In a restaurant town, the word kitchen buys you commercial build-out clicks
Your most expensive waste is traffic from a completely different industry that happens to share your vocabulary.
The city runs on restaurants, and Google does not know you only work in houses. Searches for hood systems, walk in coolers, food truck fit outs, equipment repair and commercial build outs will find a broad kitchen campaign and spend residential money on them.
Build the exclusion list before launch rather than after. Commercial, restaurant, hood, cooler, equipment, supply, wholesale, repair, jobs, salary, apprentice, DIY, refacing, cabinet doors only, and every appliance brand you do not install.
Then read the search terms report weekly for the first two months. Nothing else you do in the account will return as much per hour. After that, monthly is usually enough as long as somebody actually does it.
Match type does more of this work than the negative list ever will. Broad match paired with an automated bid strategy is very good at finding the commercial traffic on its own, and it will do so with your budget.
