There's a reason why most blogs don't make any money and part of the problem is due to the people who offer their advice on how to become successful at Internet Marketing.
How many times do you see people saying that blogs are so great at getting traffic that all you need to do is create one and the traffic will start to flow? It's these false statements that hinder others chances of becoming successful online.
The real secrets to making money with blogging have little to do with the blog itself.
It is the market research and keyword research that will determine whether your blog has any potential to make money.
This happens well before the first post is ever made on your blog.
And then there is another vital factor that will determine whether your blog makes any money and that happens after the blog posts have started.
It is in the promotion of the blog that you will get the opportunity to get ranked in the search engines and other places on the 'Net and until people know where to find your blog you won't get any income coming from it.
You need to understand that a blog is simply a place to hold content so that you have an opportunity to present information to the traffic you can attract to the blog.
That information should be intended to create a process that will lead to an income for you.
Blogs are popular because they are a fast way to get that content online in a format that is very search engine friendly and they also allow you to promote that content a lot easier than most other forms of content presentation.
It still takes the correct research in the first place and the correct promotion in the end.
