Do you ping your own blog?
If yes, then do stop it. I have seen many bloggers, even some professionals, pinging their own blog. Some think that in this way, they do get a linkback to their posts. The link to your post might appear in your related or recent posts. Or, you can deliberately too induce a link in your post. But, this-way linking in your comments section should be avoided.
Moreover, self-pinging is not good as part of SEO. So why not avoid it. In wordpress blog, you can stop self pinging your own blog easily with the help of a plugin called ‘No Self Ping’.
