Gotta agree with everyone else on this one . . . using banners all by themselves is a dead art. You need to step up the creativity level and start mixing the graphics with catchy text and your CTR will take a jump.

We use a mix of both, text+banners and text only. However we have found it very beneficial to learn your traffic then design creatives to meet their needs - it is then you will see an explosion in CTR on your ad spots.
