Most "CRO" is guessing with extra steps: change the button color, run it for a week, declare whatever's ahead the winner. Real landing page optimization starts with evidence — session recordings, heatmaps, scroll depth, funnel drop-off analysis, exit surveys, and review mining — to find out where and why visitors leave. Only then do we form hypotheses worth the traffic it costs to test them.
Every test we run is sized for statistical validity before launch (minimum detectable effect, required sample, expected runtime) and measured on revenue per visitor, not just conversion rate — because a CVR win that drags down AOV or LTV is a loss wearing a costume. Winners ship permanently; losers teach us something and die. On retainer engagements this becomes a compounding loop: our pet health client ran 50 tests, shipped 13 winners, and added an estimated $277K in monthly revenue.
