Google AdSense – how closely targetted is it?

On a lighter note than usual – it brought a smile to my face recently when I was working on a domain of ours which includes the word EARTH…

In adding some AdSense to the site and whilst testing without any content up on the right hand side pops something like… “Visiting Earth – For all you need to know visit Trip Advisor for everything you need to know about Earth”.

Perhaps they see the advantage of targetting any aliens about to visit and looking for reviews of hotels they can rest up in before the invasion? 🙂
