Share of Local Voice (SoLV)
The percentage of pins where you are in the top 3. The metric clients understand first.
Share of Local Voice is the share of grid points where your business ranks in the top 3 on a geo-grid scan, the positions shown in Google's map pack.
A SoLV of 60% on a 7x7 grid means you are in the map pack at 29 of the 49 points. It is the clearest single number for a client because it maps to a real outcome: being seen without a tap on 'more places'.
Pair it with ARP
SoLV tells you how often you win. ARP tells you how badly you lose where you do not. Report both.
