Performance by device

Splits spend, clicks, conversions, CPA and ROAS by device (mobile, desktop, tablet) for the period, next to the previous period of the same length. Use when: the user asks about mobile versus desktop, or before setting device bid modifiers. Do not use when: the campaign uses Smart Bidding and the user wants to act on the split — Smart Bidding already bids per device, so the split is information, not an instruction. A device with very little spend is not evidence. Mobile usually shows a worse conversion rate on considered purchases and a better one on calls and local intent; look at the landing page before blaming the device. If you are unsure which account, campaign or period the user means, ask them — do not guess ids or dates.
