I have a situation that I do not fully understand, related to syndicated content. My site - where the original version of my articles is being published, is being seen by Google not as the original/canonical version. Instead, the site that is syndicating the content is seen as the original version.
This doesn't look to be a simple case of both versions are valid, but the syndicated site is just better promoted, but that it's actually the original version, for several articles.
For example:
The syndicated version is on 3rd place, my own content doesn't appear in the first 100 results.
The website that syndicates my content does have a link back to my article; it also has the date on the article page, but it looks like this is the updated date, not the published date:
<span class="date updated">May 7th, 2013</span>
On my website, the date looks like this:
<abbr title="2013-05-01T16:13:14+0000" class="date time published">May 1, 2013</abbr>
Should the syndicating site also use proper timestamps and a publish date? Can this be the reason Google picks it up as the original version? Also, is there any way to fix this problem?
