Many of the people who write blogs today simply want to share their opinion on something. But then there are the business-minded folks, who have found a way to use blogs, or Web logs, to bring in a little extra cash too.
     You can start a blog and monetize it to earn money online. There are hundreds of blogs online which are making a fortune with this way - in fact this is the second most popular choice of persons who are interested or have already started to make money online. You can start a blog for free at Blogger, Wordpress, Typepad, MovableType etc but Blogger is the best choice. You can also start self hosted blog if you have money.
     If you're interested in taking it further — blogging for bucks, if you will — here are few strategies that could turn your blog into a moneymaker.
      1. Sell advertising. This is likely the most common means of leveraging a blog to generate income.  
2. Help sell others' products. Here is another click-through opportunity. Affiliate programs enable your blog to serve as a conduit between readers and online sites offering various goods and services.
3. Market your services in your blog. Many people associate blogs exclusively with a cyberspace-based soapbox — a place to shout your opinions and little more than that. Granted, blogs are an ideal venue to share your thoughts with others, but don't overlook their capacity to generate new business as well.
4. Use a blog to deepen your existing customer relations . Nor does any marketing material inserted in blog content have to be limited to bringing in completely new business. By using a blog to regularly communicate with existing clients as well as other readers, you can take advantage of the opportunity to fully inform them about everything your business does. That may expand your readers' understanding of the full scope of your products or services.
