Review generation and reputation for a detailing business
Reviews are the cheapest advantage in this trade and almost nobody works them. Median review count across the benchmark set is 24, 37.2% of listings sit under ten, and 14.1% have none at all. Getting to sixty honest reviews puts you ahead of most of your town.
The moment to ask is at handover, with the customer standing in front of a car that looks better than they expected. Not by email the next day. "If you are happy with it, a Google review helps me more than anything else. I will text you the link right now." Then send it before they drive off.
A shop doing 60 cars a month that asks every single time adds fifteen to twenty five reviews a month. Ask nobody and you add one.
Two weeks of asking properly should produce eight to fifteen new reviews and a reply on every old one, including the two you have been avoiding.
