Duplicate content and rel canonicals?
-
Hi. I have a question relating to 2 sites that I manage with regards to duplicate content. These are 2 separate companies but the content is off a data base from the one(in other words the same). In terms of the rel canonical, how would we do this so that google does not penalise either site but can also have the content to crawl for both or is this just a dream?

Hi,
I have to agree with Devanur-Rafi. If both of the sites are serving the exact content, although Google have the power to do whatever they want, they'll most likely take the rel=canonical into consideration and display the page the tag is pointing to over the second site.
So, yes it is a dream to display both site with the same content in the search result and by using the canonical tag, Google won't penalize both sites and display the preferred site.
That's my 2 cents.
Thank you!

Hi William, thanks for sharing your experience here. My experience has been totally different from that of your's.
Here is what Dr.Pete has to say..

2) Can I Use Rel=Canonical Cross-domain?
Yes – in late 2009, Google announced support for cross-domain use of rel=canonical. This is typically for syndicated content, when you’re concerned about duplication and only want one version of the content to be eligible for ranking.
(3) Should I Use Rel=Canonical Cross-Domain?
That’s a tougher question. First off, Google may choose to ignore cross-domain use of rel=canonical if the pages seem too different or it appears manipulative. The ideal use of cross-domain rel=canonical would be a situation where multiple sites owned by the same entity share content, and that content is useful to the users of each individual site. In that case, you probably wouldn’t want to use 301-redirects (it could confuse users and harm the individual brands), but you may want to avoid duplicate content issues and control which property Google displays in search results. I would not typically use rel=canonical cross-domain just to consolidate PageRank.
Best regards,

Its true they are a strong hint but when the domains are not the same, the canonical tag will not work as well as you would think.
I've attempted this personally and it didn't work that well.

Except for very exceptional cases, Google considers and respects the rel=canonical implementation and its a strong hint for them.

The canonical tags as mentioned by Kingof5 is directional. Google can still do whatever it wants.
Preferably you should canonical the duplicate pages to the original but that may cause one to not be indexed. That still may help as the authority from the other site will be forwarded (theoretically) to your canonical page.
But yes, it is a dream.

There are no absolutes with canonicals. Google treats them as suggestions, not rules.

Hi, with rel=canonical in place, there is no way that both the pages from the two sites appearing and ranking in the search results. Only the canonical or the preferred page will be indexed and can rank in Google.
You should be thinking along the lines to make the content on both the sites unique. Though these two sites operate and target the same niche, you can definitely make the content unique from each other.
Best regards,
Devanur Rafi

Duplicate content or Duplicate page issue?
Hey Moz Community! I have a strange case in front of me. I have published a press release on my client's website and it ranked right away in Google. A week after the page completely dropped and it completely disappeared. The page is being indexed in Google, but when I search "title of the PR", the only results I get for that search query are the media and news outlets that have reported the news. No presence of my client's page. I also have to mention that I found two URLs of the same page: one with lower case letters and one with capital letters. Is this a duplicate page or a duplicate content issue coming from the news websites? How can I solve it? Thanks!

Duplicate Content - Mobile Site
We think that a mobile version of our site is causing a duplicate content issue; what's the best way to stop the mobile version being indexed. Basically the site forwards mobile users to "/mobile" which is just a mobile optimised version of the original site. Is it best to block the /mobile folder from being crawled?

Canonical tag in preferred and duplicate page
Hi, I have a super spiffy (not) CMS that tends to create some pages at the root level of the site (not where I want it) i.e. www.site.com/page.htm as well as the desired location i.e. www.site.com/category/keyword/page.htm . Now obviously a canonical tag inserted into the URL at the undesired location would be the best option, however the source code is exactly the same for both pages (can’t change this) i.e. if I put the canonical tag that reads www.site.com/category/keyword/page.htm"/> it will appear in the head section of both pages, the desired URL and the non desired URL. Will a canonical tag inserted into the head section of a the preferred URL directing the search engine spiders pretty much to itself cause more grieft than the solution it offers re duplicate content ?

CGI Parameters: should we worry about duplicate content?
Hi, My question is directed to CGI Parameters. I was able to dig up a bit of content on this but I want to make sure I understand the concept of CGI parameters and how they can affect indexing pages. Here are two pages: No CGI parameter appended to end of the URL: http://www.nytimes.com/2011/04/13/world/asia/13japan.html CGI parameter appended to the end of the URL: http://www.nytimes.com/2011/04/13/world/asia/13japan.html?pagewanted=2&ref=homepage&src=mv Questions: Can we safely say that CGI parameters = URL parameters that append to the end of a URL? Or are they different? And given that you have rel canonical implemented correctly on your pages, search engines will move ahead and index only the URL that is specified in that tag? Thanks in advance for giving your insights. Look forward to your response. Best regards, Jackson

Is this considered as duplicate content?
One of my clients has a template page they have used repeatedly each time they have a new news item. The template includes a two-paragraph customer quote/testimonial for the company. So, they now have 100+ pages with the same customer quote. The rest of the page content / body copy is unique. Is there any likelihood of this being considered duplicate content?
