Re: Changing bids for individual keywords , using experment compare the results and if necessary to remove unsuccessful experments

[Sarah Riddell]

Hi Josh,

Thanks for reply,

This is the code works for me , let me know am i doing anything wrong?

Working Code:

function AddExperimentExample(AdWordsUser $user, $campaignId, $adGroupId) {
    // Get the services, which loads the required classes.
    $experimentService = $user->GetService('ExperimentService', 
ADWORDS_VERSION);
    $adGroupService = $user->GetService('AdGroupService', ADWORDS_VERSION);
    $adGroupCriterionService =
        $user->GetService('AdGroupCriterionService', ADWORDS_VERSION);

    // Create experiment.
    $experiment = new Experiment();
    $experiment->campaignId = $campaignId;
    $experiment->name = 'ca_experiment';
    $experiment->queryPercentage = 10;

    // Set additional settings (optional).
    $experiment->startDateTime = date('Ymd His', strtotime('+1 day'));
    $experiment->endDateTime = date('Ymd His', strtotime('+1 month'));

    // Create operation.
    $experimentOperation = new ExperimentOperation();
    $experimentOperation->operand = $experiment;
    $experimentOperation->operator = 'ADD';

    $experimentOperations = array($experimentOperation);

    // Make the mutate request.
    $result = $experimentService->mutate($experimentOperations);

    // Display result.
    $experiment = $result->value[0];
    printf ("Experiment with name '%s' and ID '%.0f' was added.\n",
        $experiment->name, $experiment->id);

    // Create ad group bid multipliers to be used in the experiment.
    $adGroupBidMultipliers = new ManualCPCAdGroupExperimentBidMultipliers();
    $adGroupBidMultipliers->maxCpcMultiplier = new BidMultiplier(2);

    // Create ad group experiment data.
    $adGroupExperimentData = new AdGroupExperimentData();
    $adGroupExperimentData->experimentId = $experiment->id;
    $adGroupExperimentData->experimentDeltaStatus = 'MODIFIED';
    $adGroupExperimentData->experimentBidMultipliers = 
$adGroupBidMultipliers;



    // Create updated ad group.
    $adGroup = new AdGroup();
    $adGroup->id = $adGroupId;
    $adGroup->experimentData = $adGroupExperimentData;

    // Create operation.
    $adGroupOperation = new AdGroupOperation();
    $adGroupOperation->operand = $adGroup;
    $adGroupOperation->operator = 'SET';

    $adGroupOperations = array($adGroupOperation);

    // Make the mutate request.
    $result = $adGroupService->mutate($adGroupOperations);

    // Display result.
    $adGroup = $result->value[0];
    printf ("Ad group with name '%s' and ID '%.0f' was updated in the "
        . "experiment.\n", $adGroup->name, $adGroup->id);


    // Create ad group bid multipliers to be used in the experiment.
    $adGroupBidMultipliers = new 
ManualCPCAdGroupCriterionExperimentBidMultiplier();
    $adGroupBidMultipliers->maxCpcMultiplier = new BidMultiplier(4);

    // Create experiment data for a new experiment-only keyword.
    $adGroupCriterionExperimentData =
        new BiddableAdGroupCriterionExperimentData();
    $adGroupCriterionExperimentData->experimentId = $experiment->id;
    $adGroupCriterionExperimentData->experimentDeltaStatus = 'MODIFIED';
    
$adGroupCriterionExperimentData->experimentBidMultiplier=$adGroupBidMultipliers;

    // Create keyword.
    $keyword = new Keyword('cloud', 'BROAD');

    // Create ad group criterion.
    $adGroupCriterion = new BiddableAdGroupCriterion();
    $adGroupCriterion->adGroupId = $adGroupId;
    $adGroupCriterion->criterion = $keyword;
    $adGroupCriterion->experimentData = $adGroupCriterionExperimentData;


    // Create operation.
    $adGroupCriterionOperation = new AdGroupCriterionOperation();
    $adGroupCriterionOperation->operand = $adGroupCriterion;
    $adGroupCriterionOperation->operator = 'ADD';

    $adGroupCriterionOperations = array($adGroupCriterionOperation);

    // Make the mutate request.
    $result = $adGroupCriterionService->mutate($adGroupCriterionOperations);

    // Display result.
    $adGroupCriterion = $result->value[0];
    printf("Keyword with text '%s', match type '%s', and ID '%s' was added 
to "
        . "the experiment.\n",
        $adGroupCriterion->criterion->text,
        $adGroupCriterion->criterion->matchType,
        $adGroupCriterion->criterion->id);
}
