I have looked at a lot of different hubs, (I actually spend a fair amount of my time on hubpages reading other peoples hubs) and have seen a wide range of different placements. When just looking at hubs, there's no way to tell if amazon placement is strategic, or just thrown in willy-nilly as I am doing.
I asked the question because I'm curious about different people's (effective) strategies behind their ad placement. I'm more interested in hubs that specifically target a certain placement, rather than just any old hub with amazon capsules.
I also thought others might be interested in hearing peoples opinions on the matter.
