How to start earning online?

How do I earn online?
Is it worth the time we spend?
These are the most common and popular questions.There are many ways to start earning on internet through affiliate programs but one thing must be kept in mind that it requires hard work-(you will be happier if you do it) and time-(no fixed definition for this, but probably 30 minutes per day).
You need a website or a blog (which can be created for free here) where you post new articles frequently.
Here are the starters:
1.Build traffic to your website:This is the 1st and most important step.If you are successful in building strong traffic, you deserve to earn a lot( and surely you will).
The traffic can not be built up within a day but it's a long term process.If you have fresh and demanding content, search engines will love your site.Page ranks in search engines matter a lot in terms of traffic you get through them.
If you think that the topic of your website is not very different than other relevant websites, you can choose the other options like social networking websites, emails, forums/groups related to your topic.Social networking sites have really helped many websites to build good traffic.

2.Proper choice of Affiliate program:Now a days,because there are many choices available to choose an affiliate program from, it confuses the newbies (it is a nice confusion to get).
Here are some best performing programs as per the traffic you get:
A.Strong traffic:

Tribal Fusion
B.Moderate traffic:
Adsense,Bidvertiser(read more..),
Adbrite( read more..)
C.Low traffic:
Widgetbucks(read more..),
Matched.co.uk(read more..)

(Some programs like Adsense, Widgetbucks work good for all websites)

Once you are done with the two steps mentioned above (1st one takes time), believe me or not, you can even earn more than what you earn through your 9 to 5 work.
