This just out from Google:
We’ve just completed a new analysis on the performance of campaigns which have adopted Conversion Optimizer. We found that on average, these campaigns achieved a 21% increase in conversions while at the same time decreasing their CPA by 14%.
The analysis compares the performance of Conversion Optimizer campaigns with a control set of campaigns and represents the average impact of Conversion Optimizer. The actual impact will vary from campaign to campaign (and a small number of advertisers could conceivably perform better without Conversion Optimizer).
If you would like to learn more about Conversion Optimizer, the results we’ve seen, and how it can help you get more conversions and lower CPA, join us for one of the three webinars we are hosting March 18-19th.
