Backyard work and building work cannot share one campaign budget
Two buyers with different click rates and different deal sizes inside one budget means the cheaper clicks always win, regardless of which pipeline is worth more.
Separate campaigns by job family: new residential construction, residential remodel and resurface, and commercial or association deck and pool work. Each gets its own landing page, its own budget cap and its own definition of a good outcome.
Residential terms attract far more clicks. If commercial keywords sit in the same campaign, the algorithm will quite sensibly spend where the volume is, and you will conclude that commercial paid search does not work when you never actually bought it.
Separate budgets also give you a lever. When the residential backlog stretches past what a customer will tolerate, you can throttle that campaign and push money toward the pipeline with a longer runway, without rebuilding anything.
Landing pages must match. A property manager who lands on a page of backyard photographs bounces, and the click is gone. Send them to a page about elevated and commercial work, with credentials visible and a form that asks about the building.
