Bid by borough, because a Manhattan click and a Staten Island click are different products
A single campaign covering the metro averages away the only distinction that matters to your margins.
Prices per click, competition and job size all change across the city. Manhattan attracts the heaviest bidding and often the largest projects. Queens and the outer boroughs are cheaper to reach, and the work skews toward two family houses and smaller co-ops. Nassau and Westchester behave like separate markets entirely.
Split them so the numbers stay readable. Separate campaigns, or at minimum separate ad groups with their own budgets, let you see that a Bay Ridge lead cost a fraction of a Chelsea lead and closed at a similar rate. Mixed together, that never surfaces.
Target the areas your crews can serve, and be honest about what serving means without a truck that can park. If a job in Riverdale means an hour each way plus a parking problem for a two-person crew, price that into whether you bid there at all.
Exclude what you will not travel to rather than hoping the platform reads your mind. Location targeting quietly includes people who merely show interest in an area, so check the setting that limits delivery to people actually in the places you chose.
