How far can I push rel=canonical?
-
My plan: 3 sites with identical content, yet--wait for it--for every article whose topic is A, the pages on all three sites posting that article will have a rel=canonical tag pointing to Site A. For every article whose topic is B, the pages on all three sites posting that article will have a rel=canonical tag pointing to Site B.
So Site A will have some articles about topics A, B, and C. And for pages with articles about A, the rel=canonical will point to the page it's on. Yet for pages with articles about B, the rel=canonical will point to the version of that article on site B. Etc.
I have my reasons for planning this, but you can see more or less that I want each site to rank for its niche, yet I want the users at each site to have access to the full spectrum of articles in the shared articles database without having to leave a given site.
These would be distinct brands with distinct Whois, directory listings, etc. etc.
The content is quality and unique to our company.

I think I'd start slowly in that case. Keep the relationship aspect in mind, too. Even if all three companies know the writer/client and are aware of the relationship, sooner or later one of these articles is going to take off. If one site gets the SEO credit and the other two sites aren't ranking, there may be friction. Even if the work is spread out evenly and all high-quality, you don't control (ultimately) what content finally sticks and is successful. I just think things could get weird all-around if you send every article three places and only one gets credit.

These are technically different companies with different products, all of which are in the securities industry. They are each founded by different groups of individuals, however my client is common among them and happens to be a fantastic writer. Many of the articles would add value to the readers of some of the other sites. I am hoping to develop a common command center so that in the editor for a given article he is able to just check off which of his sites the article will be published at, and which is to be considered canonical. So the sites will have different aesthetics and navigation, product pages, and other company-specific content, and not every article will show up on every site, however many will show up at multiple sites.
The idea of phasing in common articles with the cross-domain canonical strikes me as wise, and then just noindexing the non-canonical versions if I run into trouble.
-
Ah, understood. So, yes, in theory cross-domain canonical does handle this. I know major newspapers that use it for true syndication. There is risk, though, depending on the sites and content, and there is a chance Google will ignore it (moreso than in-domain canonical). So, I mostly wanted you to be aware of those risks.
META NOINDEX is safer, in some respects (Google is more likely to honor it), but if people start linking to multiple versions of the content, then you may lose the value of those inbound links on the NOINDEX'ed content. Since it's not showing up in search results, that's less likely (in other words, people are going to be most inclined to link to the canonical version), but it's a consideration.
It's really tough to give a recommendation without understanding the business model, but if you absolutely have to have separate sites and you feel that this content is valuable to the visitors of all three sites, then cross-domain canonical is an option. It's just not risk-free. Personally, I'd probably start with unique content across the three domains, then phase in the most useful pieces as duplicates with canonical. Measure and see how it goes. Don't launch 1,000 duplicates on three sites in one day.

Budget not an issue, although skilled labor is.

Very helpful, thank you!
There is in fact a legal reason why the sites must be distinct from each other and strong marketing reasons why we do need more than one site.
I should mention that although the pages hosting the shared articles will be 99% identical, each site will have other content distinct from the others.
I am open to dropping my idea to share an article database between the sites and just having unique content on each, although I have to wonder what the use of cross-domain canonical is, if not to support this kind of article syndication.
-
Completely agree with dr Peter. If you really need to separate those domains it should be a really good reason.
In my past I used to have many EMD domain to get easy traffic thanks to the domain name boost in serps and so those sites were ranking without many efforts, but after google heading more towards brands this kind of strategy is really time and money consuming.
It really depends on how much budget you may spend on those sites, but normally consolidating the value in one bigger site is the best way to build a brand and achieve links and ranks nowadays.
-
I tend to agree - you always run the risk with cross-domain canonical that Google might not honor it, and the you've got a major duplicate content problem on your hands.
I think there's a simpler reason, in most cases, though. Three unique sites/brands take 3X (or more, in practice) the time and energy to promote, build links to, build social accounts for, etc. That split effort, especially on the SEO side, can far outweigh the brand benefits, unless you have solid resources to invest (read that "$$$").
To be fair, I don't know your strategy/niche, but I've just found that to be true 95% of the time in these cases. Most of the time, I think building sub-brands on sub-folders within the main site and only having one of each product page is a better bet. The other advantage is that users can see the larger brand (it lends credibility) and can move between brands if one isn't a good match.
The exception would be if there's some clear legal or competitive reason the brands can't be publicly associated. In most cases, though, that's going to come with a lot of headaches.

Hi all, I think that your alternatives would be:
- one big site with all the thematics. In that way all users can access all content without leaving the site, no need for noindex no need for canonicals since you won't have dupe content
- three sites with specialized articles in each one. You may change slightly your design to give the user the feeling that the site is different but in the same network. Then you may interlink those sites as useful resources. Not optimal since they'll have a huge interlinking,
- as you said noindex the non canonical article. Remember that the noindex tag will prevent indexation not crawling because google will need to crawl your page to know that it should not index it. So you may add meta "noindex,nocache,follow" in the header and be sure that the juice is still flowing in your site.
-
Hmm, ok that's helpful.
The content would be identical with the possible exceptions of a very slightly different meta title and site footer.
What's my alternative to a setup like this? One site, one brand? Noindex the non-canonical article versions?
What I dislike about noindex is that it means inbound links to the non-canonical article versions bring me no benefit.
-
I believe you are playing with fire here... to me this looks like you are trying to manipulate search engines.
If you read the article About rel="canonical" on Google Webmasters Support, you will see they say rel="canonical" link element is seen as a hint and not an absolute directive
Also in the same article they specify that rel="canonical" should be used on pages with identical content. Are you sure in your case the pages have identical content (per total) or just identical articles?

