Imagine, that visitor on your website speaks ジャパニーズ , عرب , Ελληνικά , יידיש , ગુજારાતી , हिंदी or even 中国人 . Actually this shouldn't be a problem, while english is considered to be international communication standard and most people , who serf internet have this or that command of it.
Though, if you may want to make life easier for your guests and make your services more understandable, you may want to imploy Google translate button, that will offer content of your site to foreign guest in his language.
There are small issues about this. Always check result, after Google translated your content. Approach ist't yet perfect and sometimes good idea were to simplyfy original text to make result look better. Pieces of text , that you do not want to be translated, should be provided with 'notranslate' class.
<div id="google_translate_element"></div>
<script type="text/javascript">
function googleTranslateElementInit() {new google.translate.TranslateElement({pageLanguage:'en'}, 'google_translate_element');}</script>
<script src="//translate.google.com/translate_a/element.js?cb=googleTranslateElementInit"></script>
After that guest gets button with available languages.
