Google have announced a new tag that should remove the motive for content spamming.
From now on, when Google MSN, and Yahoo! see the attribute (rel=”nofollow”) on hyperlinks, they will now no longer index any such links.
Be aware that there is a typo in the published code – I have commented on Keith’s site to make him aware of this but just in case you miss that, remove the space in the first line before the ?PHP if one exists – if there is no space there, Keith has probably fixed it.
This nofollow tag won’t be a quick solution to this problem, as it won’t be implemented in all blogs for quite some time, so the incentive to spam will still exist. Spammers are not going to go the trouble of trying to see which blogs have implemented this, so don’t expect a dramatic fall off in the amount of spam in the next couple of days or even weeks!
