Meta spreads your budget across whoever its system can find, so in a metro this size the audience does most of the work.
Detroit's map has hard edges: older brick homes and bungalows in the city and inner ring, Macomb's Warren and Sterling Heights, Oakland County's larger suburban homes, and Ann Arbor's university-driven rental market. Each responds to different offers.
A homeowner in Royal Oak might see a basement waterproofing inspection, a landlord in Dearborn a rental review, a facility manager in Troy a walkthrough. Winter drives furnace and pipe messages, spring drives storm and pest messages, and summer drives cooling.
Ads carry only the proof you hold, whether that is a Michigan broker license or a LARA contractor license, and the license itself stays with you.
