Niche Blog Advantage
It's Niche Blog Advantage by Jason Johns (obviously not an affiliate link ;-) )
I bought it for my son, who is new to Internet Marketing, but then I looked at it myself and found lots of little hints and tips that I didn't know. Not only is the content interesting and useful but the actual quality of the teaching is excellent.
This course hasn't had the hype of a lot of other courses out there but, for me, it's really as good as they get. Great value for money.
