cro-audit

Use when running a conversion rate optimization audit, analyzing funnels, identifying conversion blockers, or creating a prioritized CRO action plan. Also use when analyzing behavior data from Clarity/PostHog or measuring conversion baselines.

Overview

Diagnostic-first conversion rate optimization — 8-phase pipeline from baseline measurement to prioritized execution. Pull the data, watch real sessions, map the funnel, audit trust signals, and surface the highest-impact fixes. Never guess what to change — every recommendation is backed by data.
