Does Google Ads work for dumpster rental companies?
Yes. Dumpster rental is a search-driven purchase: a homeowner or contractor needs a container by a certain date, searches "dumpster rental" plus their town, and books with one of the first few companies that show a price and availability. There is little brand loyalty, so being visible at that moment is most of the battle.
The margin on a single rental is modest compared with a furnace or a roof. A dumpster account has to keep cost per booking low, and it has little room for wasted clicks.
