The general rule of thumb here is: the more specific, the better. If you’re writing about how to make money blogging through advertising, “How to make money blogging through advertising,” or something along those lines is a far better title than simply, “How to make money blogging,” because by narrowing down your focus, you have a far more targeted pitch. And if you are writing about all the ways to make money blogging, try, “Everything you need to know about how to monetize your blog,” over, “How to monetize your blog,” because, again, “Everything there is to know” is a more targeted pitch than just, “Things to know.”
