How do you improve conversion rate on mobile?
Remove steps rather than adding persuasion. The mobile gap is almost never a copy problem — it is typing an address on a phone, signing in, and re-finding a product that was open yesterday.
What decides it
In order of yield: wallet payment so nobody types a card, saved addresses, a search that tolerates misspellings, and the delivery date shown before checkout rather than after.
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.
