Due to a change in budgeting, you need to quickly adjust your entire campaign to automatically increase bids on mobile devices by 20 percent. How can you accomplish this?

Device bid adjustments allow you to set a percentage increase or decrease for bids on specific device types, such as mobile, tablet, or desktop. To increase bids on mobile devices by 20 percent, you would apply a +20% device bid adjustment at the campaign level. This method directly addresses the need to automatically modify bids for mobile devices across the entire campaign. Bid strategy opportunities suggest potential improvements but don't directly implement bid changes. Custom Floodlight variables are used for tracking conversions, not for bid management. Manual CPC bidding requires individual bid changes, which is not an automatic adjustment for the entire campaign.
