rel="nofollow"

Robert Sayre: I noticed that the links his comment form have an interesting rel attribute.

Implemented.  Prediction: that wouldn't solve the problem.


I don't get it. They're trying to game search engines, and once search engines are unexploitable via this route, it's game over. It is after all a small pool of weblogging tools that generates the blogosphere link-torrent; I'd wager all of the tool authors are extremely clued in.

/guess I'm still confused..

I'm quite interested to see that the rel attribute is slowly gaining attention. Atom uses it extensively for its link elements, and Technorati have been using it for some of their HTML-based specifications, notably XOXO, XFN and now Technorati tags. Eventually the RSS community seemed to have cottoned on to this relatively unknown attribute.

It would be very interesting to see if there isn't a common thread of rel usage. I guess XFN may have preceeded Atom in rel usage. Atom's when I first became aware of it used in anger.

Sam,
Given that your site has permalinks that still display the comments such as [link] I'm not sure how you can actually implement this since robots can follow permalinks from other sites. Or is there also a way to put 'nofollow' in a span or div to designate a block of HTML which should be ignored?

Dare, the rel="nofollow" appears in each link element within the comments themselves.  View source for this page for example, and look at the source for the link in your own comment.

Does nofollow Have a Chance of Reducing Comment Spam?

Comment spam is one of the primary reasons that I don't have comments

this may happen eventually too). Google's nofollow

I've noticed that the [more] link you provide for trackbacks does not have a no-follow attribute.  Is this intentional or an oversight?  Trackback spam will only get more common over time.  Or does this indicate you've confirmed a link to your site exists on the linked page?

Posted by Jason Clark at

Jason, I plan to continue to fine tune this.  In fact, I just made a change to not insert rel="nofollow" on comments left by people who have commented in the last 90 days (which you have not) but have visited a web page within the past 7 days (excluding today) (which you have).  So this comment (and any you author in the next 90 days) should not be penalized due to the actions of a few spammers.

As to trackbacks... at the moment, it isn't a major problem, but I am monitoring this.  Yes, it was an intentional decision (the code is online here).

I am not shooting for perfection (which is unattainable), but to do something that is mostly right without requiring any explicit registration or administration.

OK, that change was incomplete.  Trying again.

Why no-nofollow

In a prior post someone commented: Wow - I hadn’t heard of the nonofollow movement. It seems to be predominantly peopled by SEO monkeys. Why are you joining up?

Excerpt from randomthoughts at

In my opinion, nofollow is not the right way to limit comment spam. A simple use of captchas is a good enough deterrent.. while it may inconvenience genuine people, but there’s a fair price to pay. Also, it could be programmatically arranged that people on your blogroll would be able to comment without the need for validating captcha text…. :)

Posted by saurab at

In my experience Nofollow links haven’t in any way prevented comment spam. I think if you really want to stop it you have to resort to other methods such as comment moderation or CAPTCHAS, at least then you aren’t punnishing your regular commenters...
