A multilingual market rewards sites that get internationalisation right. That means locale-prefixed URLs, complete hreflang alternates, and translated metadata — not just translated body copy.
Performance is a ranking factor and a conversion lever. Ship server components, lazy-load below the fold, optimise images, and keep the hero text in the initial HTML.
Measure everything. Core Web Vitals, scroll depth, and CTA clicks tell you what to fix next — and prove the work paid off.
