In light of Google's changes, it's more important now than it ever has been before to avoid any Black Hat or other dubious techniques such as those employed by DecorMyEyes. Google's got an especially sharp eye focused on this area now, and you don't want to be penalized or even get kicked out of the index altogether for attempting some of these ill-advised tricks.
Pay Close Attention to Reviews
If I'm correct and Google is actively incorporating customer reviews into its newly tweaked ranking algorithm, you're going to want to pay more attention to these than you may have in the past. Take a proactive approach and keep careful tabs on both positive and negative reviews from around the Web so that you can learn from them and address them quickly and appropriately.
Focus on Customer Service
This may seem like a no-brainer, but if you treat customers fairly and well--meeting or surpassing their expectations almost every time--you'll have fewer negative reviews to worry about.
This is particularly critical when customers are dissatisfied. Research has shown, in fact, that a customer whose dissatisfaction is resolved quickly and completely ends up being more loyal than one who never experienced that dissatisfaction in the first place.
There's a very good lesson in that. Do good, as the old saying goes, and good will come to you.
