Using ad networks like adsense doesn’t prevent you from targeting advertisers directly. In fact, that’s how I started; I searched the net for potential advertisers who advertised products relevant to my content and offered them yearly packages. If you choose this option, bear in mind that you’ll need to provide traffic reports and other site statistics.
If retirement is a goal of yours (and who doesn’t want to retire someday?!?), it’s important to learn how to start investing. In fact, funding your retirement accounts should be at the top of your list. While these accounts won’t help your immediate situation, by stashing cash now, the residual income they create should help propel you through your golden years.
If you have specialized knowledge in a certain topic, you can put together an online course to teach others. For example, if you have experience in real estate investing, you can create an online course “Real Estate Investing 101”. The benefit of an online course is that once you create the course material, you can sell it to as many people as you want.
