The well covered issue of comment spam & nofollow

Lee Odden     Online Marketing

Google, Yahoo, MSN, several major blog software services are supporting the implementation of a nofollow link attribute in an effort to quell comment spam. Of course this relies on the owner of the blog or web site to actually implement the tag properly or at all, in order for it to be effective. As far as blogs go, I would expect the 80/20 rule probably applies in that the smaller percentage of blogs recieve the majority of traffic. Those bloggers are most likely to be very savvy to the comment spam issue because of their visibility and involvment. They’re most likely to start using such a tag. But it will take a long time without mass acceptance which appears to be happening.

    I don’t like comment spam but I don’t no if I support doing this because I don’t mind people that come to my blog to have a link. Share the wealth.

  2. It will depend if the blogging software services like blogger use the nofollow tag as a default. Perhaps they will offer it as a functional option in the comment preferences so you can enable/disable like other features.
