Why do you want to translate your blog/website in different languages? I know it is the fact that people from all over the world will search in Google, Yahoo!, MSN or other search engines and they might find your blog/website not in their native language. How can they understand what your contents are all about? Therefore, it is necessary that you provide them a translation tool so that they can translate your blog/website by simply clicking on their corresponding country flag.
You can get a Google Translator Widget here. So far this widget can translate your blog/website from English in other ten languages: Arabic, Chinese, French, German, Italian, Japanese, Korean, Portuguese, Russian, and Spanish. After you've got the widget code, following the steps below to implement it in your New Blogger:
- First login to your Blogger's Dashboard.
- Second click on Layout.
- Next click on Add a Page Element.
- Then a new window will pop up.
- Find HTML/JavaScript and click on Add to Blog.
- A new window will just pop on top of the other one.
- Put the code you've got earlier in the content area and give a title if you wish.
- Click on Save to save it.
- Move the widget wherever you want it to be
- Finally click on Save which is on top of your New Blogger's layout.
