As a long-term subscriber I would like to ask for your advice concerning optimisation of an e-commerce site for multiple countries. Specifically I am in the UK and have a client in Australia operating an e-commerce site. The site is well established and ranks well in the UK (where it is hosted) but not very well in the USA or Australia. My client believes this is because the site is hosted in the UK and that in order to succeed in the bigger US market he needs to host in the USA (same for Australia). He is asking if he should operate 3 sites – one hosted in each country – and I wondered if you could comment on the importance of hosting in the target country, and the implications of having what will essentially be 3 duplicates of the same site – one for .co.uk, one for .com and one for .com.au.
