Bid separately on the homeowner with drawings and the homeowner with a folder of photos
Project stage predicts close rate better than project type does, and the two buyers need different ads.
One person has plans, a designer and a start month in mind. They search for a builder who can price a defined scope. The other has a saved folder of pictures and a vague number, and they search to find out what things cost.
Both are worth having. They are not worth the same bid, the same page or the same promise. Selling a fixed scope to the first is a straightforward pitch. The second needs a process, a range and a reason to talk to you before they have decided anything.
Split them at the campaign level so budget cannot drift from the near buyer to the browser. Ad copy for the ready group should name the scope and the calendar. Copy for the researching group should offer the pricing conversation, because that is the thing they are actually shopping for.
Track them separately from the first click to the signed agreement. If the researching campaign never produces a signature, cut it. If it produces slower but larger jobs, fund it deliberately rather than by accident.
