I just read a blog post on QuickSprout. Neil says that if you syndicate your article from your own site or post snippets to other sites, your site will be hit by duplicate content penalty. His observation is based on his own site - QuickSprout. Though his data supports his claim, yet I'm not convinced that it is 100% valid based on a single isolated observation. Code: http://www.quicksprout.com/2014/11/03/should-you-repost-your-blog-content-on-other-websites/ His article was syndicated to high authority sites eg. Entrepreneur.com. I thought that is great as Entrepreneur.com has high traffic, funneling traffic to his site. But he only showed decline in traffic from Google. He didn't mention referral traffic from Entrepreneur.com. If I remember correctly, duplicate content penalty only happens on your own site. Adam, a member of this forum conducted a test on a single syndication using Web 2.0 and his client's site was not penalized. In fact, the result was impressive even after Penguin 3.0. Again, it is only one site tested. What do you guys think about it?
