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..
Taken from: http://moz.com/blog/rel-confused-answers-to-your-rel-canonical-questions
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

Does duplicate content not concern Rand?
Hello all, I'm a new SEOer and I'm currently trying to navigate the layman's minefield that is trying to understand duplicate content issues in as best I can. I'm working on a website at the moment where there's a duplicate content issue with blog archives/categories/tags etc. I was planning to beat this by implementing a noindex meta tag on those pages where there are duplicate content issues. Before I go ahead with this I thought: "Hey, these Moz guys seem to know what they're doing! What would Rand do?" Blogs on the website in question appear in full and in date order relating to the tag/category/what-have-you creating the duplicate content problem. Much like Rand's blog here at Moz - I thought I'd have a look at the source code to see how it was dealt with. My amateur eyes could find nothing to help answer this question: E.g. Both the following URLs appear in SERPs (using site:moz,com and very targeted keywords, but they're there): https://mza.seotoolninja.com/rand/does-making-a-website-mobile-friendly-have-a-universally-positive-impact-on-mobile-traffic/ https://mza.seotoolninja.com/rand/category/moz/ Both pages have a rel="canonical" pointing to themselves. I can understand why he wouldn't be fussed about the category not ranking, but the blog? Is this not having a negative effect? I'm just a little confused as there are so many conflicting "best practice" tips out there - and now after digging around in the source code on Rand's blog I'm more confused than ever! Any help much appreciated, Thanks

Handling of Duplicate Content
I just recently signed and joined the moz.com system. During the initial report for our web site it shows we have lots of duplicate content. The web site is real estate based and we are loading IDX listings from other brokerages into our site. If though these listings look alike, they are not. Each has their own photos, description and addresses. So why are they appear as duplicates – I would assume that they are all too closely related. Lots for Sale primarily – and it looks like lazy agents have 4 or 5 lots and input the description the same. Unfortunately for us, part of the IDX agreement is that you cannot pick and choose which listings to load and you cannot change the content. You are either all in or you cannot use the system. How should one manage duplicate content like this? Or should we ignore it? Out of 1500+ listings on our web site it shows 40 of them are duplicates.

Duplicate Content within Site
I'm very new here... been reading a lot about Panda and duplicate content. I have a main website and a mobile site (same domain - m.domain.com). I've copied the same text over to those other web pages. Is that okay? Or is that considered duplicate content?

Content Duplication and Canonical Tag settings
Hi all, I have a question regarding content duplication.My site has posted one fresh content in the article section and set canonical in the same page for avoiding content duplication._But another webmaster has taken my post and posted the same in his site with canonical as his site url. They have not given to original source as well._May I know how Google will consider these two pages. Which site will be affected with content duplication by Google and how can I solve this issue?If two sites put canonical tags in there own pages for the same content how the search engine will find the original site which posted fresh content. How can we avoid content duplication in this case?

Duplicate Content Errror
I am getting a duplicate content error for urls for the "tags" or categories pages for my blog. These are some the URLs that SEOmoz is saying are errors, or duplicate pages. http://sacmarketingagency.com/blog/?Tag=Facebook http://sacmarketingagency.com/blog/?Tag=content+marketing http://sacmarketingagency.com/blog/?Tag=inbound+marketing As you can see, they are just the pages that are aggregating certain blog post based on how we tagged them with the appropriate category. Is this really a problem for our SEO, if so any suggestions on how to fix this?
