What Chicago, IL is underserved in
The biggest opening in Chicago right now is ac repair: about 15,760 searches a month across Cook County, and local companies pay $32.13 for each click. The three businesses at the top of Google Maps for it have a median of 207 reviews, so expect a longer climb to the top three. Too few searches here to build on: impact windows, mobile home repair and screen enclosure repair. Chicago is one of the biggest US cities, so scores here run high on sheer demand. Established companies spend heavily on ads and reviews, and the map pack is much harder to crack than in a mid-size town; a suburb or a single neighborhood is often the easier start. Big cities are left out of our national rankings for that reason.
