Just for example, for a small whitelist camp.
Is it better to rotate say top 3 lander that are doing -10%, +20% and +50% for longevity until I am able to get more LPs that beat my top control.
OR
Run top lander +50% all the time and risk it burning out in a week?
I would suggest to run your +50% ROI top lander at all times and upscale it as hard as you can. Once you see performance going down (<20% ROI), you can start testing out other landers.
While you are upscaling you can always work on new landers so you don't lose any development time once performance is down. Eventually every campaign will die out so the trick is to make as much money as fast as possible.
Would this apply to my main campaign as well or continue split testing landers on main campaign.
Right now my setup is:
Main Campaign: Focuses on blacklisting placements and opening new placements at higher bids. Also for split testing landers to beat control.
Whitelist campaign: Full on pumping best lander.
Should it be run best lander on many different traffic sources to scale (Is this vertical or horizontal scaling?) and then test offers from other geos with best lander and a few ripped?
What I would suggest if you were to be one of our superaffiliates is to have a threeway campaign
1. Main campaign: use the winning lander (+50% ROI) and use the strategy you are using. Blocking bad placements and adding new ones at a fast pace
2. Whitelist campaign: Full power on the best lander
3. Test campaign: test new landers but excluding a) bad placements from Main campaign and b) blocking placements from Whitelist campaign. You don't want to bid on the same placements than your whitelist campaign as then you would be bidding against yourself
Hope this helps!
To offer an alternative perspective...
So you're running a profitable whitelist campaign/tight targeting/whatever. The traffic from those zones with that config is proven to work!
If anything this is a better time than ever to be testing new landers. Your data is going to be (arguably I guess, I'm no statistics PHD) more reliable compared to testing them on a RON campaign with a bunch of shitty zones - which you may not know are shitty yet - polluting your data.
This is the beauty of AM, what works for one person, doesnt really have to work for the next one
Thats why people willing to inovate, always find their way to make it in this biz.
According to my experience, a mix of the above mentioned two approaches would be the best.
First of all, there is no need to run a negative ROI LP when you have 2 other that give you positive ROI. Longevity is one thing, but you are not here to loose money either. On top of that, LPs usually last longer than banners for example, so their live cycle isnt so short.
The other 2 are at +20% and +50%, if it was like +50% and +40% or even 35%, I would say keep running both. But this is quite a difference so its not the best idea to keep running both - so Im with Christoph on this one.
However, Im a strong fan of using at least 2 LPs in rotation at all times, so I'd suggest trying to improve the performance of the +20% LP or make a variation of the +50% LP. Here is where Im gonna agree with Stich, I would use the whitelisted campaign for a few quick tests in an attempt to find at least one more useable LP that I could run along with the winning one.
A friendly tip at the end : When running campaigns with lets say 2 LPs, I always try to put one on a CDN and the second one on a VPS or dedicated server, or on two separate servers. This protects at least 50% of the funds against server downtime and helps you to quickly spot any problems with the host - when 1 LP works fine and the other one doesnt, you know where the problem is 
Thanks guys for the informative responses. I have changed my strategy to maximise current profit. So anytime I find one of my new LPs is doing really well. I will use spam that.
Also, I have set up this way now.
3 camps:
1) Main camp: Only blacklisting. Kept all whitelist targets. Testing higher bids to find balance between volume and profitability as well as finding new profitable placements. Running best LP here.
2) Whitelist Camp: For whitelist targets only. Running best LP here.
3) Lower bid camp: For testing new LPs, and some breakeven/slightly negative placements. Excluded all blacklist and whitelist targets.
My question is, would my main camp and whitelist camp end up bidding against each other?
PS: I am still figuring out my own system while incorporating all the advice given.
Yes, Main camp and Lower Bid camp end up bidding against each other but that is OK as you are using different LPs/creatives so you will see who the 'winner' vs 'loser' is.
Make sure to upscale and pump your Whitelist campaign as hard as you can as this is your moneymaker.
