Access to manage AdWords Campaign Experiments (ACE) has been introduced through the ExperimentService as part of the v201008 version of the AdWords API. Now you are able to configure split test experiments for a campaign through the API. A split test experiment lets you more precisely measure the impact of changes to keywords, bids, ad groups, and placements before you apply them to all auctions. This reduces guesswork and lowers the potential risk. For common usage scenarios and more details, check out AdWords Help Center.
Lets get hands on with the code and see how to use ACE via the AdWords API. The following code snippets are available as part of the Perl client library.
