Redirects or duplicates of websites with multiple TLD languages

hreflang: The HTML attribute for multilingual websites

The main reason for using attributes like canonical or hreflang is that Duplicate contentshould be avoided in multilingual web projects. Often different markets are to be served without the content - with the exception of the translation - fundamentally differing. For countries that speak the same language, the situation is even more complicated: unite few changes due to cultural or regional differences (vocabulary, currency, contact information, etc.) are here mostly identical content across from. Since the same domain is usually used, it is of great importance to send the search engines clear signals in order to prevent a negative rating.

While the canonical attribute declares a URL to be the dominant variant and excludes all alternative versions from indexing, the hreflang attribute signals which version should be presented to a specific target group (language and / or country) in search engine research. For this reason, the HTML markup is always suitable if you want to be internationally successful with your website and have the corresponding multilingual content. Even if the attribute has no direct influence on search engine ranking, correct use will pay off in the long term because both crawlers and users in different countries can better track your website.
