Hi guys,
I've been running mobile adult on zeropark for a couple of weeks now.
Here's my overall stats:

Offer
Currently I have 18+ SOI $2.2 payout offer, it has 17% CVR by network stats.
As seen on the image above, my CVR is far lower - 4-5%. I hope it's just an issue of my LPs and not of traffic source, and there is room for improvement.
Source setup
I target ~70 porn and dating related keywords, but most traffic comes from top 10. These keywords are marked as "broad" in zeropark setup.
I have not optimized placements that yet.
Landing
I've tested ~10 different LP designs, the best have 10-12% CTR, still enough room for testing copy/images/popups etc.
What bothers me is that my own designs perform 5-10x worse than those I steal and modify.
Also rules LP tends to perform best no matter what I try to replace it with.
Based on what my AM said about rules LPs: "it shits for the adv on the backend, doesnt convert for them, they[publisher] get kicked off the offer" I should be trying further.
Also I've tested 2 geos - 2nd seems to have 2x bigger CTRs on the same page.
A few questions:
1) Should I test DOI offers or they don't work on mobile?
2) Is $2.2 payout enough to make campaign profitable? Considering my CPC (LP->offer clicks) probably won't ever be below $.15 even after all LP optimizations. (now it's ~$.22)
3) Should I care too much about replacing rules LP?
Thanks for reading 
1) doi also works but are these wap offers.
2) 2.2 is good payout for mobile. You need to get cpc below 10 cents and close to 1or 2 cents.
3) rules lp have worked for me.
Your best CVR is 0.32. I think you would be talking about offer CR. Usually its 8 to 20% and CVR from 2 to 4 %.
You need to improve both your banners as well as landing page. Lp ctr should be around 30 to 50%.
miteshmuley, it's zero click traffic, so there's no banners. So, "Visits" stand for landing page visits.
Probably I've messed up with terminology a bit here, I meant LP -> offer clicks.
I think both the landing page CTR and backend offer CVR are really lacking here considering your cost per view.
$0.02 is a normal CPV/CPC for adult mobile.
0.15-0.3% CVR is not.
How many targets have you killed off? Surely there are some that are doing much better than these averages?
There's a reason the rules landers work well. If you make new landers, make sure to think about your ad copy and the psychology involved, i.e. WHY do the rules landers work so well and how can I emulate that?
Anyway:
1. Lander CTR too low. Cull targets. Test other landers.
2. Split test offers on the backend. 1 in 25 clicks to the offer converting is bad.
3. Consider adding e.g. exit pops (split test this with a different lander!) to skim off some conversions.
One thing that has worked well for me in the past when creating new lander styles is to look at successful landers from other industries.
For example, at one point I used a magazine ad from the '60s - a David Ogilvie ad, as I recall - as the basis for a successful dating lander.
Try looking at startup landing pages, or loans landers, or sweepstake landers, or even direct-response newspaper ads - that you know work - and see if you can transpose the techniques there across to adult, then test that.
It won't always work - but it sometimes will.
I've disabled 6 worst performing placements today:

Also there are two distinctly winning placements with nice amount of traffic available there, but average bid is 1.5x higher than mine. Should I create separate campaign for them with higher bids?
Btw, I forgot to mention that I already switched to android only, as IOS was clearly losing with 10x times fewer conversions.
Yes - on ZeroPark much like with other traffic sources, when you find working placements you should make a new campaign and hit those with the intent of dominating the traffic. If it's profitable, you want it!
In ZeroPark you do this using a target campaign.
Here's my stats for the past 2 days:

I've fixed some css/layout issues on my main LP. Now the text is bigger and overall more readable. I don't know if it's a just a coincidence, but now I have lower CTR(now 7%, used to be 10-12% for this page) and higher CR.
Today I'm going to add exit popups with webcam offer links.
Also my daily budget at zeropark is set at $20, but it spends only $10. Placement report shows there is much more traffic available. I don't know is the bid too low or day parting algorithm is fucked up, will try tuning both.
Probably a low bid.
Hey guys, a quick question - what is just "chrome" browser on android? (green frame)

Also lol @ someone already stealing my page.
Possibly people on Tablets who have full Chrome installed? Or maybe devices like netbooks that have been incorrectly detected as 'mobile devices'?
Try drilling down from Browser > OS > Browser version etc. to see if that offers any insight.
Thanks, zeno, I did not know of that
Here's my stats for the past 3 days:

