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.
A sales funnel is a marketing system. It’s the “ideal” process you intend your customers to experience as they go from Prospect to Lead to Customer to Repeat Buyer. Sales funnels have been around much longer than web marketing, but the online world is the best thing to ever happen to sales funnels because websites and email marketing make sales funnels easier to build.
Now your marketing automation funnel is giving you a boost at every stage: It responded within five minutes of their first contact, and that helped get you the chance to make your pitch. Now, after the pitch, you're ready to stay in contact and respond to objections in a friendly, targeted way. (And if they love the pitch, automation can help you stay in close touch until closing.)
