The fastest way to the blog cemetery is to write a nondescript, vague blog that has no focus, no central theme, and no specific audience.
Once you have your main concept in place, the next most important step is to determine for whom you’re writing your content.
Before you answer, know that your answer can’t be “everybody.”
This is when you have to put on your marketing hat and think like a professional.
“Everybody” doesn’t love the television show Everybody Loves Raymond. Everybody doesn’t like Matt Lauer or enjoy Lancome cosmetics.
So everybody won’t enjoy your blog.
You need to figure how who will.
