It's not easy to make money from a blog but it's not impossible. One reason many fail to make any money is because they choose a saturated niche and if they aren't committed competition will see to it that they make no money.
I saw this on a forum and though I don't intend to use this method to make money maybe someone might find it helpful.
Here goes:
You'll start with some research. Find a micro-niche with little or no competition at all. Step #2, create a blog on blogger.
Do some keyword research and find all the long tail keywords you'd like to rank for and create a number of articles. This should get you a little traffic from search engines.
Once that is done, find blogs in that micro-niche and post a number of comments on those blogs. These will also draw some traffic to your site. You could also promote your blog on forums and social media networks.
Done? Place your affiliate offers on the site. And go create another. Rinse and repeat.
The author of the article claimed that after a little while you'll start making at least $1 a day passive income from each of your sites. So if in a year you can make $50 such sites, you could be making $50 a day. Not bad if you ask me.
