Google has created a new tag to reduce the impact of comment spam. Comment spam is an effect particular to blogs, and other public areas that invite comments, and the subsequent abuse of this facility by site owners trying to get inbound links without merit from influential sites. The new tag allows site managers to identify links as being contributed without editorial contol and hence are potentially suspect. When Google finds this new tag (‘rel’), that has the attribute “nofollow”, it will discount any potential credit the link would otherwise provide.

Interestingly, Wikipedia has implemented this tag already, which is visible in the source code of any external links. This won’t affect the link from here to the Google Consultant entry, but it will have a bearing on any external links provided on that and any other page.
