Question
What does the "Estimated relative expenditure per month" chart mean?
Answer
The "Estimated relative spend per month" chart shows ad spend relative to previous months. The value 100 means that the maximum amount of money was spent on ads on this date.
If the value is less than 100, a correspondingly lower percentage of expenditure was made.
