hreflang

What it means

For a prop firm with translated sites, hreflang links each page to its equivalents, such as English, Spanish, Portuguese and Arabic, using language codes and optional region codes, plus an x-default for everyone else.

Annotations must be reciprocal: every version lists every other version, including itself. Missing return links and wrong codes are the most common errors, and they cause the wrong language to rank.

Translation also has compliance implications. Rules, terms and disclosures must say the same thing in every language, and restricted countries apply regardless of language.
