What Columbus, OH is underserved in
The biggest opening in Columbus right now is bathroom remodeling: about 2,490 searches a month across Franklin County, and local companies pay $40.13 for each click. The three businesses at the top of Google Maps for it have a median of 98 reviews, so expect a longer climb to the top three. For dock builder, no local company's own website makes Google's top results; only directories and national sites do. Too few searches here to build on: deck builder, excavation contractor, seawall repair, sprinkler repair and water softener installation. Columbus 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.
