In this week’s Internet Marketing Podcast Andy talks to Joost de Valk about internationalisation. Joost talks about his recent involvement in the migration of The Guardian’s website from a .co.uk domain to a .com domain to satisfy its growing global audience. He discusses the differences between internationalisation and localisation, and how to get the most from each form of optimisation. Finally he gives some advice for small businesses about how to localise a site and gives some recommendations on optimising it for global audiences.
