MaxConversionsBiddingScheme Data Object - Campaign Management

Defines an object that represents the maximum conversions bid strategy type.


The MaxConversions bid strategy is available only for Search campaigns.

The MaxConversions bid strategy is available only to advertisers targeting the following countries: Australia, Canada, France, Germany, United Kingdom, and United States.

With the MaxConversions bid strategy, you don't need to set ad group or keyword bids. Microsoft Advertising automatically sets your bids in real time to get as many conversions as possible within your budget.

Microsoft Advertising will always respect your overall budget limit, but if you want greater control over your bids while using Maximize Conversions, you can also set a maximum CPC (cost per click). This is an optional limit you can set to make sure that Microsoft Advertising never pays more than a certain amount for each individual click.

You need to have conversion tracking (a UET tag and a conversion goal) set up and have had at least 15 conversions in the last 30 days in order to use the Maximize Conversions bid strategy. If your campaign falls below 15 conversions over any 30-day period, Maximize Conversions will stop optimizing your bids. If this happens with regularity, we recommend switching to a different bid strategy.


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.
