DFP clarifications that aren’t in the tutorial

(written by TheChiro)

I’m still sooo freakin’ confused by this. Hopefully someone can help shed some light for me. This is what I want to do:

• Medium Rectangle [MR] within threads (guests and members – not staff or premium)
  Responsive with Mobile unit
• MR ATF in guest welcome message (just guests)
  Responsive with mobile unit
• Leaderboard [LB] between pagination and reply box at bottom
  Responsive with Mobile and Full Banner [FB]

Now here’s where I get confused. I need to make those as Ad Units. So that should be a total of 4 ad units? Or would each of those need to be a separate ad unit, which would be 7 ad units? The more confusing part then…Placements.

I plan on going to advertisers and allowing them to target specific forums. I thought I read a way to target sections with custom code within the line item creation (?). I’m not sure how to do that at all, if that is even a thing. Would there be a better way?

And then when I go to apply the code, how do those placements I just created work then? Because it looks like when I generate the code, it is only for ad units, so how does that work with the placements are being able to target sections?

I think I may be over complicating this and over thinking it. I really want to get DFP going, just every time I look at it, I get confused and frustrated.

And then the last thing, how do you recommend going responsive with DFP?
