CRO & Analytics: The Complete 2026 Guide
Traffic is expensive; converting more of it is free margin. This is the full system for lifting conversion and actually trusting your numbers — testing, landing pages, GA4, and attribution in a privacy-first world.
CRO lifts revenue from traffic you already paid for — often the highest-ROI work in marketing. Run a disciplined testing program (most tests fail on process, not ideas), fix landing-page conversion, set up GA4 + server-side tracking correctly, and accept that attribution is now modelled, not measured. Optimize the funnel before buying more traffic.
