Definitely start a twitter account, facebook, myspace, linked in and any other social media account with your domain name and create some content there. That should push it down some.
Probably the worst ones we've gotten were from mis-informed customers. One the customer called to cancel their order the day after it had shipped... he wrote a terrible review making claim that we refused to cancel... well duh... it had shipped.
Another one we contacted the customer to inform them of a backorder and told them if they wanted to cancel to contact us... we never heard anything and a couple of weeks later their item shipped. Their review claimed we never shipped their item.
Unfortunately both are on Google seller reviews and there is nothing we can do about it. We've contacted the customers numerous times with no response.
