I think https://webflow.com/editor will certainly be a help. However, I think a few more testimonials from actual businesses (i.e not developers or designers) who have switched from WordPress to Webflow would be useful. The testimonial on the page at the moment is from a developer which is unlikely to resonate as much with a potential client. It also mentions Squarespace and although I understand the point being made, it is something I would avoid. A client may not have heard of Webflow and if they skim read and see a comparison to Squarespace they may get the wrong impression.
A bullet pointed list comparing Webflow and WP would be useful. That appears on https://webflow.com/vs/wordpress but is focused on the designer / developer point of view.
I think the links at the bottom to see what’s been made in Webflow and finding a Webflow designer muddies things a little. Easy for a client to get confused between the Webflow editor and the CMS (which is really what this page should be about).
Just a few thoughts. Overall though, its solid!
I think selling in Webflow CMS vs WordPress is a conversation lots of Webflow users face so would love to hear some other ideas.
