If I have a CMS that creates Event listings each with their own page. The permalilnks with the date: eg: /events/2011/03/09/karaoke It is nice to have seperate pages for each event because they can be shared individually. I'm worried however, that since we will have (Karaoke for example) listed every week, that we will be penalized for duplicate content. In a full year we'd have about 50 listings for Karaoke. Sometimes the Karaoke event will have different information, but for the most part not much changes from week to week for this particular event. The meta will show the date at least, but will we be effected because the content will be mostly the same each time?
