My first POF campaign - Results!

So having read a WSO and the whole of Mr Greens website, i decided to have a little go at promoted a CPA offer.

Below are the results, and then I would like your opinons on how to improve and some answeres on a few questions I have.

I ran a campaign targeting US traffic, female and broke it down to 3 age groups = 20-30, 31-40, 41-50. They had to have blue eyes (as this was my angle).

Age 20-30

Total spend = $8.61
Impressions delivered = 28,663
Clicks = 15
CTR = 0.052%
CPC = $0.57

Age 31-40

Total spend = $7.99
Impressions delivered = 26,303
Clicks = 14
CTR = 0.053%
CPC = $0.57

Age 41-50

Total spend = $7.91
Impressions delivered = 25.614
Clicks = 18
CTR = 0.070%
CPC = $0.44

The offer which I promoted was the Free Ugg Boots over on Peerfly.

Out of the 47 clicks I had, only 3 converted. I was direct linking and not using my own LP.

Now the issue is.. I dont know which clicks actually converted. I put the subid into the Peerfly URL it went from:

http://peerfly.com/x/0/3469/62563/
to
http://peerfly.com/x/0/3469/62563/a1/

with 'a1' being the subid but when I check my peerfly earnings report it shows the referer as being ----

How do I go about setting up the subid correctly?

I split test 7 different images and then mid-campaign I deleted the worst preforming images so now each age range now has the 2 best preforming images.

This is my ad copy:

Do you have blue eyes?
To celebrate International 'Blue Eyes Day' Ugg are giving 1000 lucky blue eyed beauties a free pair of Ugg Boots. Claim yours!

What can I do to improve this? Is the offer not converting and would it be more benificial for me to change the offer to get more converstions from my 47 clicks or is 3 what I can expect from an email submit?

Any comments would be much appreciated.
