How do device bid adjustments affect campaign performance?

• A. You can bid higher or lower by device (mobile, desktop, tablet) to reflect performance differences and user behavior.
• B. They cannot be used for devices.
• C. They only apply to desktop devices.
• D. They automatically set bids for all devices.

Answer: (B)

Device bid adjustments let you tailor how much you bid for clicks on each device type—mobile, desktop, and tablet—based on how well each device performs and how users behave on them. If mobile tends to drive more conversions or lower CPA, you can raise your mobile bid to win more mobile auctions; if tablet underperforms, you can lower its bid to control cost. This tuning directly affects the CPC you’re willing to pay for clicks on each device and helps improve overall campaign performance by aligning spend with device-specific value. They apply to individual devices, aren’t limited to desktop, aren’t automatic across all devices, and aren’t a single bid for every device.
