I have heard rumors that only the Top 3 ranked ads even make it to the content sites. My sites been doing well with content conversions. I'm wondering...if I raise CPC just a touch, and that gets me in the top 3 positions, will I see an explosion of traffic? Or is this an old wives tale about the top 3.
It is conceivable that a site has 3 blocks of ads on a single page - showing a total of 12 Ads (if there are enough advertisers) - it this were to be the case then more than the top 3 would be showing on content.
Nevertheless, I can well imagine that the top 3 dramatically outperform lower ranking ads on the content network.
