Optimize spend by making adjustments to your campaigns in a plan. You can change individual budgets, bids, and bid adjustments. Or, set up a budget bid strategy (also referred to as a budget strategy) to automatically set and adjust spend.
The primary focus of a budget strategy is to spend the amount specified in a plan. This means that you can anticipate variations in daily or weekly spend as the budget bid strategy makes changes to optimize how the entire budget is spent.
New campaigns with no previous performance data will not be able to have budgets properly set after placed in a budget bid strategy. New campaigns will need to first actively run on another bid strategy to gain the necessary performance data before being added to a budget bid strategy.
Similar to a Search Ads 360 bid strategy
Search Ads 360 budget strategies are very similar to Search Ads 360 bid strategies. Both use performance history to set bid adjustments. Both can set bids for biddable items. Both can include some limits. As with a bid strategy, a manually set bid overrides a budget strategy for 24 hours.
Budget bid strategy campaign budgets and bids can be overridden for 24 hours
Manually set campaign budgets and manually set bids for biddable items override a budget bid strategy for 24 hours.
A budget can be overridden only in the Search Ads 360 user interface. For example, if you set a different daily budget for a campaign using the Google Ads user interface, the change is ignored.
Note that we don't recommend manually setting a budget or bids when a budget bid strategy is managing spend in a plan.
The primary differences are that a budget strategy optimizes a budget by allocating spend and changing bids, and can only be configured as part of a plan.
A Search Ads 360 bid strategy doesn’t manage budgets and sets default bids.
Here’s a list of the similarities and differences.
| Feature | Budget bid strategy | Bid strategy |
|---|---|---|
| Included in a plan |
Yes A budget strategy is an optionally enabled component of a plan that you can turn on or off before or during a plan. One budget bid strategy is created for a campaign, even if each plan for the campaign includes a different goal and different budget strategy settings. A budget strategy is automatically enabled in a plan only if it was used in the previous plan. |
No Search Ads 360 bid strategies stand alone. You can set up a Search Ads 360 bid strategy and apply it to individual campaigns. (You can also create a bid strategy and then not use it. That is, you can create a bid strategy and not apply it to a campaign.)

How campaign Bidding and Planning options work with budget strategies
Campaign budgets can be managed by using any of the following methods. Some methods work with a budget strategy, while others are replaced by a budget strategy. For example, manually managed budgets can be automatically managed by a budget bid strategy. A Search Ads 360 bid strategy can be replaced by a budget strategy.
- Manual campaign budget. The campaign daily budget is specified in campaign settings. Manually set campaign budgets can be switched to an automatically adjusted budget if a budget strategy is applied.
- Shared budget (automated Bidding and Planning type in Google Ads and Microsoft Advertising). The advertising platform automatically adjusts how your budget is spent across its campaigns to optimize performance. Note that a budget bid strategy that doesn't have Google Ads auction-time bidding enabled can't manage shared budgets. To allow a budget bid strategy without Google Ads auction-time bidding to manage the budgets, the campaigns must be removed from the shared budget.
Important details about budget bid strategies
- For optimal performance, enable a budget bid strategy when you create a plan or near the beginning of a plan.
- A budget strategy will manage campaign budgets and bids for keywords and other biddable items for every campaign to optimize spend. In the budget bid strategy settings, the "Campaign daily budgets" and "Keywords and other biddable items" checkboxes are selected and unavailable to indicate this requirement.
- A budget strategy applies to all items in the campaign. That is, if you enable a budget bid strategy for multiple campaigns, the budget bid strategy removes any Search Ads 360 bid strategies from the campaigns, ad groups, keywords, and product groups and manages the budgets and bids for all biddable items in the campaigns.
- For your first plan for a campaign, the budget bid strategy needs at least 3 weeks of data to analyze. When there's a sufficient amount of data, the budget bid strategy requires a week to analyze the data. A budget strategy may also enter learning mode if the following types of changes occur:
- Transition to a new plan.
- Campaigns are added or removed.
- Budget changes by more than 30% in a new plan. Or, changes to the target spend in a running plan.
- A budget bid strategy uses the most recent budget, bids, and bid adjustments before making changes.
- Although a budget bid strategy can't adjust the budgets of Google Ads and Microsoft Advertising campaigns that use a shared budget, the strategy does set bids for campaigns in shared budgets. For a budget bid strategy with Google Ads auction-time bidding enabled, Google Ads campaigns can be in shared budgets. Search Ads 360 automatically creates a shared budget for the active Google Ads campaigns, except for Google Ads Performance Max. Search Ads 360 also doesn't create a shared budget for Microsoft Advertising, Yahoo! Japan Ads, or Baidu campaigns.
- If a budget strategy is managing spend, only specify custom allocations for major sales events for holidays such as Singles Day. Don't set a custom allocation for the last week of a plan when a budget bid strategy is managing spend.
