I trashed 88 comments today, all from me.
Actually, what I did was disable the WordPress gizmo that sends a ping back to a previous post on the same site, mostly because I thought it looked like clutter, and self-important clutter at that. (I want pings and trackbacks from the rest of you, not from me.) This has bothered me for some time, and now apparently it bothers Google:
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.
Not that I’m especially concerned about my PageRank, which has been 5 for several years, except for about an hour and a half when it was 6. But I figure I have nothing to gain by appearing to game the system even if I’m not.
So I installed this plugin, which coincidentally is three years old today, so there shouldn’t be any more of that self-referential stuff in the comment listings. I do enough of that in the actual posts.
