I'm trying to figure out what the value of a top ranking ad spot is besides traffic volume. Do they convert better? Do page 1 ads have higher CTRs and conversion rates than page 2 ads of the same position on screen?
Otherwise, with everything else held equal, upping your bid to increase rank (and thus number of clicks) would have the effect of increasing revenue but lowering ROI. But clearly there must be good reason for so many people to compete over the top spots. Or they're simply happy to have a lower ROI in exchange for a higher dollar amount of profit.
So, can anyone share their experience of what top ranking spots did (or didn't do) for them compared to lower ranking spots?
