Without a strong blog purpose, and a plan to fulfill that purpose, a blog soon dies and the blogger is bored or floundering without a path.
Set the Blog Subject Matter:
Blog Editorial Calendar:
Whose Blogging:
Blog Demographics:
Blog Goals:
Clarify Blog Purpose:
Once you have your plan and purpose defined, then the choices you make for promotion, monetization, and good practices will automatically follow suit. The clearer your purpose, the better choices you will make.
