The goal

Sell in multiple countries without turning your site into a maze. For fashion & jewelry, that means clear currency, correct sizes, readable languages, market-specific info, and SEO that doesn’t duplicate everything.

Currency switcher (that shoppers actually trust)

Design patterns

• Location hint + manual control: auto-detect to a sensible default, but always show a visible switcher in the header or mini-cart. Never trap users.

• One label, one meaning: show currency code and symbol (e.g., EUR €), not symbols alone.

• Sticky choice: once a user selects a currency, persist it through PLP → PDP → cart → checkout.

• Rounding rules: avoid weird decimals (e.g., €49.90 → €50). Choose market-specific rounding.

Microcopy examples

• Cart note: “Prices shown in EUR. Taxes/duties calculated at checkout if applicable.”

• PDP bar (international shoppers): “Ships from EU warehouse. Typical delivery 4–6 business days.”

Do / Don’t

• ✅ Do show free-shipping thresholds in the selected currency.

• ❌ Don’t switch currency without the shopper’s consent mid-journey.

Sizing localization (EU / US / UK)

Fashion

• Dynamic size labels: map variant labels to the shopper’s region (e.g., EU 38 shows as US 6 with an info tooltip).

• Compact converter: “View size in: EU / US / UK” right above the size grid. Keep it one tap.

• Size guide per locale: fabric notes and model measurements should change with the language/region.

Jewelry

• Ring sizer flow: quick picker (US/UK/EU) + link to printable guide.

• Specs near price: metal, stone, carat—never in a collapsed tab.

Do / Don’t

• ✅ Do remember the last size system a user chose.

• ❌ Don’t bury the size chart; keep it within one tap of the size grid.

Language toggles (clarity over flags)

Patterns

• Text labels over flags: languages aren’t countries—use EN / DE / ES (with full name on hover).

• Header placement: near currency; keep both controls predictable and reachable on mobile.

• Copy length elasticity: allow headings and buttons to expand in DE/ES without breaking layout.

• Fallbacks: if a translation is missing, fall back gracefully (don’t show mixed-language screens).

Legal clarity

• Translate Terms, Privacy, Returns/Warranty, and imprint/company info per language. Link them in the footer per locale.

Shipping notes & legal pages (market-specific)

What to localize

• Shipping speeds & carriers by region (EU vs US vs UK).

• Taxes/duties: state whether you collect them or if they’re due on delivery.

• Returns language: fashion emphasizes size/fit; jewelry highlights care, warranty, and engraving policy.

• Contact details: local phone formats, business registry/VAT where required.

Placement

• PDP: short delivery & returns summary above the fold (expandable).

• Cart/mini-cart: threshold bar + returns teaser line.

• Footer: full legal pages per locale.

Region-specific content blocks

Where it helps

• Home hero & promo bar: region-specific shipping offers or seasonal campaigns.

• PLP banners: country-specific size guidance or “UK Next-Day available.”

• PDP badges: “Made in Italy,” “Hallmarked in the UK,” “2-Year Warranty”—toggle per market.

• Payments row: show the logos shoppers recognize (Shop Pay/Apple Pay/Google Pay/Amex) based on region.

Implementation tip (Shopify-first)

• Use Markets and locales to conditionally render blocks in the theme (no heavy app stack). Keep it simple and editorial-friendly.

Avoiding the SEO mess (clean locale routing)

Use subfolders, not parameters

• Prefer /en/, /de/, /es/ (and optionally /en-us/, /en-gb/, /en-eu/) over ?lang=en. Subfolders are clearer for users and search engines.

Hreflang done right

• On each localized page, include hreflang pointing to its siblings (and an x-default). This tells search engines which version to serve per user.

Canonicals

• Canonical each page to itself in its locale. Don’t canonical EN to DE or to a generic root.

Consistent slugs

• Keep product/collection slugs aligned across locales where possible (translate only when necessary) to simplify maintenance.

Redirects & UX

• Soft prompt on first visit (“Looks like you’re in Germany — switch to DE?”). Don’t hard-redirect without a visible choice, and always keep the manual language/currency controls.

Sitemaps

• Generate a sitemap that includes all locales. Submit in Search Console for primary domains.

QA checklist (5-minute sanity test on mobile)

• Currency switcher visible, persists through checkout.

• Free-shipping threshold updates in the selected currency.

• Size system toggle works; size guide opens fast.

• Language toggle visible; no mixed-language UI.

• PDP shows localized delivery/returns summary.

• Footer links to locale-specific legal pages.

• URLs use the correct /locale/ path; hreflang present.

How we ship this (Siteon approach)

We redesign the entire site—navigation, PLP, PDP, cart/mini-cart, and global components—then layer in locale controls that are simple to maintain:

• Header controls: language + currency (compact, consistent).

• Locale-aware size modules (fashion & jewelry).

• Market-specific blocks for shipping, payments, and trust badges.

• SEO-safe routing using subfolders and hreflang.
