Hello husdawg and NilsC,
It sounds like you may be seeing an expanded text ad, which can be
either a placement-targeted or a keyword-targeted text ad.
Placement-targeted text ads always expand to fill the entire ad unit,
while we may expand a keyword-targeted text ad when we determine that
a larger ad will perform better for a particular page.
If you would like to find out if you are displaying placement-targeted
CPM ads on your site, follow the instructions here:
To find our more about placement targeting, please see our Help
Hope you find this information helpful,
