I wasnt able to find any good answers on this.  I have two separate ecommerce websites, one with a top level blog.  (www.xyz.com/blog) and different website with a subdomain blog (blog.xyz.com)***note on the subdomain blog, although it links to our website.  You cannot directly shop from it.  Until i can make some sort of scraper, its what I have to work with. For quite some time now I have been copying the blog posts and re-creating them on facebook as a Note.  Using the same anchor text/links on facebook as my blog post. Part of the issue is that I want the facebook pages to have some content and not just links.  Both get 2-3 updates per week, 1 of those being a blog re-post. Does anyone know if google or bing considers this duplicate content?  Should I simply link directly to the blog everytime, as a best practice? Any insight on this would be great.  Thanks!
