Alternative to Google Adsense content injector module I want to "float" ads in the top right of my nodes for which Content Injector was nice enough in D6 moreover such ads convert well in my experience. 

But for D7 is there any easy alternative? I know I can sub-theme and place the ads in appropriate positions.
It might not be quite as versatile, but the Block Inject module will allow you to embed adsense blocks within the node body.
