I’m a bit confused…are you talking about using WordPress.com or WordPress.org when setting a blog? I heard not to use WordPress.com for a blog even though its free because the blog isn’t really “yours” and they can do what they want with it. Can you clarify the difference between the .com and .org and which one should be used in setting up a website and blog?
Perhaps the most popular network for placing these types of ads is Google AdSense. With this program, you do not need to be in direct contact with advertisers; you simply place the banner on your site, Google chooses ads relevant to your content, and your viewers click on the ads. There are countless similar programs available if you find that AdSense doesn’t work for you, such as Chitika, Infolinks, and Media.net.
