What Is the Target ROAS Strategy?

Target ROAS is a bidding strategy designed to maximize return on ad spend. It works by setting a specific return on investment goal for each paid search campaign. Here are the pros and cons of this strategy:

  • Target ROAS enables informed decisions about campaign optimization based on actual results.

‍

Cons:

  • Target ROAS can be hard to achieve when the advertising budget is limited, as competition may be fierce.
  • Target ROAS may not be the right fit for short-term campaigns, as it often takes time to reach the desired return on investment.
  • Target ROAS may not be suitable for brand awareness campaigns, since it can be difficult to directly measure the ROI of those efforts.
