Ok lets say we have some offer, ie Credit Score tha twe normally drive stright to offer and converts a bit.
If we change that to coreg [so 1st we gather lead, then it auto goes to the offer itself where they fillup more data/or the data is passed and they have to click.
What are chances the lead might be lost this way due to passing 2-3 times same data?
Or maybe i think wrong and the corteg is 1st makes em entr just email [minimum data], then hooks them to enter more since htey entered the email already.
As you know Credit leads are way more then email, so im not asking for simple email submit.
Somebody skilled and who tested those please explain advantage of coreg and hows it should be properlymade for me to bank 
Is that totally dumb question or you guys lazy 
I'm just getting into doing some Co-reg myself, but I think the simple answer is to test, just like anything else. ;-)
Test it and check what makes your more money LTV ... lifetime value.. or RPU ... revenue per user
For example
If you run a lander that collects say his name, age, email... then you work it to step 2 where he fills out more shit to get
say a payday loan. You will get a % that complete step 1, and then less will do step 2.
Where if you just sent to step 2, you'd get more people than that will do step 1 and 2.
However, you need to test, to see what the % you lose is, and then decide if collecting the data
is worth the % you lose.
