Blogging can be serious work, and with your easy-to-use Tumblr blog, you might be posting more than ever. You may be writing about your beautiful vacation, sharing the newest wallpaper you designed in Photoshop, or explaining how to get your dog to quit barking at frogs.
Either way, your blog takes real time, and it might be nice to make a little money from it. Google AdSense has enabled bloggers around the world to get ad revenue from their content. The Tumblr Terms of Service require that your blog be used primarily for blogging, but they do allow you to use AdSense or other ad systems as long as that’s not the primary focus of your site. It’s fairly easy, so let’s see how to add it to your blog, no matter what theme you’re using.
