FuFu: Follow up Funnel sales funnels are for repeat customers. These funnels maximize the value of each customer over the lifetime of the relationship. To do this, you will follow-up and send customers to other sales funnels that offer more expensive products. For example, customers already purchased your $37 product in sales funnel #1. So in sales funnel #2, you can offer a $297 product. In sales funnel #3, you can offer a $997 product.
In housing terms, VPS hosting is like renting your own apartment in a larger building. You're much more isolated than in the roommate situation mentioned above; it's still possible that a neighboring apartment could causes annoyance for you, but far less likely. In web hosting terms, Site A's traffic surge won't have nearly as much impact on Site B or Site C. As you'd expect, VPS hosting costs more than shared hosting. You'll pay roughly $20 to $60 per month.
WordPress started off as a blogging platform but has evolved to be a great platform for business websites too. As such, you have a way to specify what shows up as the home page for your WordPress site. If you have a blog, you’d want your visitors to see a list of your blog posts. If you have a business website, you’d want your visitors to see a home page (static page).
While the the best of them offer surprising amounts of flexibility, they also impose stringent enough restrictions to page design that you shouldn't be able to create a really bad looking site using one of these services. Typically you can get a Mysite.servicename.com style-url with no commerce abilities for free from one of these services; you have to pay extra for a better URL and the ability to sell. One issue to consider is that if you eventually outgrow one of these services, it can be hard to export your site to a full scale advanced web hosting like Dreamhost or Hostgator. If you know that's where you are eventually going, it may be better to skip the sitebuilder step.
