What is hreflang and why do I need it for a multilingual website?

Hreflang is markup that tells Google which language and regional version of a page to show in search results. Without it, international visitors may see the wrong language or your translated pages may not be indexed correctly. Seatext automatically creates localized subfolders and includes valid hreflang tags for each language version. This is a core part of translating a site without losing international SEO.
