I read a lot of posts by people who go around saying that Tier 1 links need unique content or they wont get indexed because of duplicate content penalties. This makes no sense because all over the web people steal or cite someone as a source of information all the time. I myself have tested this with my own website (guest blogged then syndicated article with attribution link) and within a couple of hours it was indexed. I encourage you guys to write one high quality article and then repost it to dozens of high quality web 2.0 sites. I bet they will get indexed better than the spun content. Think about it. Why would Google penalize your website if someone else took your content and posted it to their own site? If anything that shows your blog is popular enough to get its content stolen in the first place. Duplicate content applies to the same content on ONE website not across many. Of course, spamming one article thousands of times is not natural but I think with across 50-100 Web 2.0s is fine. Tl;dr: Duplicate content is same content across one site. Links will still get indexed since content syndication happens across the net all the time. Try stuff before drawing conclusions and believing people (even this post.) Make sure you credit yourself as the author, don't leave a footprint by syndicating only yourself across your web 2.0 sites. Don't be stupid and syndicate the same article, from the same author, linking to the same site, across the same 50-100 websites. Other comments/urls http://www.searchenginejournal.com/syndicated-content-duplicate-content/28833/ Repost.us offers FREE content for you to syndicate(advertiser actually want syndication for links). Search for a popular article and Google that snippet of text and see if there are more than 1 URL indexed. If duplicate content existed then why do press release sites get indexed when all they do is syndicate content?
