Dun and Bradstreet. It's a name that has been synonymous with credibility for two centuries. Now, a separate organization licensed to use their name is under fire for allegedly acquiring inbound links and their SEO agency has been completely banned in Google.
Dun & Bradstreet Credibility Corp had links purchased for them by iAcquire. They were reported two days ago and Google deindexed the search company behind it. We will see what sort of penalty is imposed on D&B.
The automotive industry is one that is relatively-free of companies that use such techniques, but this should act as a reminder that trying to do things the wrong way can lead to disaster. Google's Penguin Update is a good thing for legitimate SEO firms. It makes quality out-perform quantity and highlights that manual, appropriate content marketing trumps spammy link-building any day.
