Websites and online stores are a thing of the past. The future belongs to online sales funnels. I found a tool called "ClickFunnels", and it rocks! Wouldn't it be great if Weebly would build features like that?
Thanks for posting, @DvdS! Any particular features from that you'd like to see added?
Please read this: https://s3content.s3.amazonaws.com/funnel_hackers_cookbook/TheFunnelHackersCookbook.pdf (especially section 3)
or watch the videos (especially the last):
The idea is to lose the navigation and build a sequence (funnel) from a landing page just like stacking lego. Then you need specific elements on the pages to convert visitors to buyers.
Why don't you try to build some of the funnels from this cook book using Weebly and see where you get stuck?
Here's a short demo: https://youtu.be/Bm87CiNnyZw
