Website design for Seattle, delivered remotely

We take on website work for Seattle businesses remotely from Malvern, PA, and every stage is reviewed in your own browser.

Why it matters: 110,685 business establishments operated in the metro in 2023, and 86.1% of them employed fewer than 20 people.

Go deeper: how a remote build runs, stage by stage

Health care and social assistance alone holds 15% of the 1,884,361 paid employees counted in the metro in 2023.

Retail trade adds 9.6% and accommodation and food services 9.3%, so three sectors hold 33.9% of the payroll count.

The three cards above are the three largest of the 12 sectors we read for the metro, by paid employees: health care and social assistance, retail trade and accommodation and food services.

Professional services is fourth, with 167,804 paid employees in 14,812 establishments.

  1. Health care

    283,099 paid employees across 13,557 establishments in 2023; a site here needs online booking, intake forms and an accessible path for every patient.

  2. Retail

    180,078 paid employees across 10,161 establishments in 2023; a site here needs stock that matches the till and a phone checkout.

  3. Hospitality and food

    175,473 paid employees across 10,337 establishments in 2023; a site here needs hours, menus and bookings that read on a phone in a hurry.

Websites we built

Six live sites we built open here in a preview window, the same way your build is reviewed before launch.

Why it matters: A working site shows how a build loads, reads and takes an enquiry, which no mock-up can.

Go deeper: how the previews work

Preview opens the live site inside a sandboxed frame on this page. Atlas Peptides blocks framing, so its preview is a dated screenshot instead.

None of the six is presented as a Seattle business; each one shows a job a site has to do, whatever the city.

Between them they cover a configurator that prices as you build, online scheduling, booking with reviews pulled in, a shared stock count, a quote form and a checkout.

110,685 businesses, in public numbers

The metro had 110,685 business establishments in 2023, +2.6% since 2018, by County Business Patterns.

By the numbers: 4,145,494 people lived in the metro in 2024, +4.2% since 2019, and payrolls counted 1,884,361 employees.

Go deeper: what County Business Patterns counts

Of the 110,685 establishments, 95,337 had fewer than 20 people and 12,665 employed 20 to 99. Another 2,360 employed 100 to 499, and 323 employed 500 or more.

Within the 20-to-99 band, 9,559 establishments had 20 to 49 people and 3,106 had 50 to 99. The average establishment employed 17 of the 1,884,361 paid staff.

County Business Patterns counts employer establishments, locations with paid staff, so a sole owner with no employees is not in the 110,685; that is one establishment for every 37.5 residents.

NAICS 541511, custom computer programming, includes custom web page design and all other custom software, so 103.6 per 10,000 businesses is a ceiling on web-design firms in the metro.

Health care leads, with 283,099 employees

Health care and social assistance employed 283,099 people in the metro in 2023, the most of the 12 sectors we read.

Why it matters: who a site talks to follows the sector mix, and retail trade comes next at 180,078 employees.

  • Health care: 20.9 employees per establishment; booking and intake matter most.
  • Retail: 17.7 employees per establishment; stock and checkout must agree.
  • Hospitality and food: 17 employees per establishment; hours and menus must read fast.
Go deeper: who these pages are written for

13,557 health care and social assistance establishments in the metro need online booking, intake forms and an accessible path for every patient. The 10,161 in retail trade need stock that matches the till and a phone checkout.

Accommodation and food services counts 10,337 establishments that need hours, menus and bookings that read on a phone in a hurry, and professional, scientific and technical services, fourth at 167,804 employees, needs proof of expertise, case pages and a routed enquiry form.

Manufacturing ranks fifth at 159,957 employees, and the 12 sectors we read cover 1,563,113 of the 1,884,361 paid employees in the metro.

Together the four employ 806,454 people, 42.8% of the payroll count; the sector figures shape the scope, and the six sites above are our delivered work.

The top phrasing, “web design seattle”, draws 1,000 US searches a month by Semrush’s exact count.

By the numbers: the 4 phrasings add up to 1,660 searches a month, 1,000 of them on the top one.

  • Autocomplete also completes “web design seattle wa”, a phrasing people type.
Go deeper: how we rank every place by the same numbers

We rank every place in the country by the same measure, the sum of these phrasings, and this page sits 20 of the 134 places we measured, at 1,660 searches a month.

The development phrasing draws 260 a month and the developer phrasing 140, phrasings that often signal a build beyond a brochure site.

The company-intent phrasing draws 260 searches a month at about $7.00 a click, the buyer already looking for a firm.

Advertisers paid about $8.60 a click for “web design seattle”, which is what a search costs to buy, not the price of a website.

The top phrasing, at 1,000 searches, carries a Semrush keyword difficulty of 21 out of 100.

1,147 custom programming firms in the metro

1,147 custom computer programming establishments (NAICS 541511) operated in the metro in 2023, −8.3% since 2018.

Yes, but: that code also covers all custom software, so 103.6 per 10,000 businesses is a ceiling on web-design firms, not a count.

  • Graphic design (NAICS 541430): 270 establishments in 2023.
  • Marketing consulting (NAICS 541613): 825 establishments in 2023.
  • Advertising agencies (NAICS 541810): 194 establishments in 2023.
How to choose a web design company
Go deeper: how to compare the firms on your list

With 1,417 programming and graphic design establishments in the metro, ask each firm for live sites you can open, who will own the code and domain, and a written scope.

The wider NAICS 5415 group, computer systems design and related services, counted 2,621 establishments, 236.8 per 10,000 businesses.

Marketing consulting (825) and advertising agencies (194) often sell websites too, so the full field in the metro is wider than the programming count.

