People blog mainly for two reasons.

Some bloggers blog just for fun, meaning they don’t have any intention of making money with their blog.  They merely want to share their views and thoughts with other people online.

On the other hand, many bloggers blog to make money online.

There’s a few ways to make money with your blog.  By the way, if you don’t know what a blog is, it is a website that contains a continual amount of posts that a marketer makes – about whatever they’re wanting to talk about at the time. The blogger controls what gets posted and controls what people can comment on.  The posts can contain information on their niche, product reviews, rants about any topic they wish,  recommendations, etc… basically anything they want to talk about, can be on their blog. If you post valuable information often, you can end up with alot of visitors that come to read your blog – which means money for you.  How you ask?  Well when you get visitors you can have Google Ad Sense ads on your blog which earn you money when visitors click on the ads.  These ads display to your visitors offers related to what is being talked about on your blogs. You can also make money by placing ads to other people’s products on your blog, this is called being an “affiliate” for them. If your visitors click on those banners or text ads and make a purchase you get paid for referring them.  Another way to make money with your blog is to sell ad space on your blog for a monthly fee. If you get a substantial amount of visitors to your blog every month and can prove it, you can easily rent this ad space out to other marketers who want to tap into your blogs visitors. And of course, if you have your own products, that is the 1st thing you should promote on your blogs! You can make a great income with your blog by promoting affilate products, placing Ad Sense, or promoting your own products and services.

The key is to get started building your blog.

One example of affiliate marketing is Megamarketingtools, where you get paid every time somebody you refer chooses to buy the service and start building their own personal blog.
