What does ARP & ATRP mean?

In your Scan Reports, ARP = Average Rank Position and ATRP = Average Total Rank Position.

The difference is that the ARP is an average of only the pins that actually have a result (position 20 or less), while ATRP averages all the pins, even when a business is not found (20+).

This difference helps you compare if a business is ranking well across a wide area, or if they are ranking well in only a small area within the search grid.
