ZIP code 63121, which covers Greendale and the area around it, had 315 business establishments with employees in 2023. A few examples from the same count:

  • Home health care agencies, 20 in the count. What works online: the services and areas you cover, how families start care and a contact form that reaches the office.
  • Quick-service restaurants, 14 in the count. What works online: today’s hours, the menu and photos that look like what customers get.
  • Cleaning services, 6 in the count. What works online: what is included in each type of cleaning, the towns you serve and a contact form.
  • Child care centers, 10 in the count. What works online: ages served, hours, tuition or fees and how to schedule a tour.
  • Tax preparation offices, 3 in the count. What works online: your services, what documents to bring, seasonal hours and a contact form.

St. Louis County as a whole had 29,717 employer establishments in 2023 and another 88,357 nonemployer businesses, the one-person shops and independent contractors that often have no website at all. St. Louis County has 2.2 times the national share of social assistance and child care providers: 1,554 of them in the 2023 count. In that line of work, families look for programs and eligibility, so the website should show programs, eligibility, hours and how to apply or enroll. Most of these businesses are small, and the website does the job a front desk would do in a bigger company.
