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.
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.
Hi Sam! I love your site. We should definitely connect. I’m a school counselor and recently launched a site for parents to address pertinent teen topics. Like you, I struggle with the ultimate service I’d eventually offer on my site, but Ramsay’s idea is a great start. He’s absolutely right that people are looking for fresh content for their sites! Best of luck to you and I hope we can collaborate.
