After searching through Google using keywords “Website Inline Translation using Google Translation API”, I could not really find out the easy way to help website with translation implementation. And eventually, I found that there is the “Website Translator” that can instantly translate website text to any desired language, and it is provided by Google as translation web service.
The Google Website Translator is located here:
There are only about three steps to get the embedded code to be inserted in header and translation language switcher area.
The output will look like this:
The language switcher is located on the top right corner.
This solution is fast, but it does not take care of translation accuracy. In order to have good translation result, we can choose PO Edit to edit to-be-translated text into translated text stored in PO files in different languages.
Hope this helps with your site translation.
