Now I propose a new theory.
G intentionally reduced the number of ads in the 336x250 unit to two or one leaving a lot of white space and showing big fonts. This is exactly G want to achieve! Why? because most people including me blend the 336x250 into their content (this format blends best), misleading visitors to click the ads as part of the content. G must have got lot of pressure from advertisers about the blending, so G makes the ads in this format stand out.
The results are:
advertisers get real clicks but pay higher for each click
publishers get low CTR, but higher EPC.
Believe or not, let wait and see.
Now I propose a new theory.
Where would any of us be without a good theory?
That one sounds plausible. The thing that is behind all of this is either:
a) Google trying to combat ad-blindness, en masse, or
b) Google trying to increase the justification for charging more per click for the advertiser, in exchange for adblock formats that deliver better conversion rates.
