Just wanted to share a few words from an email I got from Richard of the band Enation (a fellow IC member). This really goes to show how the smallest tweaks can dramatically change things.

"Another shout out to your Insider's Circle Modules. I ran a FB campaign and noticed that 70 + % of the users were on their mobile device. I looked up the module on 'Mobile Squeeze Page' and added the Mobile version -- and overnight went from 21% conversion to DOUBLE that 42% and it held strong throughout the rest of the campaign. I was thrilled w/ that result. 

I also took your advice and changed out the generic Aweber 'Submit' web form on our website and used the 'Download Now' button instead -- and again overnight it doubled the opt ins on our main site. "

If you are one of those people who can't seem to crack the 15% opt in conversion ration, it's easy to see how just one of these changes could turn a losing campaign into a winner. (Assuming everything else is equal and the changes got you the same result).
