I write some unique article in my website or blog. And for the purpose of marketing it i share part of the content in some high PR social bookmarks and social medias on the same day or the day after. Will that make my content in my site duplicated? I ask this because when i search Google for that content those social shares comes in first few positions and my own site below that. If this really is a problem, how else can i do content marketing? Thanks i advance...
If Google caches and indexes your article before indexing the social bookmark links, then you are on the safe side. But, why do you post part of the content on PR sites? We generally prepare a keyword rich contextual snippet to post on bkmrking sites.
