The analysis itself based on three characteristics:
- Recency - how long ago the last purchase was made
- Frequency - how often customer purchases
- Monetary - customers average bill value
Referring to RFM-analysis settings here everything depends on what recency, frequency or monetary is concerned to be high or low in your business. You set necessary value to each of the segments and send widget to re-count. RFM-analysis collects data all over the base for the whole time and doesn't depend on the time limits set in your global analytics.
