AdDistribution Element
If you remove "Content" from the AdDistribution element of an existing ad group, adCenter preserves the ContentMatchBid value for all keywords in the ad group. If you later add the "Content" distribution type back to the same ad group, the keywords have the previous value for the ContentMatchBid element.
CashBackInfo Element
This API element can be used only by members of the cashback rebate program.
If the CashBackInfo element is null, the campaign is not enabled for the cashback rebate program. Otherwise, this element contains a CashBackInfo object that contains the cashback rebate program information.
For more information about the cashback rebate program, see Cashback Rebate Program.
ContentMatchBid Element
If you set a value for the ContentMatchBid element and your ad group doesn't target the United States distribution region, your service operation calls return successfully. However, the ContentMatchBid value is ignored. (To display content ads with the Microsoft adCenter API, your ad group must target the United States distribution region.)
Only search ad values are used by adCenter if your ad group doesn't target the United States distribution region.
EndDate Element
When updating an ad group, to set no end date for the ad group, set the EndDate element to a date equal to or later than January 2, 2050.
When an ad group is added and if no end date is specified, the ad group does not have an end date.
NegativeKeywords Element
The NegativeKeywords element must contain an empty array if no negative keywords are specified. Negative keywords can be specified only for a keyword that has a broad or phrase match type. For more information about negative keywords, see Negative Keywords.
The maximum length of a single string in this array is 100 characters. The maximum combined length for all strings in this array is 1,022 characters.
NegativeSiteUrls Element
The NegativeSiteUrls element contains the set of URLs that your content ads won't get displayed on. For example, if you add "http://www.contoso.com" to the set of negative site URLs, your content ads are never displayed on this site. Negative site URLs only apply to content ads.
PricingModel Element
The PricingModel element is used only when an ad group is created. This value cannot be changed after the ad group is created.
This element is required when an ad group is created.
StartDate Element
When adding an ad group, if the StartDate element is null, the current date on the server is used as the start date.
Status Element
The Status element is read-only. The ad group status can be changed only by using either the PauseAdGroups or the ResumeAdGroups service operation.
