Linking back is always good, however WordPress displays these links using the “nofollow” attribute. So is it good to allow a nofollow linkback to your own website? Considering Google’s new policy changes with regards to nofollow links, and how you might eventually lose ranking over it, adding an additional linkback to your own blog with a nofollow link definitely does not gauge well.
On my tech blog I use a plugin called No Self Pings, which in turn does not send pings to my own blog whenever I link internally. Of course many might think that doing away with this functionality might gain lesser conversions. However, you can always try out a related posts plugin, which in turn adds posts that are related to the current one. You will find several of them in this search for “related posts”.
You might also want to read a post from Matt Cutts, the head of the Google Spam team to understand the changes to nofollow links, and why it would convert to lesser ranking for your blog.
Rest aside doing away with “nofollow” is not the solution. If you are against the use of nofollow in comments and pingback, you might want to read a earlier post of mine about dealing with spam.
What do you think? Should you ping your own blog and add “nofollow” links or should you use the plugin and get rid of it?
