Very comprehensive review of funnel hacks. I’m glad to see that you actually have it and honestly review it. The cost is rather high, and I think it may not be the best for beginners. i think they may be overwhelmed with funnels if they are just starting out. However, if they have the cash and time to invest, I’m sure that it would benefit them greatly.
It's no surprise Unbounce is near the top of this list -- they've actually written the book on creating high-converting landing pages. Although there are lots of amazing things about this landing page, the two that I absolutely love are: 1) The use of a chat window instead of a classic form, and 2) the detailed -- but well packaged -- information below the form.
Imagine an autoresponder that doesn't just send emails, but allows you to track which channels your visitors are coming from, segment them based on actions they take and who they are (what they do in your funnels, how socially connected they are, what they purchase and more!), create custom follow up sequences (email, text messages and more!) for each visitor and FINALLY see the TRUE Lifetime Value of each of your customers!
