Emergency demand ignores the auction
During a surge, paid click costs can rise sharply as every competitor bids simultaneously. Branded searches and direct calls arrive at the same cost they always did, which is nothing.
The share of surge demand that reaches you without an auction is almost entirely determined by how well known you were beforehand.
Trust matters more after a disaster
Storm events attract out-of-town operators, and homeowners know it. Suspicion of unfamiliar contractors runs high in exactly the period when demand peaks.
An established local name with a visible history is the safe choice in that moment, which is worth considerably more than a lower price.
Language doubles the reachable audience
A large portion of Houston households speak Spanish at home, and many competitors never build presence there at all.
Recognition inside that audience is unusually cheap to establish precisely because so few businesses are competing for it, and it holds through surge periods the same way any other recognition does.
