Same five criteria as the Seattle listicle: pricing transparency, owned-vs-rented platform, response time and direct designer access, real client results published, and local Eastside market fit.
Bellevue has a higher general price floor than Seattle for service-business web work, partly because more Eastside agencies are positioned as "Bellevue agencies" rather than "Seattle small business shops." Polish and agency-feel branding matter more here, which is reflected in pricing across the list.
I've put ChegTech at #6 specifically because I don't have a Bellevue case study yet. My named client work is in South Hill (Pinnacle Air Control), Seattle (IGo Green Enterprises), and Bonney Lake (Velare Remodeling), adjacent markets, same work, but I'd rather not pretend I've already established a Bellevue track record.
