This might be something that some SEOs never really think about or consider, but are websites written with particular languages ranking better because it was written in that language? Naturally, if the goal of your business is to reach people who speak a particular language or languages, your content should be written for those languages.
Of course, if you write your content for English speakers, your site won’t rank very well for other language markets, such as Spanish, Chinese, French, and others.
If your particular company is able to pull business from multiple specific countries where the languages are different, then you want to make sure you create content in all of the languages you market to.
But a good question remains – can using different languages really affect your organic search rankings? Kristi Hines wrote a post on Search Engine Journal where she lets us know if Google considers language as a ranking factor.
