I'm wondering if AdSense is the best advertising platform to use for international/multi-lingual websites. When trying an AdSense sandbox preview tool, I have noticed that for example the Chinese version of the site shows some Chinese adverts, but mostly they are English. I have tried searching for "Chinese alternative to AdSense" but can't find anything specific to a region. I suppose I could just try this top 10 list, and see which performs the best?
