Hm.. I don't believe that is something you can change. Do you have a direct link to the blog page? When I look at your live site I don't see any links that would show up this way, but I could be wrong about how it's displayed in stats. It seems to me that if I'm on a blog post and click a link to a new post it would show up like "iot-knowlegde-center/blockchain-can-revolutionize-pharmaceutical-supply-chain" as the referring page. Maybe @Adam has a thought on this?
