Google yesterday announced its latest tool for its AdWords Advertising Platform, AdWords Campaign Experiments (ACE), which allows simultaneous split testing within AdWords.

Until recently within the AdWords system the only way to carry out a controlled split test was with before and after split testing and then comparing data once your experiment had finished which to be truly effective needs to be done over several weeks. The other disadvantage with this method of split testing is that running larger scale testing could potentially have an adverse effect on your campaign as such you may never carry out the experiment due to the risk of dips in your KPI’s such as leads.

ACE’s ability to allow simultaneous split testing, allows you to test changes such a new adverts alongside existing adverts, increased or decreased CPC or even entire campaigns and monitor them against the control for that AdGroup.

For example if you want to test a higher CPC for your best performing keyword against your current CPC , you simply set two CPC bids, a control (your current CPC) and your experimental bid. The AdWords campaign will now use both bids in a spit percentage of your choosing for example 50/50. The experiment can be set to carried out over a set time period although Google recommend a minimum of 2 weeks.

The power from this tool comes from the ability to reduce the risk in experiments which may have a large impact on a campaigns performance, such as testing new AdGroups or the addition of new high traffic driving keywords.  Risk can be reduced by adjusting the split between the control and the experiment to different percentage splits such as 80/20 (Control/Experiment), meaning for example every 800 impression your control receives, the experiment would receive just 200 limiting the risk for a fall in leads.

ACE is primarily managed from the settings tab for campaigns within AdWords, and this is where you control start/finish dates, experiment names and adjust the percentage split between test and experiment as show below:

The final gem in this tool comes from how it tracks the effect of changes. With the use of simple upward and downward indicator arrows next to the metric you are testing you can at a glance determine the effectiveness of changes and if they are in Google’s words ‘statistically significant’ irrespective of outside factors such as seasonality. Once you have determined if the change had a positive or negative effect, you can choose to ‘Accept the changes’ to apply them permanently to the campaign or ‘Delete the changes’, speeding up the process to roll out changes across the campaign.

In the below example you can see how a increase in CPC bid has result in a minor increase keyword position, as show by the experiment indicator arrow:

In a nut shell Google ACE allows a more effective and faster way to carry out split testing and more importantly an easier way to monitor the effects of your experiments.
