What is your core?
For example my core would be SEO, I gain traffic to sites via SEO and ranking for them which continues to draw in tons of free traffic and convert it into sales on clickbank, cpa and amazon products.
While I do list building I would not consider it the core of my business because it only backs up if the sale was not made from the site itself.
Some core's that come to my head now are
SEO
List Building
Article Marketing
Back linking
Media buying
JV partners
and so on...
Would love to hear your take on this and what you have had success with thus far.
