There are two major types of business models that entrepreneurs use to make money blogging. The first  and most common way to turn a blog into a profit  making machine is to sell advertising to different  companies and brands who want to reach that blog's  readers. The second kind of money making blog is one  that helps a single brand improve its image by creating  positive associations between the blog and the product  in the mind of consumers. Both kinds of blogs can  make a lot of money, especially if the creator has a keen  mind for marketing.  

If you are blogging with the goal of selling advertising,  there are two basic ways that you can go about  recruiting sponsors who want to put ads on your site;  you can let someone else do all of the legwork, or you  can do the work yourself and keep all of the revenue.  Within the first group, many people make money  blogging by selling space through Google's AdSense  program. The advantages of this program are numerous,  as it requires very little effort on the part of the blogger  or webmaster to begin raking in profits. However, most  people discover that they make less money through this  method than they had hoped that their blog would earn.

Selling advertising directly to companies who want to  put banner ads or sponsored links on your blog can take  quite a bit of time, but it is often fairly lucrative. If you  have a lot of contacts in industries that are related to the  topic of your blog, you may want to try to go this route.  People who have a strong background in sales and are  experienced at pitching proposals can make quite a bit  of money by renting blog space to interested companies.  The most serious problem with this model is that you  often have to build quite a sizable readership before you  can attract advertisers, which can mean that you have to  do several months of work before you start to make  money blogging.

As blogging becomes a more and more lucrative  business, a lot of established companies are considering  how they can get into the action. One way that  companies are capitalizing on the blog movement is by  having blogs that provide a kind of friendly face for  their corporation. Often, a company will employ an  established blogger to create a weblog designed  specifically to appeal to that company's customers and  to create positive associations with the brand in  consumers' minds. More than one writer who never  even dreamed that he or she could make money  blogging has been approached by a company and  offered quite a pretty penny for this kind of gig.
