Why Maps visibility matters more here than for smaller-ticket trades
Map Pack visibility accounts for roughly half of all inbound calls for local service businesses generally, and for a generator dealer specifically, that's half a customer base evaluating a purchase in the thousands of dollars, not a small repair call. Losing map pack visibility here has a proportionally larger revenue impact than it would for a lower-ticket trade.
Active profile management, not a one-time setup
Google rewards profiles that stay active: posting 2 to 3 times a week (service highlights, recent installations, community involvement) signals an operating business rather than a dormant listing. This is separate from, and additive to, the underlying category and description accuracy, which should reflect the specific brands and system types installed rather than a generic "electrician" or "contractor" label.
Recency beats raw review count
A business with 50 reviews earned over the past year will generally outrank one sitting on 200 reviews that are all three years old. For a business selling a considered, high-ticket purchase, recent reviews also do more persuasive work for the customer than an old, static number, since they're often researching a purchase they'll only make once every decade or two.
