I'm using custom keys in DFP to segment my website based on category. For some of these categories, I'd like to serve a 300x600 ad unit in the right-hand sidebar. For others, I'd like to stick with the 300x250 unit. (I'm assuming that when I serve the 300x600 unit, it'll push other elements in said sidebar downwards, which is fine.)
My thought process for achieving this is: 1) Create a 300x600 ad tag in DFP 2) Place this ad tag in site code within the appropriate in the sidebar 3) ?
...so, I'm not sure where this new tag needs to be placed and (equally important) how to prioritize the 300x600s to essentially serve ahead of what are typically run-of-site campaigns to the 300x250 units.
Let me know if I can provide any more info, not sure how clear this is.
Thanks to everyone in advance, J
