Compared to the single ad placement, this ad will contain two
unique ad's within the same placement.
This ad is extremely effective on blog and news type sites.
This ad is also a great tool for those
who also want to split test two different ads at the same time.
This add has hover effects that are similar to the single ad style.
Obviusly due to the fact that there is two ad's within the same space
you are restricted to less customization due to the trade off of having
two ads within the same space.
