SEM Ad Text, What to Test First?

ad text

I’m starting work on develop an SEM campaign and in the process of writing copy started wrestling with some different testing options for the ad text.  My testing options are limited in two ways.  First, we’ll also be conducting an A/B landing page test for each ad group shortly as soon as possible once the campaign launches.  Secondly, since it’s a new campaign we intend to ramp up slowly so the initial focus will be on the long tail, greatly limiting our volume and quest for statistical significance.

It’s imperative that we start of with an ad text test but it will need to be small.  The options seem to be a 3×1 or 2×2 test matrix – 3 headlines and 1 body copy for 3 total combinations or 2 headlines mixed with 2 sets of body copy for a total of 4 combinations.  Best practices suggest that the headline copy tends to be much more effective than body copy so I’m leaning toward the 3×1 option.  With fewer combinations than the 2×2 test we’ll be able to roll into the landing page test more quickly as well.winning results with google ad words

Another short cut I’m considering is combing the ad text results across the engines.  No doubt Google, bing and Ask would have some performance nuances with regard to ad text click through rate but I’m willing to assume they’re constant for the sake of speed.  Yet another example of the digital marketer balancing speed and accuracy!
