General question - Let’s say I’d like to AB test like this
Have one campaign with keyword1, and second campaign with keyword1 & keyword2.
Can I be sure those campaigns will run on disjoint users data set? no overlapping in the target crowd?
No, you will target same users.
so is it posible same user will see twice my ad?
Exactly,
Even with the same campaign, if you don’t limite frequency an user could see the same ad
Here:

requency_cap
optional
An integer representing the number of times for which one user could be delivered an ad to.
Example Values: 5
duration_in_days
optional
An integer representing the time period within which the frequency_cap frequency is achieved. Only supports values of: 1, 7 and 30.
Example Values: 30
I think you should have an special feature activated. If it’s needed, you should talk with your ads account manager (nothing related with API, I guess)
Thanks
