What is the Groundwork market score?
The Groundwork market score runs from 0 to 100 and compares a market with others of its kind for one business type: states with states, metro areas with metro areas, small-town markets and counties with their own. It weighs household spending per competitor (35%), households per business with payroll (25%), population growth (20%) and spending power (20%), each ranked against those peers. A higher score means that, taken together, the market has more household spending and more households for each business already there, faster population growth and more spending per household than similar markets. It describes a market, not any one site or deal. Iowa scores 38 for HVAC and plumbing companies (lower middle), #37 of the 50 states and DC.
How can I see the market around a specific site?
Run a Groundwork site report on an address in Iowa. It maps the HVAC and plumbing companies on map listings near the site and sizes the households and spending within the distance you choose. New accounts get 10 actions over 3 days, no card.
