A slab leak click and a water heater click do not belong in one budget
Emergency intent and planned replacement intent behave differently at every stage, so they should not share a campaign, a bid or a landing page.
An emergency search converts in minutes or it never converts. A repipe search converts over days, sometimes weeks, after an estimate, a follow-up call and a conversation at a kitchen table.
Separate them into distinct campaigns with distinct budgets. Emergency work justifies aggressive bidding during the hours you can actually dispatch. Planned work justifies a longer attribution window and a landing page built to explain rather than to hurry.
Mixed together, the fast half eats the budget and the slow half looks like a failure. Both conclusions are wrong, and both are expensive.
Water heaters usually sit between the two. Give them their own ad group and their own page, because urgency varies with whether the tank is leaking or simply old.
