How do you increase conversion for grocery in the GCC?

Usually not on the product page. Measure the funnel by step and the loss is nearly always at checkout — address entry, payment method, or a delivery estimate the customer did not expect.

Where the drop-off actually is

The single highest-yield change for most stores in this market is showing the delivery date before checkout rather than after. It removes the reason people leave to go and check.

Winning a customer costs money and selling to them again costs almost nothing, and most budgets are spent as though the reverse were true. For a grocery or food store in the GCC, the answer turns on one thing in particular: Grocery margins are thin and baskets are large, so the whole model lives or dies on delivery cost per order.

Where a mobile app comes into it

Weekly reordering is the behaviour, and an app that remembers the last basket removes most of the work.
