I just done a full analysis of Google's SERPs vs Bing's SERPs and how much ad space they occupy.
Here are the screenshots:
All-in-all, on a 1280x1024 screen resolution, and searching for [credit -site:google.com] (which hides the Google comparison bar), there are 1,066,250 used pixels in the overall Google layout (meaning not including the whitespace to the right, or the menu bar, etc). 268,800 of those pixels are taken by organic SERPs. 336,750px are taken by paid-for adverts.
This amounts to 25.2098% of the interface being taken up by organic SERPs, whilst paid-for ads take up 31.582% of the interface.
On a 1920x1080 screen resolution, and this time showing the comparison tool in Google's SERPs, the results are even worse: 21.79459% for organic SERPs, versus 38.4165% for paid-for ads.
How does this compare to Bing? Well, on a 1920x1080 screen resi, 1,036,950 pixels are used up in the overall interface
369,000px are used up by organic SERPs, versus 252,952px for paid-for ads.
This comes out to 35.5851% for organic SERPs and 24.3938% for paid-for ads.
Yes, I was bored ;-) (Plus I started doing this quickly, then realised I may as well flesh it out into a more full article which I'll post up on one of my sites soon)
[edit reason] Added screenshots [/edit]
