In an effort to follow google adsense's policy of not pushing content down the fold with use of a very wide ad unit, I decided that on my webpages, I use only square ads so that text is around the ad unit and then the ad unit becomes less intrusive.
I'm also doing this on the mobile version of my site.
My question is what is the maximum width of a screen an adsense ad unit can take before google believes it pushes too much content down the fold?
I feel if I use too low of a width for ads, they wont be clicked on and I'll make no money. I also feel if I use too high of a width, then I could possibly push too much content below the fold.
Is there a special number (width percentage) I should go with here?
