The short answer

For mid-market B2B, we design desktop-first then adapt mobile. Mid-market B2B traffic is 60-75% desktop — the dominant conversion surface is desktop, and mobile-first design forces compromises that hurt the surface that does most of the actual work.

№ 01The longer answer

The ‘mobile-first’ rule is correct for consumer brands where 70-90% of traffic is mobile. It’s wrong for mid-market B2B where the buyer is at their desk during work hours. Our analytics across 200+ mid-market B2B sites: 62% desktop, 35% mobile, 3% tablet.

What designing ‘desktop-first’ means in practice: hero hierarchy, section layouts, and visual flourishes are designed for the desktop experience first, then adapted to mobile. The mobile experience is treated as a faithful subset of the desktop experience, not a separate design.

What we ALSO do: ensure mobile is excellent. Mobile sticky CTAs, click-to-call buttons, single-column layouts, larger tap targets, optimized loading. The mobile experience is engineered to convert — it’s just not the surface we optimize hero hierarchy for.

Where ‘mobile-first’ makes sense: B2C consumer apps, local services with high mobile-search behavior (plumbers, HVAC, restaurants), and any site where mobile is 60%+ of traffic. For those, our design priority inverts. We check your analytics before committing to either direction.

№ 02Will my B2B site work on mobile?

Yes — every site ships mobile responsive with WCAG 2.1 AA on mobile. The question is which surface gets design optimization priority, not whether mobile works.

№ 03How do you decide between mobile-first and desktop-first?

Your GA4 data. If mobile is 50%+ of conversion-driving traffic, mobile-first. Below 40%, desktop-first. Between 40-50%, we discuss the trade-offs.

№ 04What about tablet?

Designed but not optimized as a primary surface. We use the same layout as small desktop. Tablet traffic is typically 1-5% on mid-market B2B.
