Emergency waterproofing converts this week, a tower re-roof converts next fiscal year
The two jobs you sell run on different clocks, so they need different campaigns, separate budgets and separate definitions of success.
Leak and waterproofing searches happen under pressure. Intent is high, the click is expensive, the decision is fast. Judge that campaign weekly on calls answered and surveys booked, and staff the phone accordingly.
Capital re-roof searches behave nothing like that. A manager gathers information for a board that meets on its own schedule, and the money moves when the association's finances allow. Judging that campaign on this month's cost per lead will get it switched off long before it produces anything.
Split them at the campaign level so budgets cannot borrow from each other, and give each its own conversion action. Blended reporting on two sales cycles this different is how good spend gets cut.
Run the slow campaign at a steady, modest level rather than in bursts. Bursts miss the weeks that matter, and nobody can predict which week a roof consultant starts drafting a specification.
