In my Online Sales Funnel presentation, I mentioned how important having multiple landing pages is in your overall strategy.
Here's a video that shows you the components of a Landing Page. When I first started creating landing pages, I used a company called Leadpages. They make it very easy to do and will even help to walk you through the Facebook Ad set up upon completion of your landing page.
As I've become more advanced, I now simply use a template on my WordPress website. There are many companies out there you can use to create landing pages. It doesn't matter who you use. What matters is that you use the landing page as the first step in your sales funnel and it's something that can easily be created where you have control.
In my second presentation, I discussed the many ways that I automate the processes in my sales funnel.
