What’s the most important aspect when creating a freebie optin for my website?

It has to be something they really crave! Don’t be fooled thinking that something has to be a lot of pages or even fancy for people to crave it. For example, I knew a consultant who helped college grads get into med school and his freebie opt in was “10 Words you MUST use on your med school application if you want to be accepted!” It was a simple 1 pager that his ideal client hungered for and he attracted thousands of opt ins for it. Sometimes less is better 😉
