Hi Mr App! Nice progress!
You sound like a really logical thinker and it looks like you know what you're doing so I'll keep my comments brief:
-It would definitely a good idea to try shorter copy - the landers are pretty heavy on text. Most people are impatient and don't like to read. Long copy has its place but for antivirus, definitely test shorter copy as well.
-Testing other offers would be a really good thing to do! Use your best lander (or what you FEEL is your best lander - even if statistical significance hasn't been reached) to test offers. This way you minimize your test spend. Ask all your AMs for the best offers in your geo. You're with F5 already - others to include would be Adsimilis and Mundo (at least include these two). Those networks are strong for sweeps.
-Be sure to use a CDN and tweak your landers to minimize load times. That's one of the most major factors that influence conversion rate, so I'd spend some time on that at the very start. 
Looking forward to your next update! 
Amy
Thank you for the kind words, vortex.
- I'll definitely test short vs. long copy and post here the results
- At the moment I have VPS server hosted in EU. Will setup CDN next week.
Landing pages I think are pretty tweaked.
1) I have only one request on server. CSS/JS is minified and in .html file.
2) Every image is optimized with TinyPng
3) Images are embedded with XHTML - base64 image
Am I missing something important regarding to minimize load time besides CDN. By the way, which CDN provider do you recommend?
I'm using AWS (amazon) and that seems to work pretty well! Although more technically-inclined people may suggest more advanced options. 
A really useful tool to use to minimize load times would be GTmetrix:

And of course all the tweaks you've already done are great as well!

Umm, I don't get a scare feeling from those lps. Be as aggressive as much as you can or allowed to if you aren't cloaking. Fake scans, entry alerts, device vibration etc. Mimic the OS of the targeted phones, whether is android or ios. The virus angle works great with those.
Yeah much better. Split this lander in and see how it does.
Hey! I'm Polish and I have some tips for you:
- the language on your first 4 landers is quite unnatural and you have a typo on the first one ("naryzyko" - should be "na ryzyko"). I mean the language is correct, but the choice of words is bad in some cases.
- don't bother with nk.pl theme lol, it was popular like 7 years ago and it literally died out long time ago. People don't even remember how it looked like.
- the last lander you showed has some potential if translated well 
Good luck!
Great tips from pain2k and meakess! I just want to add one thing: Check to see if your offer requires lander approval or not. If it does, be sure to ask your AM how "scary" you can make your landers, or try promoting another offer that doesn't require lander approval. Also, not every traffic source will allow scary landers like your last one, so be prepared to have your lander rejected by some traffic sources. But you're definitely on the right track with that last lander!

The voiceover idea is great! To add audio to lander try this:
http://stmforum.com/forum/showthread...-mobile-lander
In addition to voiceovers - also consider testing other sound effects (think along the lines of system warning sounds
)
I wouldn't even start testing LP variations at this stage unless they are very significant variations (e.g. different angles, headlines, images...). If you do more spying you'll noticed there are quite a few different landers out there that look pretty badass. It would be better to rip those and mod them and test them first to see which style converts the best, and THEN test variations of them to further increase conversion rate.
Regarding budget - it's simple really - the more you spend the faster you collect data, but to speed up the testing you'd probably need to increase your bid which will make your testing more expensive than it needs to be. That's a personal choice only you can make. 
And yes - getting stuff translated properly is very important! You're spending all that money testing landers - don't stinge on the $5 required to get manual translations from Fiverr. If you don't have a lot of text, OneHourTranslation won't break the bank either.
Nice progress! Will be looking out for your next update....
Amy
ssmarketers, thank you for your observation. I've edited my previous post. 
One more vote for Fiverr than, great. I'll try with Fiverr with next translation.

