I went with it, despite your advise... (1)
What up everyone, I know I have read a million times not to use ladingpage software but I ended up using leadpages to create my A/B split test. I was impressed that is beside the point.
Leadpages tracks conversions through opt-in. I have created a clickthrough landing page that take you to the offer page. So in order to track conversion A/B, I need to implement a thank you page. When the person reaches the thank you page with whatever version of landing page, it would track from which Landing page A/B they came from.
So now the questions is how do I set it up. Click image for larger version.
In the decisive editing ad, inside url, I presume I put the landing page URL but do I still add =campaign name=&s2={{{bidhash}}}"? The second question is, How do I make sure that when they conversion happens, they go to my thank you page? Again I presume I add the landing page URL in the Postback URL 
Let me know your thoughts. This is for mobile ad. And I have already asked leadpages support, they are not too sure. My AM says he will get back to me on Monday. In the meantime, I thought I try asking STM.
