Hi,
I tried to search the answer on the forum, but I didn't find.
I'm running a campaign on my own traffic source since the start of the month, I think I now have enough data to cut some offers, ads and landers, and to create new ads and landers from the winning ones.
But I really don't know how to choose which ones to cut, and which ones to keep, I'm using
Some people told me to focus on EPC, and others only on EPV...
But sometimes the EPV is high, but the landing page CTR very low, so the result is low conversions compared to others LPs.
So what should I look at before cutting anything ? (Ads CTR from the Adserver ? Visits ? Clicks ? Conversions ? Landing page CTR ? CR ? CV ? EPV ? EPC ?)
For offers ?

For ads ?

For landing pages ?

Sorry for all these newbie questions, but I'm really blocked on this step.
Thanks in advance for your help. 
For the landers I think this awesome post by Amy is perfect : http://stmforum.com/forum/showthread...Banners-Part-1
But for the ads and for the offers, if you have tips, don't hesitate to share. 
Thanks.
Since its your own traffic and as such its virtually free, all you need to figure out is what gives you the biggest revenue. All the other factors are irrelevant - you dont have to worry about bids, CTRs, bots etc.
The only criteria here is to make sure all ads in a particular spot have been running for the same period of time before making a decision.
First figure out what landers work the best and reduce the number to 2-3 - Look out for specific ad+LP combinations, sometimes some banners work much better with one LP over the other one. 3 of your landers show lower performance, the rest is pretty much even, so you will need more data there ... or maybe the deeper banner/LP/offer analysis will show you what to focus on.
Next are the offers, cut the worst ones first. I see big differences in revenue for the various offers, no idea whether its because of uneven distribution or some are newer than others ... only you know which ones work better.
Whatever you decide to cut in this case, keep in mind the only relevant factor for you is TIME and REVENUE. So what banner/LP/offer made you the most REVENUE in a day/week ...
EPV, EPC, banner CTR and what not are not really that important when running ads on your own site.
Thanks a lot for your answer Matuloo. 
I'll look at the eCPM for the banners, and at the EPC for the offers.
I think the optimization is really the hard part, I need to figure out how to use the data efficiently.

Ah, I just search and sometimes they talk about the cost, sometimes about the earning.
The formula is :
