Hey nice post!

People really should look into the actual optin pages they create to optimize.

Just changing from "sign up" to "send me my free report" can change everything.

In optin pages:

1. Use an action button "get instant access" instead of "submit".
2. Test different colors especially for the button. Red or orange usually works best.
3. Keep your offer simple in your optin page. Give people one simple trick in your niche not a whole ebook.
Even though you don't think that 1 trick is as valuable as a whole ebook but it's just not what people want.
4. Make your offer specific and interesting. Make visitors wanting to see more!
5. Test Test TEST!! You may be surprised how easy it is to double or triple your optin rate.
