Can I just use my home page as my landing page for sales?

While many businesses do this, in our view, this is not the best option for many reasons. When a prospect sees your compelling call to action, it should be based on the one thing they are looking for. When they select the option to find out more, they will want to see only the information they are interested in, not the full range of options. The more options you give them, the less likely they will take the action you want them to take. Please keep it clean, keep it simple and focus on the one thing they want via a well-constructed landing page.