Custom programming establishments went from 1,251 in 2018 to 1,147 in 2023, while graphic design stood at 270, 24.4 per 10,000 businesses.

Those 1,147 programming firms employed 23,012 people, about 20.1 each. The wider 5415 group employed 44,474.

From 107,883 to 110,685 businesses since 2018

Establishments in the metro rose from 107,883 in 2018 to 110,685 in 2023, a change of +2.6%.

The bottom line: health care and social assistance grew the most of the 12 sectors, +12.1% in establishments, while wholesale trade moved −11.8%.

  • 20 to 99 employees: 12,652 establishments in 2018, 12,665 in 2023.
  • 100 to 499 employees: 2,288 in 2018, 2,360 in 2023.
  • 500 or more employees: 266 in 2018, 323 in 2023.

Go deeper: what the change means for a website

Health care and social assistance went from 12,089 to 13,557 establishments between 2018 and 2023; wholesale trade went from 5,306 to 4,679.

Real estate, rental and leasing came second, +9.4%, and construction third, +7.9%.

That is a net gain of 2,802 establishments: each new one needs a first site, and each established one carries addresses and rankings a rebuild must keep.

Paid employees went from 1,773,052 to 1,884,361 over the same years, +6.3%. Population moved +4.2% from 2019 to 2024, to 4,145,494.

Ranked 28th of 64 places by businesses

The metro ranks 28th of the 64 places we build pages for by business establishments, and 19th for programming firms per 10,000 businesses.

By the numbers: population growth since 2019 ranks 32nd of 64, and the share of establishments under 20 staff ranks 14th.

Go deeper: why every place is measured the same way

Every place page uses the same Census tables, so these ranks compare like with like: 110,685 establishments here against the 64 places' own counts, 43rd for their change since 2018.

Programming firms run 103.6 per 10,000 businesses here against a median of 85.2. The under-20 share is 86.1% against 84.4%.

The 64 are the places whose web design searches clear 500 a month in Semrush's exact data, state pages counted with any places folded in; this one draws 1,660, 20th of the 134 places we measured nationwide.

How a Seattle web project runs

A project here runs in the same five stages as every build of ours, from agreeing what the site is for to launch.

What you get: the scope, price and schedule in writing at stage two, before anything is designed or built.

How a custom website build runs
Go deeper: what happens at each stage

Stage one fixes who the site talks to; in the metro, where health care and social assistance employs 283,099 people, that answer often sets the integrations.

Stage five hands the site over in your own accounts, a handover any of the 2,621 systems design establishments in the metro could pick up from.

For the 10,161 retail trade establishments here, stage two usually lists stock that matches the till and a phone checkout.

The five stages in order; the written scope, price and schedule come at stage two.

  1. Agree what the site is for

    Who the site talks to, what it must get them to do, and what it connects to.

  2. Scope, price and schedule in writing

    Pages, integrations, price and dates on paper before any design starts.

  3. Design in the browser

    Real content at real widths, reviewed on your own phone as it takes shape.

  4. Build and wire it up

    Code, forms, CRM, analytics and accessibility checks, in one pass.

  5. Launch, hand over, stay on

    The site goes live in your accounts, and we stay on for support.

Working with us from Seattle

Seattle runs on Pacific time, so our 9-to-5 Eastern day is 6 a.m. to 2 p.m. there.

The bottom line: the office answers (610) 890-9711 Monday to Friday, 6 a.m. to 2 p.m. local time, the day 1,147 programming firms here keep.

Do you have an office in Seattle?

No. Our one office is in Malvern, PA, and projects here run remotely, with every stage reviewed in your own browser.

Go deeper: calls, reviews and where the work happens

Calls and screen-shares cover the whole build, and you review the work in your own browser between them; no branch office or answering service sits in between.

Web design questions from the metro

Not answered here? Call the office: (610) 890-9711

Yes. We take on website work for Seattle businesses remotely from Malvern, PA, and every stage is reviewed in your own browser. You deal directly with the people designing and coding the site, and calls are set in Pacific hours, the clock the metro's 110,685 establishments keep.

The scope sets the price, not the ZIP code: pages, integrations and what the site must do, for one of the 95,337 small establishments here or a larger one. You get the price and schedule in writing first; advertisers paid about $8.60 a click for the main web design phrasing here (Semrush).

How much does a website cost?

Hire a designer when the site has to book, quote, sell or connect to a CRM; a builder fits a site a standard template can serve. In the metro, 86.1% of establishments employ fewer than 20 people, so we say which route fits before quoting anything.

Squarespace, Wix or WordPress versus custom

Yes. Titles, headings, page speed and schema go in while the site is built, and Search Console is connected at launch, so the 1,660 monthly searches (top phrasing 1,000) in the table above are targeted from day one. “web design seattle” alone draws 1,000 a month, by Semrush’s count.

SEO services

Open the live sites a firm has built, ask who owns the code, domain and hosting, and get the scope and price in writing. With 1,417 programming and graphic design establishments in the metro, and 103.6 programming firms per 10,000 businesses, those three checks shorten the list quickly.

How to choose a web design company

Not when every old address is mapped to its new page and redirected before launch, so rankings and links carry over. For any of the 110,685 establishments in the metro, that map is the first thing a rebuild of ours produces.

Website redesign

Yes. We build to WCAG 2.1 AA: keyboard paths, contrast, labels and headings checked before launch, with no overlay and no certificate claimed. It matters most for the 13,557 health care and social assistance establishments in the metro, whose patients include people of every ability.
