The best way to make your site international is to have access to a translation application visible. I don’t do this myself because I keep a translator from Google in my Chrome web browser. A simple solution. People who only know one or few languages should be prepared to encounter other languages. It is then their choice to translate, run away or ignore them. Of course, it depends on how interesting and well put together the site looks, that first impression.
Trying to cater to multiculturalism, global protocols, and international readers is a good thing, in moderation. But, you can’t possibly include everyone.
Instead, identify your own location. Show where you are from and who you are. Some of your readers will be happy to find they have something in common with you (at least geographically) and others will be interested to know more about your culture, history, traditions and point of view.
The advice given with this post (link below) is mainly cosmetic. Design and colours can make your site have more international or global appeal but I don’t think keeping it neutral is really in your best interest. Boldness, drama and colour will do more for your site than becoming neutral or bland.
