I think I know why it might not work at the moment.
Apparently your domain provider as directed that domain to one of their default IP servers where it displays this default page:
The about this page link says:
This homepage was created automatically when you registered your 1&1 domain package or hosting package. This homepage is only temporary and can be replaced with a website you create at any time (please refer to point 3 below).
I would ask them to change this, and possibly give them the Unbounce IP.
Now, I don’t know why google is not indexing your page but they usually take their time with this. To speed up and help google I would advise you to register to Google Webmaster Tools.
Hope this helps.
Ps. Your page look awesome!
