I started my blog about programming yesterday and in order to promote and increase traffic I submitted my rss to Codeproject which pulls my posts and publishes them at Codeproject.

While it increases the number of people reading my posts (but they are reading it at codeproject) I am worried that Google will penalize my site for duplicate content (Especially considering that Codeproject has much more reputation compared to my new website). The post at Codeproject has a link back to my blog post but it does not have "rel=canonical".

So my question which one is better: a link from a high reputation website and some traffic or should I remove it from codeproject so that my blog is not penalized? What if codeproject adds "rel=canonical" to the link?

About a year ago Google tackled this problem by creating Source Attribution meta tags:

  • syndication-source: this meta tag is used to point to the long-lived (bookmarkable) URL of the original article. This should be used on all pages that republish the syndicated content, but it can also be used on the original page to point to itself as the syndication source.
  • original-source: this meta tag is used to point to the article that first broke a story. It should be used on an article where you're referencing facts/info from another source that first broke the story and want to give credit. Or it could be used in an article to point to itself to indicate that the article consists entirely of original reporting.

According to Google, only one of these tags should be used, though IMO there are certainly legitimate cases for using both, since an article comprised of original reporting could also be a syndicated article. But Google will apparently only choose one to use if both are present.

Also, Google claims that the original-source tag will not currently affect ranking at all, as it's more of an experimental tool for detecting originality amongst news and journalism. However, this could change once sufficient data has been collected.

I don't frequent Codeproject, but if they're not using the syndication-source meta tag on the full-version of the republished article, then I think Codeproject users need to start applying pressure on the publisher to start doing so and give credit where it's due.

  • I had a look at the source code and there is nothing similar to the tags you mentioned. Is it enough if Codepoject adds syndication-source tag or is rel='canonical' also required?

  • @Giorgi: Technically, they're for completely different purposes; in this case canonical isn't required, as it's legitimately syndicated content rather than a duplicate. Remember, canonical is designed to be used where a 301 redirect can't be used. And Codeproject certainly wouldn't want to 301 redirect their page to your original; nor would they want their page to be deindexed. The syndication-source tag lets them give you proper attribution without their republished version being eliminated from search results. Commented Dec 22, 2011 at 2:54

    The article you linked to is about the (related) Standout meta tag. When do you use that vs. the original-source tag? Commented Aug 26, 2015 at 22:51
  • OK, I see that original-source is for reprinting an article with small (or no) changes (i.e., reprinting or syndication). Standout is for referencing another source that first broke a story. Commented Aug 27, 2015 at 0:42

    Syndication-Source has been deprecated. : productforums.google.com/forum/#!topic/news/Bj2lzoy45Rw I would have reported that earlier but I could not find a canonical source ;-) Commented Aug 27, 2015 at 19:54
