Welcome to WebmasterWorld Guest from 18.104.22.168
I often get questions from whitehat sites who are worried that they might receive duplicate content penalties because they have the same article in different formats ( e.g. a paginated version and a printer-ready version). While itís helpful to try to pick one of those articles and exclude the other version from indexing, typically a whitehat site doesnít neet to worry about 1-3 versions of an article on their own site.
however, you split the page rank that could be consolidated to one page because some links point to one version, while other links point to the other version.
i am working with enterprise sites that have thousands of duplicated articles. how much of a priority is it to handle this? will going for page rank consolidation through 301s or canonical tags provide a significant lift?
