As you many of you already know,since google panda update google is now very sensitive regarding duplicate content which making it problem if you are blogger since blog script automatically have many duplicates.For example first we have pages,starting from 1 to last number.So we have same content which is on page one also which is homepage and when we click on post.So basically that is 100% duplicate content unless post have comments which make it a little less duplicate but still it is duplicated.Duplication goes even further if you use categories and mark some posts with multiple categories.So is it possible to fully eliminate any duplication on blog script for example like wordpress?Any plugin which would help with that?I know that could be done by automated 301 redirect or canonical tag but it is still question how to resolve what is showed on home page and rest of pages.Perhaps eliminate pages and use categories for navigation,and on homepage use totally original content or just links with short but different description to blog posts ?
You can use noindex meta tags on pages that have duplicate content as you don't want google to index those.
