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.
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?
