Hi,
The 2008 Obama Presidential campaign used split testing to generate an extra 288,000 signups and volunteers,
AND an additional $60 million in donations over the course of the campaign...
They managed to increase their optin conversions from 8.26% to 11.6%, that's 40.6% more signups from the same traffic!
and with the right tool it's easy for you to do the same for your optins AND sales
The important bit here is you don't need to be tech savvy or some massive 'big budget' corporation to take advantage of this technology
I've done a quick walk through video showing how easy it is to use my favorite split testing software here:
