Hello, While experimenting with the TrafficEstimatorService, I've noticed that depending on how I split up a request for multiple keywords, I get quite different results. I'm sorry if this is obvious, but I could not find any detailed documentation on this subject.
I basically tried 3 different ways to submit keywords whose CPC estimates I am interested in: first, I created a single AdGroupEstimateRequest containing all keywords. Next, I built a separate AdGroupEstimateRequest for every keyword, but still sent a single CampaignEstimateRequest. And last, I put every keyword into its own CampaignEstimateRequest and submitted multiple requests, one per keyword. I am not using any additional criteria or a limited dailyBudget. The last method described is the only one where the results closely correspond to the estimates I am getting from the Traffic Estimator Tool inside the AdWords Dashboard. The first two methods return similar results that are sometimes significantly different from the Traffic Estimator Tool. Most dazzling is the fact that for some keywords, the returned CPC estimate for a given keyword using only a single CampaignEstimateRequest is zero when it is quite large using the method with separate CampaignEstimateRequests. While I am well aware that the values returned by the TrafficEstimatorService are to be taken with a grain of salt, the differences between using the described methods are so large that there must be some fundamental distinction. Any pointers would be greatly appreciated.
