What is E-commerce conversion rate?

E-commerce conversion rate is the percentage of online store visitors who complete a purchase, calculated by dividing total transactions by total sessions. It is one of the most important metrics for online retailers and is directly influenced by product imagery quality, page load speed, pricing presentation, and trust signals. Product photos showing items in context with people consistently outperform white-background-only shots in conversion tests. Improving conversion rate by even fractions of a percentage point can translate to significant revenue gains at scale.
