Step 3: Use Hreflang Tags to Target Languages
Hreflang tags are bits of code that are used on websites that include material in various languages. They assist search engines in matching the appropriate language with the searcher. French speakers, for example, will view your French material rather than your English or Italian content.
How does Google determine what language a user prefers? Of course, the terms entered by the searcher are important cues. Google, on the other hand, considers data such as the user’s settings, search history, location, and which Google domain they are using (Google.com vs. Google.de, for example).
When offering translations of your content in subdirectories or subdomains, the hreflang tag comes in handy. While search engines can usually detect the language of a page without the use of hreflang tags, the tags assist keep your different page versions from competing in search results. Because of the signal from the country code, hreflang tags are not required when using different domains (ccTLDs).
