The map pack is drawn around your shop, and it stops at the shoreline
Local pack results are weighted heavily by distance between the searcher and your verified address, which means a Hillsborough shop rarely surfaces for someone standing in Clearwater.
A single verified location in Brandon puts you in contention for Brandon, Riverview and parts of Temple Terrace. It does not put you in Pinellas Park, and no amount of on-page work changes that. Distance is doing most of the sorting.
The usual reaction is to want more listings. Google generally requires a staffed location with real signage for each one, and virtual offices get suspended. Rules change, so it is worth confirming current guidance before you spend anything, but the safe read has been stable for years: one listing per place where a person actually works.
What the pack gives you is tonight's no-cool call within a few miles. What it will not give you is the planned replacement three weeks out on the far side of the water. Organic pages carry that work, and they carry it at distance.
So answer the operational question before the marketing one. Which addresses can you reach at four on a weekday without wrecking the rest of the board? Everything downstream depends on that answer being honest.
