In this economy, people are constantly searching for ways to 
supplement their regular income. This includes getting a second or even a
 third job to do just this. The internet is one such opportunity where 
one can earn a stable income, if you know how. There are certainly many 
ways to earn money online. One such way is through blogging.
Contrary
 to popular beliefs, having a blog can certainly earn you money online. 
This is can be done by having advertisements on your blog. This could be
 in the form of having text or even banner advertisements from Google 
appearing on your blog. This strategy is known as "Pay Per Click" or PPC
 in short. Google will share its revenue with you when someone clicks on
 the advertisement on your blog. If the topic of your blog is from a 
competitive niche, you could even earn $30 per click.
The other 
way to earn money on blog is to promote an affiliate campaign. Affiliate
 marketing is slightly from "Pay Per Click" in that it requires the 
person who clicks on the advertisement to buy a product. When this 
happens, you will be paid a commission or fee. Depending on the 
affiliate program you join, this commission could be a percentage of the
 price paid for the product.
If the product you are promoting has 
several "One Time Offer" (or commonly known OTO) after the initial 
purchase, this commission could certainly stake up.
There are many
 affiliate programs that you can join to make money from your blog. One 
such program is ClickBank. The products on ClickBank are normally 
information products such as eBooks, home study courses or even 
software.
The other interesting affiliate program that you can 
join is Amazon Associates. While many of us think that Amazon is all 
about books, we cannot be more wrong. We can certainly find lots of 
interesting products within Amazon. This includes clothes, home 
furnishing and others. You can even find spare part for cars being sold 
in Amazon.
In terms of rewards, ClickBank would pay as much as 75%
 of the purchase price as commission. Amazon Associates on the other 
hand, would pay from 4% upwards for your effort.
If your blog is 
an authority in this subject matter, you could even sell advertisement 
space. It is not uncommon for large corporates to pay as much as four 
thousand dollars per month as advertisement fees.
