Of course this works, but i'd wager a guess and say that those are mostly US bloggers targeting US visitors. Once your visitors are from all over the world, it is indeed as the author described - there isn't a "proper" solution available (save for e.g. a WordPress plugin that generates the link on-the-fly but this approach has other problems like non-cachability). If there is indeed an approach that lets you monetize like 99% of international traffic/clicks i'd like to hear it.
