" If you link to something with the intent that it should help your Google rankings " well, I won't copy the rest but if I google your topic, the answer is there in plain site.
However if folk post links, I say "don't fret about it." Worry about your own work.
Besides rankings are now so messed up by bots that I don't think they are worth much. I have this video available on that!
i have a tech blog in blogger and i applied the no follow tag automatically to all my blog external links. i don't know if there is anyway i can fix some links do follow on that same coding because some of my guest posters needs there links to be do follow.
would be looking forward to hear from you guys.
