Webflow mentions Blogs many times in their videos and documentation, but in fact there is no way to create a blog using Webflow. That in spite of the fact that users have been asking for that capability for more than 4 years.
Even using Zapier, it looks like you should be able to implement a blog, but I don’t think it works. It only works by manually updating a row in a google sheet which then updates your CMS. But there is no way for users to update your CMS on a Webflow page.
If I’m wrong I’ll admit it, but I’d love to know how to do it.
