Bid on the job that starts, not the countertop someone is pricing on a Sunday
Campaigns should be split by the job you would sell, because those jobs have wildly different values and wildly different close rates.
Run full kitchen renovation, full bathroom renovation, tub to shower conversion, and countertop or surface replacement as separate campaigns with separate budgets. Left in one campaign, the cheap high-volume clicks starve the expensive ones, and the account stops selling kitchens.
Keyword intent splits along a clean line. Remodel, renovation, gut, redesign and contractor sit on the buying side. Cost, price, average, ideas, before and after, and DIY sit on the browsing side. Browsing terms are not worthless, but they belong in a small capped campaign pointed at a guide page, never in the campaign that funds your crews.
Match types matter more in a low-volume category than most accounts admit. Broad match with a thin conversion history spends its way through neighboring categories fast. Start tighter, watch the search terms report weekly, and open up only where the data earns it.
Each campaign needs its own landing page. Sending a tub to shower searcher to a general remodeling page throws away the specificity you just paid for.
