Over the years we have built a number of multilingual sites for international businesses and charities.
With a well planned site structure new language versions can easily be rolled out. Where possible we try to optimise code and images so common files can be updated across all language versions.
On the Shelterbox site we have built a CMS that allows their head office to update global information and their territories can translate this and add their own local information.
For the 1GOAL web site we used an IP database that allowed us to target not only language but adapt content based on the countries ISO3166 code (de, it, es etc.). This meant that a viewer in Portugal would see the site in Portuguese but show an image of Eusebeio while a viewer in Brazil would see the site in Portuguese with an image of Pele.
