Global SEO Right: Localization, Hreflang, Currency

Product‑led companies often discover that international demand exists long before their site and storefront are ready for it. The payoff is real. According to CSA Research, 76 percent of online shoppers prefer products with information in their native language and 40 percent will never buy from websites in other languages. Turning that demand into revenue requires more than translation. You need a tight architecture for localization, discoverability, pricing, and performance.

Step 1: Decide language vs region and pick the right URL model

Start by separating language and geography in your plan. A site can be multilingual, multi‑regional, or both. Google’s guidance on managing multi‑regional and multilingual sites clarifies the difference and recommends distinct URLs for each language version rather than swapping content with cookies or headers. Google also explains the pros and cons of ccTLDs, subdomains, and subdirectories, noting that ccTLDs send strong country signals while subfolders and subdomains are easier to operate at scale.

If you choose dynamic routing, remember that Googlebot usually crawls from the United States and does not set Accept‑Language. As Google notes, auto‑redirects based on perceived language can block discovery. Always give users a visible language and country switcher.

For modern frameworks, Next.js internationalization supports sub‑path or domain based routing and locale detection in Middleware. That pattern scales well across regions and keeps routing explicit for SEO and analytics.

Step 2: Implement hreflang the way Google expects

Hreflang ties your localized URLs together so the right version ranks and appears in search. Google’s localized versions documentation is clear. Every variant must reference all other variants including itself, use fully qualified URLs, and provide an x‑default for unmatched languages. The same page outlines common mistakes like missing return links or invalid language and region codes. Follow ISO 639‑1 for language and ISO 3166‑1 Alpha‑2 for region, for example en‑GB or de‑CH.

If you are on Shopify, Shopify’s developer docs confirm that Shopify automatically injects hreflang via content_for_header and generates locale‑aware URLs such as /fr or /en‑ca. You still need a visible selector, and you should avoid hardcoded links so shoppers do not fall back to the default market.

Step 3: Localize pricing and payments that actually convert

Language earns the click. Price and payment methods seal the deal. Stripe’s analysis of 50 plus global payment methods found that dynamically surfacing at least one relevant non‑card method yielded an average 7.4 percent conversion lift and 12 percent more revenue. Local dominance matters. Offering Alipay in China increased conversion by 91 percent and iDEAL in the Netherlands by 39 percent in Stripe’s tests.

Friction at checkout still kills many carts. The latest Baymard Institute data shows 39 percent abandon due to extra costs and 10 percent due to not enough payment methods. Reducing currency surprises, pre‑calculating duties, and offering familiar payment options are all conversion levers.

For Shopify stores, Shopify Markets lets you configure market specific domains or subfolders, translations, and international pricing. The same documentation explains presentment currency, where the price a buyer sees and pays is the source of truth. If you need more control than automatic conversion with rounding, Shopify supports price lists and per‑market overrides so you can set true local price points. If you are choosing a platform, Shopify streamlines multi‑currency, localized URLs, and payment method coverage without heavy custom code.

Step 4: Build a multi‑region architecture that is fast everywhere

International SEO depends on fast delivery. Google has replaced First Input Delay with Interaction to Next Paint as the responsiveness metric in Core Web Vitals, and Google’s announcement confirms INP became a Core Web Vital in March 2024. Treat INP, LCP, and CLS as success criteria for every locale. That means static generation where possible, sensible caching, and minimal blocking scripts.

Edge logic helps route users to the right experience without hiding content from crawlers. Cloudflare documents IP geolocation headers and shows how to implement country‑code redirects with Workers. Use this carefully. Avoid unconditional redirects that prevent discovery of all locales. As Google’s international guidelines warn, you should provide language and region links on page and avoid automatic redirects that block users and bots.

If you are shipping a headless or hybrid app, Next.js i18n routing makes it straightforward to map locales to subpaths or domains, preload translated content on the server, and keep bundles lean. Pair that with a CDN and an image optimization pipeline to hit Core Web Vitals across regions.
