Think about all the sites you visit once and never go back. You just had no good reason to return. The same thing is going on with your site every day. When you get a visitor to your website and they leave, You have a pretty fair chance they won't return, unless you give them some kind of reason to do so. We all get sidetracked on the web, and navigate away from a site, never to return.
The point is to find a way to grab these visitors so we can give them a reason to return. If thousands of visitors hit your site, read a little, and move on to the next page, you don't make a dime of profit. What if you could convert some of those visitors to paying customers?
Your content is definitely important. It needs to grab their attention. After you have their attention, you need a way to turn them into paying customers. The real, long-term solution lies in converting your visitors to subscribers.
Before the visitors leave your website, you want to convert them into subscribers via a simple opt-in to your mailing list. You do this by asking for your visitor's name and email address through an opt-in form.
If your visitors sign up for your free product, you can then follow up with them via email to present them with any new products or information you would like to sell them.
The main objective of your home page should be to convert as many visitors into subscribers as possible. This will help you regain the revenue you have lost in the past, and also will give you a targeted prospect list for any future products you are selling.
