Hi there,
I've been running my first campaign for just about three days now. On the second day I had my first profitable day (20.94% ROI) which surprised me as it was the second day.
I tested seven ads and kept those with CTR > 0.25%. As well, I'm split testing two different adult offers with 4 landing pages overall. I created a Multi Patch Campaign in CPVLab to do so.
lpA => Offer A
lpB => Offer A
lp C => Offer B
lp D => Offer B
I noticed that lpB and lpD didn't perform as good as lpA and D so I trashed them (They had a MUCH lower CTR and conversion rate). Right now I'm still in a negative ROI though and I'm not looking to stop with this. I want to succeed. I spend daily $50 on TrafficJunky and target German Offers. I believe that I found one offer that I could turn into a profitable campaign but I'd need to know what I should optimize first? The ad or the Landing Page? I trashed a few ads that didn't convert as well. I feel a bit unsure though as I had like 11 conversions on Monday and only 2 on Tuesday.
My Campaign looks like this so far:

(Without the lucky Monday, the ROI would be even more negative)
Hopefully I'll get some help

Are you making sure that your results are statistically significant before killing your ads? Part 10 of the Getting Started Guide covers this - you need to be sure that the ads which are / aren't performing are doing so because of a consistent trend and not just randomly.
The same applies to your Landing Pages - part 11 of the Getting Started Guide covers this.
Also, is there a reason you wanted to set up your campaign the way you did? Normally I'd just recommend rotating landers and offers separately using CPVLab's default rotation setup.
Congrats on profit in day 2, though - now's the time to build on that, carefully!
Thanks for the reply.I usually kill landing pages that have 200 visitors and convert worse than other landing pages or a CTR < 30%.
Btw, I set up the campaign like this because the style of the landing pages are customized to the offer (Color). E.g The offer has a blue design = I create a landing page with blue as well.
