So I have a theoretical question regarding drilling down into mobile traffic and volume.
Lets say on a given traffic source I get 1000 clicks/day (500 android + 500 iphone).
Now lets say I feel like android traffic isn't working for me, so I target only iphone.
Now in theory if I don't change the bid I would expect to get the same amount of iphone traffic (500/day).
However it seems like when I target iphone only, I may get only 350-400 clicks a day. There is a loss somewhere.
Is this normal?
Could be just incorrect OS detection of the source or in your tracker.
Let's say you were buying traffic without ANY OS targeting ... you would get your 500+500 and some other OSs on top of that. Now you chose just iOS and get 400 ... the remaining 100 can be iOS users that the source wasn't able to detect, it could be BOTS that your tracker identified as iOS but the source didn't get fooled or it were users on other OSs that your tracker identified as iOS.
The other option is some kind of "penalty" issued by the source to buyers who optimize to much. I've seen this a couple times already, the more I optimized the less traffic I was using, even from targets that I didn't touch.
It can also have something to do with bidding, maybe some competitor raised their bid on iOS around the same time.
Hey Matuloo thanks for the input.
Always appreciate you taking the time to answer my questions
