Multilingual SEO, also known as search engine optimization for multiple languages, aims to improve a website’s visibility in search results for different languages. This practice generally concerns global SEO strategies, but can also be applied to national contexts where several languages ​​are significantly used, such as in Switzerland, Belgium, or the United States.

The stakes and challenges of multilingual SEO are numerous: they include ensuring the quality of translations, which not only impacts search engine ranking but can also be penalized by Google for poor-quality content. Decisions regarding domains and extensions are crucial, as different versions may or may not be hosted under the same domain name. URL structure is also essential, often with an organization into directories corresponding to each language (for example: domain.com/fr/ for the French version).

Other aspects to consider include using tags or attributes to indicate language variations of a page, choosing the hosting server location, potentially declaring a target country in the search console if certain languages ​​are specifically intended for a given market, and much more. Multilingual SEO is part of a broader approach to internationalizing a website, where tools like the country targeting feature in Google’s search console can prove very useful.
