Hello,
I've always been wondering about this fact.
Case 1 :
I get an offer from X Affiliate, send traffic to it, gets around 100 click to offer on it, No conversions (or some, but the ROI is terrible).
Case 2 :
I get the same offer from Y Affiliate, send traffic to it, gets around 100 click to offer on it, gets enough conversions to keep running this offer for a while, and still performing good.
Both offers are equally rebroked, or both affiliates are getting it from same advertiser. The idea is that they're the same, just different Affiliate Network.
Is shaving the only reason here? I'm frustrated about what could be the reason if it's not shaving.
Do they use the same platform, like Cake or HasOffers.
It could also be their backend is very different, because 100 clicks is not a big amount of traffic so it could make a difference.
Scrubbing can certainly be involved too though.
Yes, both are using same platform. But in case they're using different platforms, why would that change anything on the conversion side ?
Statistically, from my previous data, 100 clicks should get me at least 1 conversion. I'm running nutra offers and my assets are quite stable for now. But there again, nothing is never stable with AM...
If 100 click is not enough to stop an offer, then what do you think would be the appropriate time to stop it?
Well, it's not only about exact clicks, but also about how much those clicks cost 
The conversion rate can vary because of redirect speed and stability. If when someone clicks on your ad to get to the offer page, they go through the networks backend tracking, and if that is a bad redirect (or just worse) you get a different conversion rate. That's another reason rebrokered offers most often do worse, not just the lower payouts.
I am not sure which is more likely for your situation - you can find out by telling the network doing worse that you will stop 100% of traffic because a competing network is converting much better. That sometimes fixes it if it's the scrubbing that's the issue.
If you really think it's scrubbing, I would think of ways of opening the conversation about it but not in a "blame game" type way - almost universally, an affiliate network would not scrub affiliates for no reason. You have to find out the reason, and see the logic behind it.
For example, there's 1-2 "bad apples" that scrub for marketing purposes, to afford higher payouts. If some networks then don't do that, they get fewer new affiliates to run with them so their hands are tied, and have to play the scrub game. It's also sometimes a way to adjust margins for lower quality leads instead of kicking/pausing/adjusting payout.
You should generally have a big selection of networks nowadays anyway - I'm just mentioning this about scrubbing because it's often said that you should not work with a network that scrubs you, which is something I disagree with. I think you shouldn't work with networks that outright scam you, but the scrubbing dynamic is much more complicated and it's useful to understand it a bit.
I'm on Native, so the Clicks costs are somehow high comparing to other traffic types I think. I will start checking the redirect speed from now on, it's a good idea indeed.
And Yes, good point on how to open the conversation when getting scrubbed 
Thanks for the tips!
So a few things could be going on here
1. The tracking could not be working on network 1. Just tell your AM to look in the backend as you've run the campaign other places and it seems to be converting better. 0 sales often = tracking issue.
2. For statistical relevance you need a lot more clicks potentially. Maybe you got lucky on the first clicks from the second network. It happens.
Yea probably shaving. Especially if its a cake network, shaving is a built in feature there.
There are many reasons for this, some have been mentioned already : scrubbing, tech problems ...
The 100 clicks you mentioned - was that an example or a real number? You can't really judge anything after 100 clicks, especially with higher payout leads - it's absolutely normal to see erratic conversions with a low amount of clicks. You can get a random lead or two anytime and that would completely change the results of the test.
One way or another, networks are not equal, that's why we always recommend to test a few and stick to those that you like working with.
- Advertisers also use various scrubbing levels - they see better results for traffic that they are getting from some networks, so they scrub them less. So working with better quality networks can benefit you in the long run.
- Some networks can have custom built pre-landers, that can obviously impact the CVR a lot.
- The tech setup of the network plays a role too, in case they are using custom tracking domains or some extra redirect on top of what Cake does ... that can influence loading times too.
It can also be a total coincidence, you simply sent worse traffic to network X than you did to network Y... even with a properly setup split test, you need to send a lot of traffic to reach comparable quality of the traffic mix. This can be quite complicated with BOT heavy sources at times ...
Thanks all for your answers, helps me understand how this works!
100 clicks are real number actually, it's just the my epc is normally high enough to get a conversion at 50 clicks maximum, so 100 clicks are double of what I expect. But you guys are right, that is not enough click to judge an offer...
