Consistency in blogging has always been a founding key to creating a cash cow blogging business.
From all the bloggers I know who are making predictable incomes from blogging - one thing that keeps coming up is this: They all blog consistently and they consistently focus on a niche.
In other words, they definitely don't take the casual approach to blog only when they want to.
If they blogged once a week, they kept that consistency.
If they started by blogging every day, they kept that rhythm going.
Why? That consistency is for their readers' sake.
Nothing turns off your readers than turning up and finding out they can't rely on you turning up at your blog.
So turn up regularly and consistently and show your readers that they can rely on your consistency.
Find your rhythm and stay on it.
Your readers love and expect consistency from you - they depend on it.
Now regarding niche focus; the best and successful bloggers tell me that they are better recognized when they focus on a narrow niche topic specialty.
By staying on one niche your readers see you as an > in your topic and know that they can rely on your consistency of information.
If you wrote on a wide range of topics your readers may find it hard to keep track with your information and may be more prompt to lose patience and leave your blog than stay.
The money in your blog will grow out of your ability to stay consistent.
