Hey Everyone,
I've launched and completed my first campaign attempt with -39% ROI. Honestly, I was expecting much worse results and I'm very happy with that number. I've filtered a few geos based on Amy's instructions and will post a follow up once my second trial is complete.
I do have a couple of questions though. It seems like there's a ceiling to the amount of profitable traffic I can get in front of, is this mostly due to the specific filtering I've applied to my PopAds campaign?
There are roughly 575 matches/sec for my geos, though only about 40 of those match the rest of my filters. Does this mean that I only have a chance to convert 40 times/sec versus 575, based on things such as device type, browser, etc.?
I guess what I'm trying to get at is, it looks like my campaign isn't taking significant advantage of the available traffic in my selected geos, which in turn would limit scaling potential. Is this assumption correct, or am I way off base here?
I've included a sample image of my PopAds graph for reference.

Hi Again,
Following up with my end of day results. I pared down my list of geos pretty significantly and managed to cut my losses by more than 1/2.
Tomorrow, I'm going to build separate campaigns for each geo, excluding EC, as it seems to be the worst performing of the 5 and I don't want to juggle more than 4 on my second day. I'll start working through excluding underperforming sites and see if I can't get 2 or more of the remaining geos in the green.
I'm definitely open to any feedback or suggestions anyone might have.

Another Follow-Up,
I managed to have my first $XX day in revenue (not profit). All thanks to nearly 200% ROI on UAE for the entire day.
I fought with Columbia for a long time, though I couldn't quite get it to work. I feel like there was a very narrow profit margin and the traffic volume just isn't there to warrant pushing it any more. It'd probably be a really good setup for a bot though.
All in all, I'd consider this a win and I think I'm ready to move on to the 40-day tutorial next.

I've been digging through yesterday's AE data and it seems there are some conversions worth 2 times the amount of others. What's the best way to go about finding the reason why, or is it just a random occurrence?
If I'm able to identify the source of those conversions and maximize my efforts there I could significantly increase my ROI even more.

Thanks for the insight @ranrev.
I'm on day 4 of my start to affiliate marketing so I have yet to buy a tracker. For the time being, I think I'm just going to be thankful I made my money back lol.
Next step, on to the 40-day tutorial!
Hi @lloric! Sorry for replying a couple days late!
The limit on traffic volume is very real on a source like PopAds, which doesn't have a lot of volume in the first place for the number of advertisers that are on it. Yes your targeting plays a role in limiting the traffic. The bid is another major factor. Frequency is a third factor.
Did you get around to cutting placement sites? That and testing bids are the main two things to do.
And yes the 40-day tutorial is the natural next step, after the $1 guide. I'm trying to find time to finish the 2021 version, but in the meantime you can use the 2019 version (but for the lesson on how to set up hosting and CDN, please use the one from 2021).
Amy
Thanks Amy I appreciate your feedback!
