Your ecommerce conversion rate is a fraction. The numerator is visible. The denominator is not.
Completed transactions divided by sessions. Clean. Simple. Trackable. The number your team reviews every Tuesday and your board sees every quarter.
What that number cannot show is the commercial quality of the intent sitting inside the denominator. The sessions generated by broad upper-funnel activity that were never likely to convert and are suppressing the rate by volume. The high-intent sessions lost at a single friction point that would have converted under a marginally different journey design. The returning customer treated as a new visitor by an attribution system that cannot distinguish them.
A conversion rate that is not broken down by intent quality, traffic source type, customer cohort and journey stage is a fraction whose denominator is doing most of the work. The businesses that improve conversion meaningfully do it by understanding the denominator, not by optimising the numerator.
