You are sitting on a market nobody can see
On auto repair shops, in one market we counted end to end, the obvious categories return 60,059 businesses. We start from 101,989, deliberately pulling in badly classified businesses that look like something else, because no classification is reliable: a genuine independent shop can be filed as a dealership, as an inspection station, or under a code that is not its own, and conversely the repair shop code is full of businesses that are not repair shops. Starting too wide is the only way to miss none of the real ones. The sorting comes after, row by row, and it surfaces the ones that are genuinely your prospects, including the ones none of your lists contain.
