Hi Shirley,
Welcome, and happy new year. From what you posted, you are already well on your way to a prosperous online marketing campaign. Keep heading in that direction and once you get these 2 mastered, you can expand from there and get more detailed.
I have read every post in this thread and found that there are people doing the basics on everything, or one thing. I have to admit that
SEO has been my moneymaker for many years, but what most do not understand is that all of the methods (except PPC) is
SEO to a certain degree.
I guess what I am getting at is to become an expert in one or two fields at a time and keep expanding so that you continue to grow your business.
Like a car without wheels is worthless, so is online marketing without 2.0,
seo, article marketing and all of the other skills mentioned.
