I would like to know how I can analyze the visit flow by type of acquisition channel ex:(direct,natural search, paid search and others) and its navigation within the site until lead generation.
Unfortunately, there's not an easy way to do this.
The best that I can think of is to build a dashboard with all of the navigation reports that you want. Then at the top of the dashboard, drag-and-drop the "Marketing Channel" dimension into the dashboard-level segment area. Now, you can toggle between your various Marketing Channels and the dashboard will update with the data relevant to that channel only.
