The no follow link tag has done a lot of good for the online world – most SEO spammers won’t bother posting irrelevant links to blogs or forum posts if they know they won’t get to publish a follow link. WordPress automatically assigns the no follow link attribute to all user-submitted links, and Wikipedia does the same for its reference section.
While blog comment spam still happens, no follow definitely dampened it.
As a webmaster, you might find yourself wondering when to use the no follow attribute and when to allow for do follow links. No follow links primarily belong in:
- Paid links (it wouldn’t be fair to buy link juice, now would it?)
- Anything involving what Google calls “untrusted content”
