I already had someone steal our site and now Google is black listing us. I don’t get it….somehow they got the content crawled first and then BOOM! Oh well, making more content! Thanks for the tips!

I did some testing recently: If you investigate a search for a keyword that is so common that nobody would even think of optimizing a website for it, like maybe “com”, it will dig up preferably websites from the .com TLD which is quite natural, and I found it amazing that large sites with a lot of content and/or change frequency (of the website in total, not necessary of a single document) seem to be preferred. So this would confirm your conclusion that smaller sites are disadvantaged.

@Introspective: yes, in fact if you are publishing your own content on your own site AND the article directories you’re running the risk of doing more harm than good to your site

@frank carr: I agree that google sometimes lists a fraction of the duplicated pages in the unfiltered results. it’S not a myth, but Google tries to present a small selection of DUPE content… however from my observations I see that typically a 10th of the dupe content pages are shown – at max – … so if you see 100 results for a dupe song lyrics you can be SURE that there are 1000 pages carrying that song lyrics that are filtered (and a part of that shown in the unfiltered results)

I used to publish my articles, but now I wander should I stop doing this, because the risk of duplicate content penalty. Should I stop publishing my articles on article directories?

I’m with Gero on this one, I’ve seen this dozens of times. Google is associating some of the pages with one domain and the rest of the pages with the other domain. This is pretty common when a website is mirrored on two domains. Just look at the cache of the homepage. http://74.125.47.132/search?sourceid=navclient-ff&ie=UTF-8&q=cache%3Ahttp%3A%2F%2Fwww.toronto.edu%2F

The homepage cache is associated with the utoronto.ca domain. You wont find the homepage cached on the other domain. (check for yourself). If you want to investigate dup content, the first place to look is Google’s index and see which pages are getting cached.

Wow, what a great analysis! Thanks for this really fine piece of information about trusted sites ranking with dupe content. Also thanks for doing so much for the community by sharing all this on your site for free Chris.

Best from Hannover,

I have found quite by accident exactly the same results as you found. Last year I was testing a CMS we built to manage a bunch of sites. I simply copied and pasted an article about the property market in Paris that had just been published by a major news outlet into the “new post” form for an old, trusted site I owned. I published the exact copy and within 20 minutes it was indexed and was beating the major news outlet in Google SERPs!

For most of the duplicate contents the domains are only indexed and ranked with only one version, e.g. http://www.utoronto.ca/tsq/ vs. http://www.toronto.edu/tsq/, http://www.utoronto.ca/ceres/ vs. http://www.toronto.edu/ceres/ – one version has got good pagerank and the other version has got “bad rank”… the site-request for both sites is also completely different…

I’ve seen a lot of Domains with identical contents and own backlinks, where google indexed some documents with one domain and some with the other and some for both.
In Your example both domains are both strong enough to keep some of their sites in the index and rank them.

i still believe there is no thing such a DC-Penalty but a DC-Filter that kills the dupes. the problem is, that you share domain & linkpop for both domains and lose the incoming links for the dropped dupes. therefor a 301 would be a good idea.
