Small business website advice, St. Clair edition

Water covers 0.7 square miles inside St. Clair, against 2.9 square miles of land. Water also means weather, insurance questions and repairs, and customers look for specialists. Photos of real jobs on the water and a plain service list beat generic beach pictures. A short, specific page does more for this audience than a clever one.

A web designer’s view of St. Clair’s businesses

The Census counted 288 establishments with employees in 2023 in ZIP code 48079, which includes St. Clair and its surroundings. Among them:

St. Clair County as a whole had 3,080 employer establishments in 2023 and another 11,337 nonemployer businesses, the one-person shops and independent contractors that often have no website at all. 30 transportation equipment manufacturers operate in St. Clair County, about eight times what the national mix would predict. In that line of work, suppliers and buyers vet capabilities; a good site gives customers capabilities, certifications and the right contact for each type of request. St. Clair’s working residents are concentrated in education, health care and social assistance (21.3%) and manufacturing (17.0%). None of them needs a complicated site; they need one that answers the customer’s first questions honestly.
