Conversion Rate
The percentage of store visitors or website sessions that result in a completed purchase.
Full Definition
In retail analytics, conversion rate measures the effectiveness of a store or digital channel at turning browsers into buyers, calculated as the number of transactions divided by the total number of visitors or sessions, expressed as a percentage. It is a primary KPI for both brick-and-mortar and e-commerce retail environments. Analysts segment conversion rate by channel, category, time period, and customer cohort to diagnose performance gaps. Editors should note the term is two words, unhyphenated, when used as a noun phrase; it takes a hyphen only as a compound modifier (e.g., 'conversion-rate optimization'). Do not confuse with 'attach rate,' which measures add-on or accessory purchase incidence.
Usage
Usage note: Expressed as a percentage, not a decimal, in retail analytics publications. Always clarify the denominator (visitors vs. sessions) on first reference.
