Welcome to the Q&A Forum

Thanks guys, great insights! @Nick I do have multiple ccTLDs for the same site. The content for each, however, will be significantly different. By 'domain-mapping' I meant actually getting into the DNS records and mapping the ccTLD URL to a sub-domain Rel canonical redirect: I'm assuming that the .com.uk would be the canonical page? If this page is the canonical page, and the com/uk/ is the 'discounted' page, what happens if the rest of the site uses the .com/uk convention? (In other words, is it advisable to have this inconsistency [both from a usability, index point-of-view]?) @Gary I think this is a very interesting point. I agree with both of you that if I saw a billboard for domain.com/uk, I might think it to be slightly odd. However, I'm not sure if consistency trumps familiarity or not. Further down the rabbit-hole: I will have multiple languages (let's say en, fr, es). I want this to utilise sub-directories (I want to avoid super-fancy AJAX whatnot. I HATE Google's help page URLs, for instance). domain.com/us/en/ domain.com/us/es/ The idea here is that the site rank for multiple languages, within a country (without creating super-duper long URLs). Any ideas/tips? Maybe a quick outline might help: 1 - Main (sort of a splash/navigation page) 1 -  USA 1 - EN 2 - ES 2 - UK 1 - EN 3 - France 1 - FR 2 - EN
