The audience refreshes itself
In a static market, reputation is harvested slowly from a fixed population. Charlotte hands you a fresh set of undecided households every month, which means the same reputation gets monetized repeatedly.
That is a compounding asset in a way it simply is not elsewhere, and it is why local standing is worth building here even though it takes quarters rather than weeks.
First choices are sticky
A provider chosen during someone's first months in a new city tends to be kept for years, because switching costs attention that a settling household does not have to spare.
So the value of winning that moment is not one job. It is the lifetime of a customer who never seriously shops again.
Recommendation beats ranking at this stage
A newcomer with no local knowledge trusts a person over a search result, because they have no way to evaluate the result and every reason to trust the neighbor.
Advertising can reach them, but the recommendation is what converts them, and only presence over time produces recommendations.
