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 question
Hey Mozzers! I received a duplicate content notice from my Cycle7 Communications campaign today. I understand the concept of duplicate content, but none of the suggested fixes quite seems to fit. I have four pages with HubSpot forms embedded in them. (Only two of these pages have showed up so far in my campaign.) Each page contains a title (Content Marketing Consultation, Copywriting Consultation, etc), plus an embedded HubSpot form. The forms are all outwardly identical, but I use a separate form for each service that I offer. I’m not sure how to respond to this crawl issue: Using a 301 redirect doesn’t seem right, because each page/form combo is independent and serves a separate purpose. Using a rel=canonical link doesn’t seem right for the same reason that a 301 redirect doesn’t seem right. Using the Google Search Console URL Parameters tool is clearly contraindicated by Google’s documentation (I don’t have enough pages on my site). Is a meta robots noindex the best way to deal with duplicate content in this case? Thanks in advance for your help. AK

Database driven content producing false duplicate content errors
How do I stop the Moz crawler from creating false duplicate content errors. I have yet to submit my website to google crawler because I am waiting to fix all my site optimization issues. Example: contactus.aspx?propid=200, contactus.aspx?propid=201.... these are the same pages but with some old url parameters stuck on them. How do I get Moz and Google not to consider these duplicates. I have looked at http://moz.com/learn/seo/duplicate-content with respect to Rel="canonical" and I think I am just confused. Nick

Categories and rel canonical
Hello everyone, I have a doubt in how to approach this problem. I have a local business website, and i want to rank this website for our main KW. So the idea is to rank the main Keyword to the home page www.sitename.com At the same time we blog every week and one of the categories is the same has the main Keyword. It makes sense because the majority of the blog posts are about it. In a certain way the homepage and the category page are competing for the same keyword. How can i approach this problem? Should i use rel canonical in the category page, pointing to the homepage? Thanks for your help.

How much to change to avoid duplicate content?
Working on a site for a dentist. They have a long list of services that they want us to flesh out with text. They provided a bullet list of services, we're trying to get 1 to 2 paragraphs of text for each. Obviously, we're not going to write this off the top of our heads. We're pulling text from other sources and trying to rework. The question is, how much rephrasing do we have to do to avoid a duplicate content penalty? Do we make sure there are changes per paragraph, sentence, or phrase? Thanks! Eric

Crawl Errors and Duplicate Content
SEOmoz's crawl tool is telling me that I have duplicate content at "www.mydomain.com/pricing" and at "www.mydomain.com/pricing.aspx". Do you think this is just a glitch in the crawl tool (because obviously these two URL's are the same page rather than two separate ones) or do you think this is actually an error I need to worry about? Is so, how do I fix it?
