Google "Mostly" uses the same search algorithms for each language, but there are some algorithms that are only used in certain languages. Google uses the same search algorithms for most languages, but there are certain cases where the language requires a different algorithm to interpret queries.

He stated this Google-ov John Muller in response to the question: "Yes Google uses the same algorithm for each language? ”

The question further goes on about ranking factors and SEO practices and how they can vary from one language to another.

Specifically, the question is:

"Updating BERT had to do with semantics, so it made me wonder if it would be the same in every language. Which then led me to think about other ranking factors and how their significance may differ between different languages ​​/ cultures. Anyway, I want to ask anyone with experience in SEO in another language, did you find any differences between the ranking factors? ”


Mueller does not touch on the aspect of ranking factors, but deals with the use of search algorithms in different languages.

Read his full answer in the section below.


How Google's search algorithm varies by language

Although many algorithm Google called searches a single entity, it really consists of "lots and lots" of algorithms.

Some of these algorithms are used for searches in all languages, while some are used only for individual languages.

Mueller says, for example, that some languages ​​do not separate words with spaces. Therefore, it is necessary to use a different algorithm than the one that Google used for languages ​​that use spaces.

"Mostly. Search uses many, many algorithms. Some of them apply to content in all languages, some of them are specific to individual languages ​​(for example, some languages ​​do not use spaces to separate words - which would make it difficult to search if Google assumes that all languages ​​are similar to English).


How Google Search understands content in different languages

As for search Google-and in different languages, it is worth mentioning the issue that was raised during Google Search Central Search Engine Optimization last week.

Mueller was asked how Google determines when one page is similar to another when each page has content in a different language.

Briefly, Google cannot detect when part of the content in one language is the same or similar to part of the content written in another language.

Google relies on content publishers to identify that multiple pieces of content are equivalent when written in different languages.

This is achieved using the HTML attribute hflange, explains Mueller:

"We basically use hreflang to understand which of these URLs are equivalent from your point of view. 

… I think it is impossible to understand that this specific content is equivalent to another country or another language. For example, there are so many local differences that are always possible. ”


Knowing that Mr.Oogle it cannot determine the equivalence of the content of different languages ​​on its own, it sheds more light on why Google has certain algorithms for certain languages.
