Some good questions to ask: Can they show you some examples of past projects they've built in Webflow? Do some checking if their work looks good on smaller devices (Webflow cascades styles down from desktop, so mobile design can sometimes get overlooked) Are they using a class framework (e.g., Client-first, Mast, Lumos, or custom)? And are they comfortable building the site with a level of modularity that enables easy reuse of sections, components, and styles? This approach simplifies future design updates and makes it easier for your team to manage and expand the site after the handover. What's their approach to SEO in Webflow? What do they do to ensure performance and loading speed are optimized? Do they have a process QA and testing before launching a site? How do they handle client feedback and revisions? Do they have a process for educating you on how to use and manage the site they built?
