I have been reported for duplicated title with my Wordpress blogs. All duplicated title come with a page format + ?alexa_ho_am Ex. Each page has bene reported for duplicated under this format. http://www.domain.com/page/66?alexa_ho_am http://www.domain.com/page/66 I have already searched and found all Wordpress blogs come with a same format. I do not understand since the Blog has been like this from the beginning but this type of duplicated just reported a few days ago. I am deciding to do 301 redirect all page attached with "?alexa_ho_am" to a non "?alexa_ho_am" version to prevent duplicated issues. However, since all Blogs has this one attached so I am not sure if it would pose negative effects toward my blog or not.
