Google Web Designer allows designers, or BAU staff to build rich media content without holding skills only possessed by web developers. It's an industry standard platform to build on, plus has additional benefits when producing digital content for multiple outputs, all at once.
GWD was purpose built for creating rich media items, which is often used by graphic designers, or ,marketing teams within organizations, in particularly when trying to advertise products and/or services online.
GWD has animation functionalities too, including audio and video. So it differs a little to Adobe's Dreamweaver, and is more 'user-friendly'.
