44. If you don't know who you are writing for, they won't know what you are talking about

This is probably the number one mistake of most bloggers: NOT knowing WHO they are writing for.

If you don't know WHO you are writing for, then you cannot possibly know WHAT they need from you. Therefore, you cannot possibly write a good blog, because no matter what you write, it will be irrelevant to their needs and priorities.

Here's an example:

Instead of writing a general blog called "Career Advice", you could write a more specific blog called "Career Advice for Career-Switching Baby Boomers."

The latter is more specific, and will guide you as you research and write high-quality content that is relevant to your audience.

Remember the adage in marketing: The more you segment the market, the more you augment the value.
