Frequently asked questions
What is a good CTR?
Search ads often reach 3–6%; display and social ads typically sit well below 1%. Compare against your own past campaigns first.
ROAS or ROI?
ROAS measures revenue per unit of ad spend; ROI subtracts all costs. A ROAS of 3 can still lose money on thin margins.
