Aggregating Data

This page has been deprecated and the content will not be refreshed as of February 2013.

Instead please see Ad Intelligence Service Reference, Researching and Pricing Keywords, or Bing Ads API Overview.

For operations that provide historical performance, such as GetHistoricalKeywordPerformanceByDevice, you can request data for multiple publisher countries. If you specify multiple countries, the data is aggregated across the countries. If you set PublisherCountries to NULL, the data is aggregated across all countries that support the specified language.

For example, if you set Language to English and PublisherCountries to NULL, the GetHistoricalKeywordPerformanceByDevice operation will set the AverageBid value to the maximum bid specified across all countries that support English. However, the other KPI values, such as Clicks, will be set to the sum of those values across all the countries that support English.

Likewise, if you set Language to English and PublisherCountries to a list of countries, the GetHistoricalKeywordPerformanceByDevice operation will set the AverageBid value to the maximum bid specified across the countries and set the other KPI values, such as Clicks, to the sum of those values across the specified countries.

If your goal is to compete successfully in a country, you should specify only that country. Specifying a single country will provide more appropriate bid information for that country. If you specify multiple countries, the bid will be the highest bid across all countries, which could result in overbidding in some countries. However, if your goal is to get the historical cost of doing business in multiple countries in order to plan your budget, you should specify all the countries that your campaign will target.

For operations that provide estimates, such as GetEstimatedBidByKeywords, you can request data for multiple publisher countries but the behavior is different in the case where PublisherCountries is NULL. In this case, instead of aggregating the data across all countries, the response calculates results using data from the country with the most impressions.

For operations that suggest keywords, such as SuggestKeywordsFromExistingKeywords, the behavior is the same as that of operations that provide historical performance.
