There are a few things to avoid when doing Multilingual SEO, they are as follow:

  • Do not assume that Google is the only search engine used by world demographic. Baidu is the most used search engine in china and Yandex is most used in Russia, even over Google.
  • Don’t ever put two different languages on the same page.
  • Don’t use automatic translation software to convert your pages.
  • Don’t assume that the same word means the same thing in different countries.
