What Is Hreflang?
Hreflang is an HTML link attribute (<link rel="alternate" hreflang="x" href="...">) that specifies the language and optional regional targeting of a page. It tells search engines about equivalent pages in different languages so they can serve the right version to users.
Why Hreflang Matters for International SEO
Without hreflang, search engines may treat your multi-language pages as duplicate content and only index one version. They may also serve the wrong language version to users. Hreflang solves both problems by establishing relationships between language variants.
How to Implement Hreflang
Add hreflang annotations to every page using <link> tags in the head, HTTP headers, or XML sitemap. Every page must reference all its language variants including itself (with an x-default fallback). Annotations must be reciprocal. Validate with CrawlBeast.
