How do you include cross-device conversion data in bid strategies?

To include cross-device conversion data in bid strategies, you should use cross-environment conversions when computing bid adjustments. This allows the bid strategy to account for user journeys that span multiple devices, providing a more accurate picture of conversion value and optimizing bids accordingly. Manually setting device bid adjustments is a static approach that doesn't dynamically incorporate cross-device insights. Ensuring mobile bid modifiers are automatically optimized is a general best practice but doesn't specifically address the inclusion of cross-device data in the bid strategy's calculation. Creating a formula column can be useful for reporting or custom metrics, but it doesn't directly integrate cross-device conversion data into the bid strategy's optimization algorithm.
