A budget bid strategy lets you automatically optimize spend toward the key metrics you have chosen for a plan. For example, if your key metric is clicks, then your budget bid strategy automatically optimizes spend to get the most clicks at the lowest average cost per click given the amount you want to spend over the date range of the plan. If your key metric is Target CPA (Cost-per-action), then the goal is to maximize conversions. If the goal is revenue, your key metric is Target ROAS (return on ad spend).
To achieve your key metrics within the parameters of your plan, a budget bid strategy can make changes to individual campaign budgets, bids, and bid adjustments. As such, you see variations in daily or weekly spend as your plan progresses.
A budget bid strategy needs at least three weeks of performance data for each campaign in the group in order to optimize plan performance. (If you start a new campaign for which there is no historical performance data, manage the campaign manually until you have at least three weeks of data.)