Day 6 stats
Conversions: 5
Revenue: $21.15
Cost: $78.22
Profit: $-57.07
ROI: -72.96%
Yesterday I'd cut almost all landers so at the moment I'm rotating only 2. Today I'll create 3-5 new landers, aggressive as much as I can.
Yesterday Recap
- I found overall profitable carrier. Almost 50% of all conversions I got are from one carrier. (AM confirm that this carrier perform the best)
- Killed most of the landers with statistical significance
- Found Polish translator from Fiverr
- Found some aggressive landers for the same offer and placements that I got conversions from
Next steps
- create 3-5 new different landing pages for split-test
- create separate campaign on ZP targeting only the profitable carrier (they add this option yesterday)
- I'll check on popads/popcash if I can target specific carrier and try to get more traffic from.
Mr App, $4.23 per lead is pretty low for PL antivirus offer. I can see payout up to $6 in same market. There are offers with single click flow on higher android version.
ramgunjal can you tell me on which networks did you saw $5+? I'm in ClickDealer/Mundo/F5 media and I did not saw AV offer with $5+ payout.
pins perform differently for different carriers, and for some reason its not always the same on different traffic sources... maybe you can test that out
xavierfok you're right. I found out that I'm profitable on two carriers. Now I've created campaign on Popads and target both profitable carriers. I already start seeing conversions but still need more data. Thanks for advice!
Hi Mr App!
Thanks for sharing your optimizations and results so far with the STM community. Have you heard that we currently have a Case Study Giveaway? We are offering $1000 credit and an ASE pass to the user who will provide the best case study. Details are here https://zeropark.com/contest/. If you have any questions, feel free to contact toni@zeropark.com or support@zeropark.com.
It's always nice when you flip from paying for data -> free data.
Looking forward to seeing you scale it up!
Woot woot! (Breaking out the champagne...)
Here's to many more green days! Way to go!! 
Amy
Congrats that first green day is one of the best. Savor the moment! Keep going
Congrats Mr. App looks like you are on the right track.
getting to the green is the goal, but as i see it the journey is as important as reaching your goal.
your case study shows that not all the time (most of the time) you wont get that green on the first day and not even on the second or third.
but with a good campaign and with a steady process of optimization you will get that green eventually.
Keep up the good work and looking forward to see more success story's from you 
Day 11 stats
Conversions: 6
Revenue: $25.38
Cost: $10.67
Profit: $14.71
ROI: 137.96%
I'm still profitable, but only with one carrier - that's the reason why my ad spend is so low. I can't buy more traffic from specific carrier on ZP. I've put some deposit on Popads and create campaign targeting only profitable carrier but with #1 bid I can't get more that 1500 impressions.
Now I'm doing new landers based on current winners and looking for other PPV traffic source with carrier targeting options. Today I'm having problems because MundoMedia is not all sending conversion to
Question
What to do if campaign is profitable only on one carrier?
I've in mind two only things:
- find more traffic sources with this particular carrier
- do more split tests with offers/landers and try to get profitable on more carrier and then try to scale-up.
What's your opinion?
Thank you! 
Which GEO is that? It seems like a really small country.
Definitely try looking up in other TS. Also test second profitable carrier again tweaking. How are stats on it?
That makes sense.
Is there any option to find out if specific carrier support ISP billing?
I'll ask AM if she maybe know. I guest that it would be great to know for all carriers that don't allow ISP billing so I can exclude them from targeting.
By the way try adding phone callouts, for example : Your Samsung s10 was infected. This might increase your roi.
Nice work Mr App!
Great work on the follow-along. In particular, sharing your landers was a really good call - a lot of people are afraid to "out" their landers, but it's clear here that it allowed you to get quick, productive feedback. Nice work!
Looking forward to seeing your future updates. Don't get disheartened if you see a dip back into the red now and again - just keep plugging away and soon you'll be looking at serious profits.
There's one more thing I forgot to mention and I believe than newbies like me can found really useful.
Write detailed campaign diary every day. Don't write only one or two sentence. Write as much as possible.
In the last two weeks I've done a lot mini-modification in campaign (e.g. frequency cap, kill placements, adjust bid on placement or campaign, whitelist campaign, split-tests, adult/non-adult ...) and my campaign diary is really weak. I'll do my best to fix this in next campaign because I see now how important it is. My consolation is that it take some to build a new habit like writing everything down when doing on affiliate campaign. 
It may sound very simple but probably your advertiser/network is taking a huge margin. Based out of my own experience with the PL offers we're running in Addiliate.com, I'm sure your advertiser/network can afford 10$ per conversion. That will put you in the green (or at least very close to it) if you keep on optimizing the campaign further
cbrughmans thanks for this information. But I assume that I can't get payout bump because I'm still doing low-volume (avg. 10 conversion / day). I've sing-up in addiliate.com too see if you've any antivirus PL offers with higher payout. 
Great case study!
Don't wanna sound like a prick but I could tell from your first post I KNEW you'd get into the green pretty quickly 
Nice follow-along! Enjoyed your progress!
I've noticed you embed images through data URIs base64. This is not the best idea especially for mobile LPs.
Even if you save some HTTP requests you add way more troubles with it. If you only use it for small UI elements(~1kb) than it's fine, but for others larger images you'd better use CSS sprites.
