In order to answer this question, you need to answer this question:
Why do you have a blog?
Believe it or not, many people have blogs because other people do. With click-and-publish technology, anyone can have a blog.
The oldest blogger I know of is 81 years old! She’s a real treasure. Hats off to her!
But why are you blogging? So that you can say: “Look, Ma! My own web site!” Or do you have a larger purpose? Figure that one out first. Once you know why you blog, it becomes much easier to explain why you need to know where your traffic comes from.
If you don’t know why, details about your traffic will be nothing more than a vanity factor.
If you know why, it’s gold in your hands, waiting to be converted into opportunity.
