Yes, you can optimize to one or more goals, such as online and in-store conversions, from a single Performance Max campaign. As a best practice, track the value for all your conversion goals. By doing this, Performance Max will maximize conversion value for your budget. If your goals share the same budget and geography, you can target multiple goals from a single Performance Max campaign. If you have a separate budget that cannot be combined with other goals, you can create separate Performance Max campaigns that optimize for different goals.
