Snow removal contractors and Logan Square apartment hunters will spend your budget by Thursday
Broad commercial phrases in this market pull renters, job seekers and vendors looking for work, so the exclusion list matters more than the bid.
Commercial property Chicago and commercial building Chicago are not tenant phrases. They pull people hunting apartments in Logan Square and Lakeview, contractors looking for janitorial and plowing contracts, and students writing papers.
Build the negative list before anything goes live: rent, apartment, studio, jobs, hiring, salary, cleaning, plowing, course, license, and the names of the portals your prospects are probably on.
Read the search terms report weekly for the first month, then monthly. Fall adds its own contamination, because vendors and property managers start searching snow and ice contracts well before the first storm and every one of those queries looks commercial to a broad match.
Exact and phrase match do most of the work in a market this thin. Broad match with an automated bid strategy and a short negative list is the fastest way to spend a quarter's budget on nothing.
