If you want to send mobile traffic, GT requires a LP. What type of LP's work for mobile traffic?
Ideas?
Yeah. Super-simple LPs. Very very light images. Loading times are the biggest reason you'll lose people.
The best-converting LPs are the ugly WAP pages (even if you're advertising on smartphones).
Think:
* logo/image (4-8kb max) - not a necessity
* Headline / call to action
* Form
* Button
Don't over-complicate it.
They have one choice - enter their info & hit submit or X out.
Split test header image vs. no image.
Split test headlines / calls to action.
Split test button text.
You can also change the background color using simple HTML.
SP has some nice mobile landers, you can draw some inspiration from them.
Ask your SP rep for their mobile landers.
Yes free iphone, ipad and survey are all old and boring, but they work. Have you tried things like videos, apps or ringtones?
How about credit cards, meet singles, shopping discounts, etc? Not sure, but good luck! 
meet singles? how would that work? im single and lonely enter your phone number here? lol
I've never done coreg but maybe meet singles, enter your number to chat... then redirect to a chat offer, then more offers? lol I could be way off but I thought that's how coreg works. Again, I've never even touched coreg and don't know much about it so sorry if I'm way off.
