Hello Krissh Roy,
Welcome to the Paid Insider Forum. That seems to be the million dollar online question.
How can I make a real online income?
It is a question that is not easily answered without knowing your particular skill level, interests and abilities.
If you can write than I would say start with creating your own short reports. I have a free ebook that shows you exactly how to find profitable niches and target them with your own short reports for immediate income.

There are also sites like Associated Content or Constant Content that will pay you for any articles you create and submit to their sites. If you have any other internet skills like graphic design, help desk or script writing/installation you could submit your freelance rates on sites like Scriptlance, Elance or Rentacoder.
Now, if you are inexperienced in any of the above and lack the writing skills to create your own info-product I recommend you look into affiliate marketing.
Affiliate marketing will allow you to promote the products of others for a large commission. sites like Clickbank or Paydotcom list products you can promote for 50% or more commission for each sale. You can set up a free blog at Blogger or Wordpress to promote these programs.
Using Web 2.0 sites like Myspace, Squidoo, Hubpages or Youtube videos is a great way to funnel traffic to your blog. Once there you should attempt to capture the email address of your prospects before you send them to the affiliates sites. This way you will be building a long term business and have a database of potential customers to build a relationship and share your information with.
