If you have sitelinks for your listing (I've noticed they only tend to show up when searching for the company or brand name) make sure they are relevant and work properly. If they don't, login to Google Webmaster central (http://www.google.com/sitemaps) and exclude them. I've found several of my sites contain links within the sitelinks that are irrelevant or even broken pages. However, as I write this, I have yet to see the pages I requested be excluded actually removed, and I put in the request 24 hours ago.
