We maintain a blog using WordPress. Posts from our blog are regularly bookmarked/shared on several bookmarking and sharing sites. On relevant search results page, bookmarking sites rank higher than our site which has the original content.
E.g. the keywords "comment creer trafic" on google.fr rank Youvox.fr higher than our site (thepalermoproject.fr)
Is there any way to ensure that our site ranks higher in such cases?
