I looked all over the web, but I could not find an answer to this. We all know that Google treats different capitalization of Urls as potentially duplicate content. My question is, what about querystring parameters? For example, will Google treat this as duplicate content? http://www.example.com/forum?thread=first and http://www.example.com/forum?Thread=first Here, the url has the same capitalization. However, the querystring parameter Thread and thread have different capitalization for the letter T. How does Google treat querystring parameter capitalization? Does it ignore querystring parameter capitalization or will different querystring parameter capitalization lead to duplicate content penalties from Google?
Google and querystring parameter capitalization?
google;query string;url parameters
