However, what if you place 160-600 size ad unit vertically next to the article body. As people are reading down the lines they will see more adsense ad exposure with 1600-600 than 300-250.
Any thoughts or serious research about this topic?
But it should be easy enough to test - design two pages, one with the 160x600 and one with the square, serve them up randomly, and see what you get.
As far as the question of whether advertisers prefer 300 x 250 to 160 x 600, that probably doesn't matter unless you're using Google for "image ads" (display ads). If you limit yourself to text ads (the AdSense default, as I recall), advertiser preferences shouldn't be an issue.
