  • Flooring contractors, 4 in the count. What works online: photos by floor type (tile, wood, vinyl), the areas you cover and a form to book an estimate visit.
  • Insurance agencies, 8 in the count. What works online: auto, home and business coverage on separate pages with a contact form for quotes.

Across Union County, County Business Patterns counted 14,276 employer establishments in 2023, and the Nonemployer Statistics add 58,308 businesses with no payroll, most of them self-employed owners. One sector stands out in Union County: transportation support businesses, with 178 establishments and 2.2 times the national share. What works for them online: services, locations, hours and a way to request service. Trucking companies are also overrepresented (502, 1.7 times the national share). The jobs Mountainside residents hold are mostly in education, health care and social assistance (18.5%) and professional, management and administrative services (16.6%). For any of them, a clear website is the difference between being compared and being skipped.

Website design for the people of Mountainside

The median home here was built in 1957. That means steady demand for repairs and renovations. With 24.2% of the population at 65 or older, Mountainside is older than New Jersey as a whole (17.2%). A website for this audience should be easy to read on a tablet, with large buttons and a clear way to get in touch.

7.6% of Mountainside residents speak Chinese at home. Customers who grew up with another language skim for prices, hours and a contact button.

New Jersey rules to know before your website goes live

Some homework before launch:

  • New Jersey charges a single statewide Sales Tax of 6.625% on most tangible personal property, specified digital products and certain services; there is no general local sales tax, though reduced rates apply in Urban Enterprise Zones and Salem County and Atlantic City has its own structure. New Jersey Division of Taxation
  • 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
  • A corporation, LLC or LP that does business under a name other than its legal name registers an ALTERNATE NAME with DORES ($50, effective for five years, renewable). Sole proprietors and partnerships instead register a TRADE NAME with the county where the business is located. Official source

Rules change and details vary by business; this is general information, not legal advice.
