Great post - I'm a bit late in seeing this it seems!I have a question around how you assess the metrics and in turn success of these websites. It's obvious where the money is coming in for most of them but Im wondering how you assess 50em.com? Its a great looking site but it has around 350-400 organic views a month and does not rank 1st, 2nd or 3rd for most keywords - not even its main target keyword -ontraport vs infusionsoft. Are you assuming its successful because of the high commission rates for these products and they might make 20 sales a month or is there other signs you see that indicate its a profitable site (or do you know the owner!)?
I loved seeing the example of the Kids Tablet with Wifi utilizing affiliate marketing. It gave me some great ideas on integrating amazon for my own children’s blog. I would be interested in knowing how much they are earning monthly from their affiliation. Being a mother of a two year old myself, I could see myself writing reviews on Amazon products my daughter enjoys.
