Pro Publishers! I need your Advice.

Hey All!

Dear PRO Publishers, please give me some insight.

What kind of offers are popular in Nordic countries? (Finland, Sweden, Denmark, Iceland)
What is really demanded?
Which affiliate network you use?
Is it worth starting publishing in such countries, some articles say that there is low competition but still lots of money…

What do you think? How do you work there??

P.S. Please feel free to PM me anytime)
