Hi Paul,

Pleased to meet you.

I am not sure what you mean exactly.

Are you asking what topics you need to be studying to become an Internet Marketer?

Some of the most helpful skills and areas to gain knowledge for an IM (although you don't meed to possess all of these all yourself) are;

Researching to find potentially profitable niches
Keyword research
Traffic generation -for eg PPC, SEO, web 2.0 etc - my favorite topic
Product development
Copywriting
Conversion (selling) strategies
Affiliate marketing
Website creation

Cheers,

Anthony
