Of course, your visitors can use third party tools like Google Translate or Babelfish to translate your site themselves, but you should never rely on users to do anything.Laziness is king on the internet, so always make things as easy as possible. Think how social media icons increase traffic even though users have browser bars and bookmarklets that they can use.Fortunately, you don’t have to hire a professional translator to support multiple languages on your site. Thanks to wonderful APIs such as the Google Language API, there are a number of free and easy-to-install translation solutions available. Although these automatic methods will never be as good professional translations written by translators, they provide an attractive opportunity to offer internationalization at no cost.
