That's a good point Skitz but as you said "targeted traffic". That is marketing pure and simple.
And the way you do that is with onpage (Design & Programming) factors, quality content (English, Creative Writing, Technical Writing, News Reporting, Communications, Programming), and backlinks (Personal Networking, Communications) and all of it is done on a computer (IT, CIS). You probably (hopefully!) do some billing (Accounting). No matter what hat you wear Ethics come in to play. And if you are independant you also have to spread the word about your own services (Business, Marketing) and keep yourself afloat (Business, Accounting, Law). And all of that is under "strict"
SEO.
