BiddingScheme Data Object - Campaign Management
Defines the base object of a bidding scheme for how you want to manage your bids. A bidding scheme is known as a bid strategy type in the Microsoft Advertising web application.
Do not try to instantiate a BiddingScheme. You can create one or more following objects that derive from it.
If the campaign bid strategy type is set to MaxClicks, MaxConversions, or TargetCpa, the behavior of existing features will change unless you set an individual ad group's or keyword's bid strategy to ManualCpc. For more details, see Budget and Bid Strategies.
- You can continue to set the ad group and keyword bids; however they will not be used by Microsoft Advertising.
- Microsoft Advertising will periodically change your stored ad group or keyword bid settings. You can continue to set new bids, however Microsoft Advertising may change them at any time using this bid strategy type.
- You can continue to set bid adjustments e.g. for age, gender, or location; however, the multiplier will inform rather than directly modify or override the automated bid. For auto bidding the multiplier is used as a weighted percentage to inform Microsoft Advertising about how much you value the criterion relative to other criteria. For example, a -50% bid multiplier for a mobile device criterion with the Max Conversions bid strategy to indicate that you value conversions from mobile traffic half as much as other device types. The same bid multiplier with the Max Clicks bid strategy would indicate that you value clicks on mobile half as much as other device types. The valid range of values that you can use to inform auto bidding is -100.00 through 30.00.
- Even if the AdRotation is set to RotateAdsEvenly, it will be ignored as these bid strategies prioritize better-performing ads.
Also note that you must have conversion tracking (via Universal Event Tracking tag and a conversion goal) set up for the MaxConversions and TargetCpa bid strategy types to work. To set the MaxConversions or TargetCpa bid strategy types, the campaign must have at least 15 conversions in the last 30 days. If you try to add or update a campaign to use one of these strategy types, the requested operation will fail if there is not enough conversion history. If an active campaign uses one of these bid strategy types, and then ceases to meet the minimum conversion history requirement at any time, Microsoft Advertising will stop auto bidding but will continue to use the DailyBudgetStandard budget type. For a new campaign we recommend that you start with EnhancedCpc and then when the campaign has enough conversion history, you can update it to use either the MaxConversions or TargetCpa bid strategy.
You can set your campaign's bid strategy to EnhancedCpc, MaxClicks, MaxConversions, or TargetCpa and then, at any time, set an individual ad group's or keyword's bid strategy to ManualCpc.

|Type||The type of bidding scheme that is set for this campaign, ad group, or keyword.
For more information about bidding scheme types, see the Remarks.
For Java and the .NET languages, do not set the Type element because the value is determined by the object instance.
If you generate the SOAP manually, use the type attribute of the
<BiddingScheme> node as shown in the following example.
<ns1:BiddingScheme xsi:type="ns1:ManualCpcBiddingScheme"> <ns1:Type xsi:nil="true"/> </ns1:BiddingScheme>
