What should you fix first on a store that is not converting?

Find the step where people leave before changing anything. Most owners redesign the home page when the loss is at checkout, and the redesign measures nothing.

What decides it

Look at the funnel by step and on mobile separately. If the drop is at product-to-cart it is a pricing or information problem; at cart-to-checkout it is cost or delivery; inside checkout it is friction.

The part that gets skipped

Retention beats acquisition on every measure, and almost every store spends the other way round.

The slowest part of most mobile stores is images nobody resized. It is the most common performance problem and the easiest to fix.

Discounting to grow trains customers to wait for discounts. It works once and costs afterwards.

Where an app fits

Push notifications are the one growth channel you do not rent. Every other route to a customer is paid for again each time.
