I am baffled.
I looked at the Nuffnang ad units for my blog, and the earning, I have no idea how it works.
First, they said it depends on viewers traffic. I am getting more traffic flow into my blog, not by big count, but the earning I got was actually down by 25% while my traffic increased by around 4%. So does it mean that the more traffic you get, the less you earn? Damn, that girl whom called herself xiasui xia xue must be earning pennies right now. And poor Kenny Sia, he must be owing Nuffnang loads of money now.
By the way, there are periods that I don’t get paid. Take a look at the picture below.

Notice the breaks in between December and January? There are 2 weeks when there’s no income. Nothing at all. Well, the last time I checked, my blog was still serving advertisement from Nuffnang during that 2 weeks period. Does that mean I am serving these ads for free?
Or does it mean that Nuffnang tracks the traffic and only those originated from Malaysia and Singapore counts for the ads earning pay out? I have no idea.
No, I am not trying to bitch on Nuffnang. I just hope someone can explain to me how it works, and why I am not getting any paid out during that 2 weeks period. Besides, my ads earnings are so measly that it doesn’t make a slight difference to me, but I just want to understand how it works and I just need an honest explanation.
So anyone can explain to me how it works?

Let me clarify about my confusion.
If you were to dig through Nuffnang FAQ section, you will see this…
a) Cost Per Unique Visitor Ads
Earnings for Cost Per Unique Visitor Ads are calculated based on the number of unique visitors to a blog when an ad campaign is being run. Basically, you have to achieve a minimum amount of 20 unique visitors to your blog and maintain that amount in order to be in the running to receive Cost Per Unique Visitor Ads. Then, you can sit back and relax while our advertisers select the blogs on which to run their ad campaigns on. Should you be selected, you will be notified by email based on the type and the duration of the ad campaign.
b) CPC Ads
Any blogger registered with Nuffnang is automatically eligible run have CPC Ads. You will be paid each time the ad is clicked on and your earnings will appear at the end of the week.
In spite of running CPC ads, Cost Per Unique Visitor ads will always be given priority since in the past we have found that that Cost Per Unique Visitor ads seem to pay more since they don’t depend on the number of times your user clicks on your ads.
The amount of earnings along with its rates will remain confidential until it is released in your earnings.
It is clearly stated that once you have a minimum of 20 unique visitors, you will be able to enjoy CPM or CPA ads, which pays a better rate. Now, the problem is, I have more than 20 unique visitors per day, and yet my ads are still in CPC format. So how does that happen?

the CPC stands for “Cost Per Click” and how much you earn depends on how many clicks it received. if it had no clicks, it generate no income.
also, global CPC ads does not discriminate clicks in different geolocation. a click is a click. and u’ll get paid if u get any
Oh, i’m not from nuffnang btw. just happened to see this post and tot i’d help a fellow blogger
You are getting just CPC ads..not CPA or CPM ones..
if CPM or CPA ones..then, that will in itself make you earn better, depends on yr PR,ALEXA and trafic conversion.
I did do a write up on one of my blogs the other day about this. A CPC now is about 20 sen

The guys are right, you know. It’s cos it’s CPC. If nobody clicked on those ads during that time period, you don’t get paid for it though it’s featured on your page. That’s the way the system of CPC goes.
If you wanna be sure that you’ll earn, check for emails by Nuffnang. They’ll inform you when you’ve got ads coming up. If you got those emails, most prob they’re CPM ads. Then, even if nobody clicks on them, you’ll see moolah comin in.
Cheers.
p/s: I’m not working for Nuffnang either. Just wanted to help you out with your confusion. =)
Thanks guys/gals, the information you provided are really useful.
But the reason why I felt confuse was after digging throuogh the FAQ, here is what I found:-
a) Cost Per Unique Visitor Ads
Earnings for Cost Per Unique Visitor Ads are calculated based on the number of unique visitors to a blog when an ad campaign is being run. Basically, you have to achieve a minimum amount of 20 unique visitors to your blog and maintain that amount in order to be in the running to receive Cost Per Unique Visitor Ads.

The amount of earnings along with its rates will remain confidential until it is released in your earnings.
In point (a), it is clearly stated that once there are more than 20 unique visitors, the ad will be CPM Ads. My blog has more than 20 unique visitors per day, yet I am still in CPC?
Cost Per Unique visitor ads are “served”. Basically, you don’t have any of them till Nuffnang send you an email telling you that some are coming your way. Without notification, the ads you run are still CPC
Alright, seems like I will have to wait for Nuffnang to write me then…
Ok! I finally got an email from Nuffnang and they told me I have an advertiser going to advertise so I guess that Cost Per Unique visitor ads?
So please come back more often to help out a fellow blogger!
