AdWords advertisers have long been able to split-test two or more ads against each other. Split-testing other variables — like bid amounts, match types and keyword variations — hasn’t been as easy … until recently. Last year, Google introduced ACE, an acronym for AdWords Campaign Experiments, which makes other types of split-testing possible.
Now you can test any number of variables against your control. Google will alternately serve the control and test variations, calculate the results, and let you know whether you have enough responses to be statistically significant.
The beauty of ACE is that it eliminates the need for testing variables in succession – say, Bid Amount A in Week 1, and Bid Amount B in Week 2. It’s much more scientific, because simultaneous testing removes week-to-week and month-to-month influences like weather and holidays.
