Shopify mobile optimisation is not shrinking a desktop page. A cross-border store should design for one-hand use, network, device, media, fonts, checkout, payment, address, language, and accessibility and remove errors that block purchase. Measure mobile tasks by device and market without promising a fixed conversion lift.
Page and interaction
Keep clear hierarchy, target size, and state feedback for product, search, filters, variants, cart, and checkout. Load media and scripts as needed; fonts and pop-ups must not cover price, stock, delivery, or CTA. On a weak network, show loading, retry, and error paths.
Checkout and cross-border
Test address, postcode, phone, currency, tax, shipping, payment, discount, language, keyboard, and screen reader. On payment failure or return, preserve cart and prevent duplicate charge; disclose market-specific delivery and payment before purchase.
| Task | Check | Evidence |
|---|---|---|
| Browse | Navigation, search, media | Device sample |
| Product | Variant, stock, price | SKU test |
| Checkout | Address, payment, tax | Order sample |
| Access | Keyboard, contrast, reader | Accessibility record |
SEO and GEO
Keep clear title, H1, canonical, visible text, and structured data and answer device, speed, payment, address, language, and error questions in FAQs. Do not promise from one PageSpeed score or mobile ranking. Use Shopify SEO context for page governance.
Acceptance
Test home, collection, product, search, cart, and checkout by device, browser, network, market, and language and record error, latency, and manual work.
