When To Use Pre-Landers

[dondaff]

The Scenario:
Traffic Sources: Push & POP
Verticals: Gambling & Dating
Side Topic: Smartlinks

Assumptions:
Pre-Landers for both Dating & Gambling should be short and sweet when using Push and Pop traffic

With that said, I need answers for the following questions, so I can determine whether a pre-lander with hurt or help conversion rates:

1. Do I need pre-lander for a single dating offer?

2. Do I need a pre-lander for a single gambling offer?

3. Do I need a pre-lander for a dating smartlink?

4. Do I need a pre-lander for a gambling smartlink?


I have obtained mixed answers regarding these scenarios and just needed further information, opinions, and expertise.


Thanks
