Watertown is a manufacturing city: 19.8% of employed residents work in factories and plants. Web design in Watertown has to show capabilities, not slogans. Here is the offer: $89 a month for the website, domain, business email and hosting, no setup fee, and the first payment only after you approve what we built.

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

What makes Watertown different, and what your website should do about it

Watertown is the seat of Codington County, which puts the courthouse and county offices in town. Visitors who come in for county business usually need something else while they are here: lunch, a copy shop, a notary, a mechanic. A page listing the towns you cover helps the people who come in from outside Watertown.

Watertown is on Interstate 29, so some of the people looking for food, fuel, lodging and repairs are just passing through. Highway traffic also brings freight: trucking, repair, towing and parts suppliers serve people who will never live in Watertown. One screen with services, hours and location is what a traveler needs.

Which Watertown businesses need a small business website

Watertown shares ZIP code 57201 with the surrounding area, where 1,166 employer businesses were counted in 2023. A few examples from the same count:

  • Hardware stores: 9. Their website should show departments, store hours and services such as key cutting or rentals.
  • Custom home builders: 16. Their website should show floor plans and photos of homes you have built, the lots or areas you build in and a way to start a conversation.
  • Hotels and motels: 15. Their website should show rooms, photos, location and a contact form, so travelers can compare you outside the booking apps.
  • Insurance agencies: 29. Their website should show auto, home and business coverage on separate pages with a contact form for quotes.

Across Codington County, County Business Patterns counted 1,210 employer establishments in 2023, and the Nonemployer Statistics add 2,358 businesses with no payroll, most of them self-employed owners. The county’s largest sectors by number of employer establishments are retail trade (15.6%), construction (11.2%) and other services (repair, personal care, organizations) (9.7%). Among Watertown residents who work, the largest fields are education, health care and social assistance (22.1%) and manufacturing (19.8%). None of them needs a complicated site; they need one that answers the customer’s first questions honestly.

Paperwork and rules for South Dakota businesses online

  • Under ADA Title III, a business open to the public should make its website usable by people with disabilities, according to the Justice Department’s guidance. ADA.gov guidance
  • 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
  • South Dakota’s state sales and use tax rate is 4.2%, and municipalities add their own sales tax on top of it. South Dakota Department of Revenue
  • 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
