"Wired has a series of How-To pages that run off of a Wiki-style system, allowing anyone to add or edit a page. And, unlike Wikipedia, they haven't included \"nofollow\" commands in their external links, meaning that any link placed in a page gets indexed as an incoming link for sites.\nThis may sound wonderful, but now that it has been figured out, it could turn these useful pages into a marketing spam haven for unscrupulous SEO marketers.\u00A0 Go into a how-to page, make a tiny edit, throw in a link.\u00A0 Create a whole new page about how to get dust off a screen, throw in a link to a site.\u00A0 The system could quickly get abused if Wired doesn't start adding the \"nofollow\" tag.\nWhen Search Engine Land found the problem, they created a test page to demonstrate the problem with the system not having safeguards on it, and they were quickly labeled as spammers for creating a spam page.\u00A0 There was also a note posted saying that it was not possible to use \"nofollow\" in a Wiki-based environment.\nSay what?\nWikipedia's use of \"nofollow\" raised quite a stir in SEO circles when it was first implemented, and it is still in use by them.\u00A0 The tag is a deterrent for people from abusing the system, and it could easily be added to Wired's system.\u00A0 Maybe they just don't know how?\n(via Search Engine Land)"^^<http://www.w3.org/2001/XMLSchema#string>
