I have a website which has events. Events have description, dates and locations. Single event may be held in multiple locations on different dates, but the description is still the same.How can I prevent duplicate content on such events or this case is OK for search engine optimization?
Duplicate content in event profile pages
google search;duplicate content
According to your current setup:You have dedicated page for every event with the details of that event.Every event may have multiple locations / dates and for those locations / dates you have event listing pages.The listing pages for locations / dates contain short description of the original events. Other than that they don't provide any additional unique information.For this sort of structure, abide by the following two rules for better Search Engine Optimization (SEO):Make sure each dedicated event page have rel=canonical properly set to it's own URL. You'll find details on canonical here.Since your event listing pages for locations & dates do not contain any additional unique information, there is no reason to index them for search engines. You may use noindex meta tag to prevent Search Engines from indexing them for search results. Search Engines will still find your events, but they'll simply show the dedicated event pages in the Search Result.You'll find more information on noindex here and here.This way Search Engines will index all your unique event information without any duplicates.
