The following is what I have noted from Big Data:
1) Big Data cannot be scalable nor practical if done by people. There is a rise in data scientists but they are not the real important parts. The real important area comes from algorithms that break down the data into easier to understand patterns.
2) It is recommendable to investigate into many of the rising (if not large) data analysis companies. This might make it more plausible for a small to medium sized company, like us, to actually be able to employ big data.
3) Content marketing through big data can be done in a variety of ways. It seems though that the common things may be things like following:
a) Keyword progressions
b) Universal search standing
c) Local SEO
d) Social SEO
e) Mobile SEO (don't really know much what this means... anyone?)
f) Global SEO
g) SEO ROI
As far as viral marketing/content marketing, these may be some of the basics of the data that we need to track in order to apply big data mentality. Of course, there is a lot I am missing, but still lol.
4) This may not be plausible, unless we create an idea of what data we want, the reasoning behind it, and how we can apply it.
