The Potosi your customers live in

Potosi has been around since 1826; that is more than two centuries of local history. History cuts both ways for a small business: the old names are known, and the new ones have to explain themselves more clearly. If the business has served Potosi for a while, say so plainly and show it with photos of the shop over the years.

Seasons in Potosi, and what they do to your website

Potosi weather, in normals: July highs around 86°F, January lows around 21°F, measured at Potosi, 4.5 miles away (1991-2020). Precipitation totals about 45 inches a year, with May the wettest month. Freezing nights (32°F or below) come about 103 times a year. Winter changes what people need: snow removal, heating and ice-dam repairs in the cold months, yard work and construction once it thaws. Give seasonal work its own page, so customers find them when they need them.

A web designer’s view of Potosi’s businesses

ZIP code 63664, which covers Potosi and the area around it, had 207 business establishments with employees in 2023. A sample of that count, and what each kind of business needs online:

  • Child care centers, 5 in the count. What works online: ages served, hours, tuition or fees and how to schedule a tour.
  • Quick-service restaurants, 8 in the count. What works online: the menu with prices, hours and the closest cross streets.
  • Chiropractic offices, 3 in the count. What works online: what a first visit looks like, your hours, the insurance you accept and a way to request an appointment.
  • Local trucking companies, 3 in the count. What works online: the freight you haul, the areas you cover and a contact form for shippers.
  • Custom home builders, 3 in the count. What works online: a portfolio page per home, the steps of working with you and a contact form for buyers who are still comparing builders.

Washington County as a whole had 371 employer establishments in 2023 and another 1,256 nonemployer businesses, the one-person shops and independent contractors that often have no website at all. Compared with the U.S. as a whole, Washington County leans toward trucking companies (27 establishments, 3.6 times the national share). In that business, shippers and brokers vet carriers, and the website should show lanes and regions, equipment, authority and insurance details and a quote form. Next on the list: social assistance and child care providers, 18 of them, at twice the national share. For any of them, a clear website is the difference between being compared and being skipped.

Missouri rules to know before your website goes live

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

  • Newsletters and promotions sent from your business email must include a working way to unsubscribe (16 CFR Part 316). 16 CFR Part 316
  • A federal rule (16 CFR Part 465) makes it unlawful to write, buy or sell fake reviews and testimonials, so the reviews on a business website have to be real. 16 CFR Part 465

This is general information, not legal advice; check with the Missouri agencies, Washington County, the city of Potosi or an attorney.

Potosi web design FAQ

I work in Potosi and nearby towns. Can the website say that?

Yes. Tell us by email which towns you cover, Bonne Terre and Leadwood included, and they go on the website’s service area page.

Potosi is small. Do I really need a website?

Your market is bigger than the city: Washington County has 1,256 nonemployer businesses and 371 with employees (2023), and customers search across the whole area. A website is how people outside Potosi find you.

Can the website say I serve the whole of Washington County?

Yes. The plan is the same anywhere in Missouri, and the website can name every town in Washington County you cover.

Is there a setup fee?

No. No setup fee: you only pay the $89 monthly fee, after you approve your website. There is no lock-in contract either: you can end the service whenever you need.
