Sometimes click to sale data can look like the profile of a mountain range. I know it gets annoying and seems utterly unfathomable on occassions.
Even partners delivering thousands of daily clicks see fluctuations in their effectiveness.
It would be great if you could just plug the traffic into a formula and get the results out of the other side. Unfortunately it is never like this.
As far as I
am concerned, a big factor is the relevancy of the traffic. Many visitors click, with little intent to purchase.
Our partners with the highest conversion rates are picking up highly interested and targeted traffic with a probable intent to purchase. They are using relevant content, combinations of text links, effective deeplinking etc.
For Jamster I can certainly advise what is working best in terms of creatives and content. Drop me a line if I can help in any way.
