Hi all, I got a question about pinging. How important is it that you do it? When you build a backlink, should you rightaway ping it? What happens if you ping a link that has been built some time ago, any chance of google penalties here. All the ping services i've seen seem to be for blogs. Can I / should I use them as well for links built on directories, social media, articles sites? Or just any link whatever? I've been using pingfarm. Is there something better? Or should I use more than one service? Sorry for the noobness of this post. Would be great if someone could make a sticky thread about pinging. Thanks!
