First time use propellerads, only several minutes.
Get lots of click from computer, mobile only few click.

Hey,
CTR depends from more aspects on Propeller.
First of all I highly recommend you to separate campaigns for mobile and desktop so your "CTR not mix up" from these 2 devices.
Also bids will be different for each device type as different people buy these clicks.
Another thing that will HIGHLY affect your CTR is the user age. Also I recommend you to run split test for different user ages (HIGH, MEDIUM, LOW), usually the HIGH will yield you the highest CTR whereas the LOW will be the lowest one (though clicks will be cheap)
Thanks
yes, i separate campaigns already, you can see picture, 5 campaigns for computer, 5 for mobile.
The same show, the click difference is very big, I don’t know the computer click is a robot or not
I see, I did not run desktop on propeller for a while, but those numbers seems to be quite low to be honest. What was the user activity that you set there?
Are you using exactly the same ads for both the mobile and desktop campaigns? With my campaigns, I see different ads performing well on each device type. But to be fair, the difference is not that dramatic.
Then there is the bid, I see you are bidding a bit higher for mobile, but maybe it's still not enough. The competition can be quite different on mobile vs desktop, so the same bid might not cut it. Maybe you are better positioned in the bidding chain on desktop, so the CTR also reflects that.
And there is still the BOT option ... did you try to analyze the traffic on a deeper level? Do you see several clicks from the same IP in the desktop campaigns, for example?
I would suggest increasing your mobile bid to give yourself a more competitive spot in line and thus more quality impressions.
Bots. Desktop is almost all wifi traffic, so it's very easy to run bots. And there is a fuck ton of them. That's why desktop traffic is cheaper, generally. Only way around it is a lot of bid testing and blacklisting. And patience.
The inverse is also true. It's harder (well, prohibitively expensive) to run bots on a real 3G carrier connection, so it's almost all real traffic. This is why mobile carrier traffic is usually much more expensive than wifi, and doubly so against desktop.
