If you write your blog in one language, don’t expect only people who know that language to stop by. Some visitors to your website may not understand the language you write in.
In such cases translation tools help those readers to convert the webpage into a language they understand. This makes reading information much more easy for them.
There are several ways in which you can offer translations to your users. If you are looking for a even better tool, Google has just announced a website translator gadget that is definitely much more smarter than the regular ones right now.
To install the website translator gadget to your blog, visit this page and copy the text to the header of your template.
After you have copied the text to your template upload the file to your server for the changes to take effect.
Once the code is in place, Google will automatically detect the users language based on the browser settings and display an option to translate the page to their language.
Once they click on the translate button the webpage will be translated without the user leaving your site. Google Translate currently supports translation between 51 languages making it a good fit for webmasters with traffic from several countries.
