Hello - I'm contemplating buying a directory listing on the software promotion website http://www.capterra.com/ . It's a site that gets quite a bit of traffic for people searching for software products and  I was interested in promoting my software product there, but I don't want to ruin our very good standing with Google at this time if Google deems Capterra as selling paid links. I'm not interested in this for links but instead as a good source of referral traffic for my software site. If anyone has used Capterra or has advice on whether Capterra might injure my SERP rankings, I would appreciate it. Thanks, Jeff
