Questions
What is a good ROAS?
It depends on your margins. A campaign breaks even when ROAS equals 1 divided by your gross margin. The ROAS calculator works this out for you.
Should UTM tags be lowercase?
Yes. Analytics tools treat "Facebook" and "facebook" as different sources, so a consistent lowercase convention keeps reports clean.
