Be aware that many blog hosting services only allow their proprietary contextual ad service, and may shut down your blog if you use one not made by the host company. If you are hosting your own blog, you should research contextual ad services and choose one that shows appropriate ads. Some allow pornography or other ads that may not be suitable for your blog.
Just be aware that affiliate marketing with the wrong company can damage your brand. For instance, I started my blog w/ Blue Host because of Pat Flynn’s recommendation – which I am sure he was paid for. I am now on day 5 of my site, and e-mail being down, with NO estimate from Blue Host as to when it will be back up. As a consequence, I wouldn’t buy a thing he suggested or endorsed, because of my experience with someone he put his seal of approval on. Blue Host has a HORRIBLE reputation among the community, and I even wonder if anyone would “recommend” them unless they were being paid.
Within a month, I had On Moneymaking off the ground, and within two months, it was getting 2,000 visitors a day and Performancing nominated it for the best business/money blog of the year. A couple of months after that, Brian Clark asked me to become the Associate Editor of Copyblogger, and so I sold On Moneymaking for five figures and went to work at one of the most popular blogs at the world.
One attractive feature of promoting digital information products is that the commissions tend to be higher than that of physical products; ranging anywhere from 10% to 50% or even higher. As an example, if someone is selling a digital information product for $500 with a 50% commission - you can earn $250 per sale. This is much higher than commissions on physical products due to the high profit margins.
If you want to be famous or reach a wide audience, you will have to choose something slightly broader and work hard to make the best content for that topic. A subtopic relating to fitness, finance, or relationship advice is likely to reach the most people. Consider specific but broadly applicable topics such as managing money in college, or a marriage counseling blog.
WordPress also have a variety of plugins that make it easy to put social sharing buttons on your blog posts. Some people like to limit the number of plugins they use on their WordPress blog because it can slow the blog down and it can open your blog up to more attacks, butt a social sharing plugin is one that should have high priority if you do choose to use plugins.
Use a contextual ad service. Once your blog contains high quality content and has begun to attract an audience, you can make money using Google Adsense, WordAds, or any other contextual ad service. These automatically generate ads in the amount, size, and placement you specify, matching the ads chosen to the topics you write about. The more readers who click on the ads shown on your site, the more money the advertisers will pay you.
If you’re passionate about something, it will show in your content. Readers will be able to see your genuineness and will be attracted to that. This is probably the most important thing you will learn about blogging. You can try everything in the world and use every tool known to man to be successful, but if you’re not genuine, people will see right through it.