Best Strategy for FAQ & Canonical?
I have an FAQ database setup on my site and there's about 30 questions in 6 categories so 5 questions per category which is a pretty good page size for one category. I'm trying to determine the best strategy for publishing them from both a user and SEO standpoint. From a user standpoint, I want to have one page per category. Dumping them into a page with all 30 questions is not user-friendly and some categories are very unrelated to others. I should note that Google did already index a page that does have all the questions on it, but I was just planning on changing that page to just have 6 links to each of the category pages so then I don't have to bother with 301 redirect or removing the pages in the site's Search Console. There's also an option to to link the questions for the entire FAQ or from the category list to one page with just that question and answer. So my thinking at this point is to as I said, just change the page that has all 30 questions to a list of the categories and link to category pages having the questions for that category and disable the individual question pages. Or would it be beneficial from an SEO page to have google index the individual question pages and link back to the category page and put a canonical tag on the category pages? In other words the question then becomes, index the category pages or index the individual question pages? The other issue is the answers for some of the questions are lengthy, multiple paragraphs, and the FAQ has the option to have a hide/unhide feature on the answers so you can easily see all the questions first then expand the answers on the ones you are interested in. However I thought I heard Google discounts (doesn't ignore) content that is by default hidden on page load. I guess this would then give a reason for going with the indexing of the individual question pages. But it seems to me, you can't put the canonical tag on the category pages and point it to the individual question page. And if you put the canonical tag on the individual question page linking it to the category page, then the individual page won't necessarily get indexed will it?

Canonical tags for duplicate listings
Hi there, We are restructuring a website. The website originally lists jobs that will have duplicate content. We have tried to ask the client not to use duplicates but apparently their industry is not something they can control. The recommendations I had is to have categories (which will have the idea description for a group of jobs), and the job listing pages. The job listing pages will then have canonical tags pointing to the category page as the primary URL to be indexed. Another opinion came from a third party that this can be seen as if we are tricking Google and would get penalised, **Is that even true? **Why would Google penalise for this if thats their recommendations in the first place? This third party suggested using nofollow on the links to these listings, or even not not index them all together. What are your thoughts? Thanks Issa

How can I optimize pages in an index stack
I have created an index stack. My home page is http://www.southernwhitewater.com My home page (if your look at it through moz bat for chrome bar} incorporates all the pages in the index. Is this Bad? I would prefer to index each page separately. As per my site index in the footer What is the best way to optimize all these pages individually and still have the customers arrive at the top and links directed to the home page ( which is actually the 1st page). I feel I am going to need a rel=coniacal might be needed somewhere. Any help would be great!!

Should I put rel=publisher on UGC?
My website has a main section that we call expert content and write for. We also have a community subdomain which is all user generated. We are a pretty big brand and I am wondering should the rel publisher tag just be for the www expert content, or should we also use it on the community UGC even though we don't directly write that?

Canonical tags required when redirecting?
Hello, My client bought a new domain and he wants it to be the main domain of his company. His current domain though has been online for 10 years and ranks pretty well on a few keywords. I feel it is necessary to redirect the old domain to the new one to take advantage of its ranking and avoid any broken links. The sites are exactly the same. Same sections and same content. Is it necessary to place canonical tags on one of the sites to avoid duplicate content/sites? Any thoughts? Thanks

Can videos be considered duplicate content?
I have a page that ranks 5 and to get a rich snippet I'm thinking of adding a relevant video to the page. Thing is, the video is already on another page which ranks for this keyword... but only at position 20. As it happens the page the video is on is the more important page for other keywords, so I won't remove it. Will having the same video on two pages be considered a duplicate?

Can Linking Between Your Own Sites Excessively Be a Penguin No-No?
I have a bunch of travel-related sites that for a long time dominated google.com.au without any intensive SEO whatsoever. Aside from solid on-page content and meta tag, I did no link building. However, all of my sites are heavily interlinked, and I think they are linked with do follow links and lots of anchor texts. Here are a few of them: www.beautifulpacific.com www.beautifulfiji.com www.beautifulcooklands.com My idea in inter-linking them was to create a kind of branded "Beautiful" nexus of sites. However, when Penguin hit -- which I believe was on April 27th -- search traffic crashed, and has crashed over and over again. I've read that Penguin penalized over-optimization vis a vis anchor text links. I don't have a lot of inbound links like these, but they are everywhere among my sites. Is it possible that all of my text links have hurt me with Penguin? Thanks to everyone in advance for your time and attention. I really appreciate it. -Mike
