A) After two weeks of the campaign first sewing impressions. Gotta let the campaign run for a bit before measuring.

C) Before the campaign serves any impressions. This is the only way to create a true control group.

I think it might be best to set it up after the campaign starts, like option D, to capture real-time data. But I’m not completely confident about that choice.

I recall that having a control group is essential, so maybe option C is right? But what if we miss some initial impressions?

I'm not entirely sure, but I feel like setting it up after the campaign starts might lead to some bias in the results. I remember a similar question where timing was crucial.

I think the study should be set up before the campaign serves any impressions, so we can have a clear control group. That seems like the best way to measure the impact accurately.

I'm leaning towards B. Waiting until the campaign is over seems like it would give you the most complete picture of the lift. But I could see the logic behind C as well.

Option D seems like it could work too, but I'm not sure if that would give you enough time to properly set up the study before the impressions start rolling in. C feels like the safest bet.

I'm pretty confident that the right answer is C. You need to have a control group that hasn't been exposed to the campaign at all in order to accurately measure the lift.

Hmm, I'm a bit confused. Wouldn't it make more sense to set it up after the campaign has been running for a bit, like option A suggests? That way you can measure the impact over time.

I think the key here is to set up the study before the campaign starts serving impressions, so I'm leaning towards option C.
