Hey guys,
I have been running a campaign recently and finally got it into the green for the last 4 days.It's an CPI app install paying $0.33 per conversion, traffic source is domain redirect/popup. Here are the stats so far:
Day 1 - +21.43% ROI, $15.31Profit
Day 2 - +40.07% ROI, $22.37 Profit
Day 3 - +67.66% ROI, $30.90 Profit
Day 4 - +63.07% ROI, $49.26 Profit
I am still consistently testing new elements for my landers. Right now I am trying different photo's as I have just read that stock photos are not the best pictures to use.
At this point of the campaign, if the ROI holds for the next few days, do I try to scale this campaign? The profit is low but the ROI seems promising so far. Unfortunately, it seems that my traffic source does not have more traffic for this particular geo to offer. I am bid position 2 and have not noticed a big difference in traffic when I am the top bidder, other than paying more for roughly the same amount of traffic.
What should my next step be for this particular campaign? Should I try the same offer in the same geo on different traffic sources? Or do I try different geo's of the same offer on the same traffic source?
As always, your advice is much appreciated 
If the offer supports multiple geos then I would test both.
First try other geos on your traffic source since you are already familiar with it.
After you do that start testing similar traffic sources with whatever worked on this source.
Keep us updated how it goes mate!
