My Adsense ads are only earning for me on one of my articles (Echinoderms Facts). Do I need to manually place them on each article, or is something wrong? When I was sent the email saying that my account had been confirmed, it said that "ads would begin showing on" and then had a link to one of my Hubs. Then when I went to manage the earning, it said I had 27 page views. I was like "what? I have WAY more than 27 views". Then I realized that the article it had said has 27 views. In other words, none of my hubs are earning for me except one, and I want to know what's wrong and how to fix it.