You can see CRs varying wildly. Pretty nice result today though!
I've been testing new LP layouts, some are obviously not very successful, so overall CTR is bad. Still I can't get over 10-12%.
I was trying to make exit popups work properly. My plan was to replace standard browser exit popup with some text and images. After 3 days I understood that modifying is limited to text only. Now I'm displaying standard popup with replaced text. It asks user if he's not into dating today and offers some webcam girls. If user agrees not to leave, I show him modified popup with text and pics which direct links to webcam offer. So far only ~1/100 agreed lol
Also I've added new geo with the same offer. It contributed quite well. But still IOS users convert much worse than android. That's sad, cause IOS traffic is cheaper and there are 2.5x more ios users than android. Can red WOT score of my offer be a problem here& Probably gonna test IOS with some more offers now.
How are those stats varying on a placement-to-placement basis? By now I'd expect some no-hoper placements to have bubbled up if you're not already actively cutting them.
caurmen, I've posted a screenshot of the placements I have cut on the first page (post #6). I've added a couple since then to the list based on 2-3x payout spent with no conversions. Now it seems I have no major placements left. 90% my converted targets have like 10 visits and 2000% ROI for last 7 days.
Have you moved your converting targets into a target campaign?
If you haven't yet, do this so that you can increase your bids on individual targets to try and get more of the available traffic. Then, keep adding keywords to your KW campaign in search of more targets.
I should have also added that your bid looks pretty low. Increasing your bid won't just give you more volume but it should give you a better look in at the more competitive/higher quality targets.
The thing to remember about target campaigns is that other people are using them. That means the best targets have much higher bids attached to them and at a very low bid you may just be getting a lot of left overs.
If you're on a tight budget, try increasing your bid on your most productive keywords first and see what happens. Hopefully it brings some new and better targets out of hiding.
First of all I want to thank Robert (and the rest of zeropark team) for their help! They're all very nice and pleasant to work with 
pawly, I created a separate campaign where I put placements with positive ROI.
My bid was ~1.5x higher than in the main campaign.
Got 320 visits, 1 conversion, $11 spent, -80% ROI. Probably need more data.
Also I have yet to test higher bids on my main campaign.
My webcams popup kind of failed, almost no one clicked it and added page size increased load time. So now I use just simple popup that's asking the user to return and look once again.
Until now I've focused mainly on testing LP layout(with a couple of wide angles); it seems I figured one, which gives stable good CTR.
Now I'm going to test more different angles. I outlined ~10 narrower angles to create a separate copy for each one. I'm going to limit it to 50-70 words to make mobile a bit less crowded with data.
I don't know if it would be better to test all of these angles head-on, or lure users with a sweepstakes offer to make them pass a dating-related quiz. Something like what they don't like in existing dating sites or what would they expect from the ideal one. I think I have seen this idea somewhere on the forum, but related to antivirus installs.
By the way, can someone explain me the following:

It's from the network that owns the offer.
They say it is a "Pay Per Lead Program", but still the payout depends on how many users get paid subscription. With 2-3% expected conversions... What if I make 200 leads and no one subscribes? They won't pay anything? What's the difference from the PPS program (€91.85 payout) then?
PPS will be that you get paid a decent chunk when someone converts.
The lead-based program you're probably in now will pay for each lead but will increase the payout per lead as your backend quality, judged by %conversion to paid users, increases.
Think of it as a defined set of payout bumps when your backend quality is decent.
If your quality and backend conversion rate is high enough, it may make sense to move to PPS.
However, the tiered pay-per-lead is a better starting point and probably works better for the advertiser if your leads are good (sneaky sneaky).
I'm not sure what the 1000-1000-1000 lead stuff means, maybe they expect 1000 leads before they bump you each time.
So guys, it's been a week since I last posted my stats. Here they are:
5.20 - 5.27
Main android campaign:

Test ios campaign: I took my best landing and optimized it for ios browser as much as I could, for both phones and tablets. Also thrown in a few offer landers. Still does not work.

I was continuously cutting bad placements. But it seems it's not enough. So here I just stopped ~25 worst placements even if they did not have enough data to be statistically significant. Also I increased the bid almost 2x so that I'm top bidder for the geo.

The quality(CTR/CR) seems unchanged.

And now I'm a little lost.
Here's what I tried already:
Page layouts: 3-click yes-no page, 4x rules pages, map, 5-6 image+benefits pages, 2x fake chat pages, a couple of pages that mimic offer page
Angles: local girls, get attention, largest site, cheap dating, safe-to have an affair dating, pick up girls fast/easy, pick up milfs/ugly girls/elite girls/ex gfs.
And also many smaller points from the cheat sheet provided to us through the courtesy of mr.Finch 
Don't know what else can I test. Maybe the angles are not creative/agressive enough?
</emo mode>
So, here's the last thing on my mind.
Most of my keywords are porn-related. All with negative profits.
But there's a group of dating-related keywords that have positive results. Probably it's 1/7 of my traffic and it could give me maybe 2-3$/day.
Should I focus on these keywords and try to scale it to other countries/similar sources? Or just pick another vertical/source/what else?...
If you have profitable keywords in their don't ignore them! Find their targets and create a target campaign for them.
If you have already made landers and have data then you've done the legwork - no point in leaving profit on the table if you can set up the campaign quickly. $5/day isn't much but if you manage to do that and find more keywords, roll out to several countries, you may have a set of campaigns that trickle in $20 profit daily for weeks to months.
Thanks, zeno. I'll try running traffic to these keywords for a few days and then we'll see how it goes.
Remind me again - how many offers have you tested on this one?
caurmen, I've tested mainly hookup, blackbook, getnaughty + a few clicks to AFF, xdating, shagaholic
Hmm - are you just testing one angle or multiple angles?
It feels to me like this is probably a campaign that you'd be better cutting your losses on, assuming that Zeno's suggestions don't see you into the black. You've got a lot of knowledge of running a campaign on ZP now - I'd start some new ones with the best-performing offer and new angles and see if you can beat your initial results.
Just FYI, I don't think there is enough traffic on this platform for mobile adult and the ROI will be like -20% to +20% on any given day. I wasted a lot of time with it. At the end of the day though there is not that much traffic.
It was US.. I was thinking about it and decided I needed to come back and clarify: where I needed to bid there was not enough traffic to warrant spending more time on the campaign ($.015-.02 range)
