Article writing can be a source of earning other than blogging. Earn money from blogging is not as easy as two years ago. If you are just starting your blogging experience, try not to put too much hope in earning three figures, four figures, five figures or six figures income monthly. Maybe, 3 figures are possible for early stage but more than that you need to spend a lot of time.
Besides blogging and building traffic to your site, you can participate in writing articles for money. You can check out the options at Scriplance, Elance and DigitalPoint Forum for opportunities available. Plus, you can really learn how to type fast, keyword usages, ideas, etc. Now, you can easily write about your advertiser on your blog in paid posts or offer writing services.
Even though, you don’t have anything to write today but you still want to write something. Addiction towards writing is also a side effect from writing article. Don’t worry about it. I’m sure you can sell those articles you write for money or post it on your blog.
