Testing Banner Ads
The problem is, when I enable each adgroup. I leave it for a couple of days, come back to check my stats and Google has decided to pick maybe 2 or 3 of the designs and give them all of the impressions, so I'm left with another 15 designs that aren't getting shown.
Any idea why? Each adgroup has exactly the same keyword list, so I'm a little stumped as to why.
At the moment, I'm resorting to just displaying one adgroup per day and pausing all the others. As you can imagine it's pretty slow going.
Any ideas guys?
