Should my ad labs include an offer?

Edited

If you have an offer that has proven to work in ads in the past, include this offer in your ad lab, as it will most likely stay on your super ad.

If you have not ran ads or an offer before, do not include an offer in your ad lab. This can negatively skew your results if the offer doesn't resonate.
