Getting hreflang right matters for international SEO, and the right approach depends on your setup. For multi-store, Hreflang Manager adds and maintains tags with automatic content matching, helping you avoid wrong-version landings, duplicate content, and lower SERP rankings. For Shopify Markets, it gives you one place to adjust and fine-tune the tags. Either way, it helps Search Engines clearly understand the relationships between your localized stores and their pages.
