A Shopify store with 709,510 sessions and 20,209 completed checkouts in the period shown.

Traffic grew 89% while completed checkouts grew 298%, so the store converted more of a larger audience instead of diluting it. Checkout reach growing faster than add to cart, and sitting above it, often points to more shoppers using express checkout buttons that skip the cart. Each step of the funnel grew faster than the one before it.
Calls are for stores doing $20k+ a month.
