Similar to the second step, you have a choice of doing this the simple way or the sophisticated way. However, it is very important that you do not combine the testing of step 2 and 3. Otherwise, you’ll get mixed results that won’t be genuine.
The simple way is to position ads in the highest value spots shown below:
You can move the ads around using educated guesses every month to test different ad spots and sizes.
The sophisticated way involves using multivariate testing for your ad placement. This would test for the optimal combination of ad size, and ad placement. The implementation of this sophisticated test isn’t easy and would require a decent amount of programmer resources. Again, we would recommend Google Website Optimizer for such a test. Although this method does suck up the most resources, the ROI would be higher for this method of testing.
