Folks, Charles is talking about a marketing principle - Recency, Frequency, and Monetary not the market company called RFG.
Charles - yes I have used similar when analysing and planning marketing. I’ve used this info to find the best performing and worst locations within my area for spend or frequency and I think we all use recency when we do our 30-90-120 days postcards.
I’ve used this basic data in ongoing monitoring of the cost effectiveness of marketing to specific neighbourhoods. In some cases I’ve stopped mailing them in others I’ve started or increased the volume of menu’s going out.
I’ve also used a data company who used my data to predict current non-customer households ‘likely to buy’ in my area to mail offers to them. All have been successful HOWEVER the cost of targeting and then posting individual mail to these people can often be way more than blanketing the whole area.
So in answer - yes I use it along with other things and it does work.
