4 server means Claude can't accidentally break your tracking.
