Interstate 255 runs through Columbia, a city of 10,865 residents in Monroe County. For web design in Columbia, the aim is plain: be found, be understood, be contacted. Aria’s plan costs $89 a month with domain, business email and hosting, and the first monthly fee only comes after your approval.

No setup fee: you only pay the $89 monthly fee, after you approve your website.

Designing for Columbia: the facts that matter

Columbia sits 12 miles north of St. Louis, MO, and 82.0% of its workers drive to work alone. A commuter city does its shopping research at night. A contact form that works after hours and an answer the next morning beat a phone that rings during business hours only. That is the work a small business website does well: answering the first questions before anyone has to ask.

The city sits on the Mississippi River. Water also means weather, insurance and repairs, and customers look for specialists. Photos of real jobs on the water and a clear list of services beat generic beach pictures. None of that needs a big website. It takes a clear one, with the details right.

Hot months, wet months: Columbia through the year

Climate normals for 1991-2020 from Cahokia, 7.6 miles away, put the July average high at 88°F and the January average low at 22°F. About 43 inches of rain and melted snow fall in a normal year, most of it in July. Freezing nights (32°F or below) come about 97 times a year. Mild weather keeps outdoor work going most of the year: landscaping, outdoor dining and recreation stay busy for months. Seasonal updates helps: winter hours, summer specials, storm-season notices, sent by email and included in the monthly fee.

Your service area around Columbia

Nearby incorporated places: Dupo (4 miles north), East Carondelet (5.6 miles north), Bella Villa, MO (7 miles northwest), Millstadt (7 miles east), Green Park, MO (8 miles northwest) and Wilbur Park, MO (8.3 miles northwest). Monroe County’s county seat is Waterloo, 8.8 miles to the southeast. Gateway Arch National Park is a short trip away: within 12 miles. The nearest airport with an IATA code is St. Louis Downtown Airport (CPS), 8.4 miles northeast. A service area page that lists the towns you cover, from Columbia to Dupo and Bella Villa, answers the first question many customers have: do you come to me?

The Columbia business count, sector by sector

ZIP code 62236, which covers Columbia and the area around it, had 425 business establishments with employees in 2023. Here is part of that mix, with what each website should show:

  • CPA firms: 7. Their website should show services for individuals and businesses, the team and a contact form for new clients.
  • Golf courses and country clubs: 3. Their website should show the course, rates you choose to publish, events and a contact form.
  • Landscaping companies: 10. Their website should show seasonal service menus, the neighborhoods you cover and photos of finished yards.
  • Chiropractic offices: 5. Their website should show what a first visit looks like, your hours, the insurance you accept and a way to request an appointment.
  • Full-service restaurants: 17. Their website should show the menu, the dining room, private-event information and the hours, kept current by email.

County-wide, Monroe County counts 875 businesses with employees and 2,561 self-employed or nonemployer businesses (2023). Compared with the U.S. as a whole, Monroe County leans toward recreation and amusement businesses (22 establishments, 2.4 times the national share). In that business, visitors and locals check hours, prices and what to expect, and the website should show activities, prices, hours by season and how to book a group by email. Nursing and residential care facilities are also overrepresented (19, twice the national share). The jobs Columbia residents hold are mostly in education, health care and social assistance (25.4%) and retail trade (11.6%). Every one of them is a search away from a customer in Columbia.

What Illinois asks of a business with a website

Before your website goes live, it helps to have the basics of the business in order.

  • Check with both Monroe County and the City of Columbia about local business tax receipts before opening. Official source
  • If you send marketing email from your new business address, the CAN-SPAM rules (16 CFR Part 316) apply, including an easy way for people to opt out. 16 CFR Part 316
  • Illinois taxes general merchandise at a 6.25% state Retailers’ Occupation Tax rate, with a preferential 1% rate on qualifying drugs and medical appliances; municipalities and counties add local rates. Illinois Department of Revenue

Each business is different; this is general information, not legal advice.
