When you have a limited budget, you'd want as much as possible maximum return on every dime spent. I questioned the return of investment of Article Marketing here.
Where should the main focus be when spending money? Paid traffic? Solo ads? Guest blogging? And which ones should probably not on the priority list? MSN, link services, scrapebox?
Need your thoughts. Obviously, it would depend on one's end goal, marketing, product, is one building a list, selling info product, selling a service, etc. But I'm looking for a more general advice. (i.e. Article Marketing is not a priority today, but a major focus in the past.)
