Welcome to the Q&A Forum

After comparing your links, I see that there are a few parameters that your ticketing platform added to the end of the URLs, like ReturnURL and CntPageID. You can go into your Google and Bing Webmaster Tools, and Yahoo Site Explorer as well, and tell these search engines to ignore those parameters on all URLs of your site. I'd also recommend canonical URLs if you have the option in your ticketing system. Now I'm not sure whether or not those parameter handling settings will be sent to SEOmoz when linking to Google WMT. Anybody?
