The most important rule to remember, when writing a money-making Blog, is this:
“Nobody cares what you had for lunch!”
Self indulgent, vanity publishing style blogging is not where the money lies ( unless your’re Britney or Paris). On the other hand if you are a good cook they might well be interested in what you cooked for lunch - either for yourself or clients!
Because the thing about blogs is that they allow people who like your content (aka posts) to ‘subscribe’ i.e. they’ll be notified when you add something new to the blog.
The other cool thing about blogs is that they are ( or can be) interactive. The visitor can leave comments and input. This is known as Web 2.0 ( getting people involved, in a nutshell). The trick is to find your niche and a subject you feel strongly enough about that you will add content to your blog(s) regularly and consistently
