Syndication: Link back vs. Rel Canonical
-
For content syndication, let's say I have the choice of (1) a link back or (2) a cross domain rel canonical to the original page, which one would you choose and why? (I'm trying to pick the best option to save dev time!)
I'm also curious to know what would be the difference in SERPs between the link back & the canonical solution for the original publisher and for sydication partners? (I would prefer not having the syndication partners disappeared entirely from SERPs, I just want to make sure I'm first!)
A side question: What's the difference in real life between the Google source attribution tag & the cross domain rel canonical tag?
Thanks!
PS: Don't know if it helps but note that we can syndicate 1 article to multiple syndication partners (It would't be impossible to see 1 article syndicated to 50 partners)

This is my opinion and is not backed up by any concrete evidence.
Given the choice, I would opt for the cross-domain rel canonical. Matt Cuts has said that google prioritizes the original page in search results (link references rel canonical within domain, not cross-domain) and based on todays whiteboard friday and this video from matt cuts, I think rel canonical is the way things are moving, particularly for content syndication.
Edit: It also just occurred to me that there is no reason you can't ask for both. Rel canonical is helpful to GoogleBot determining who the original content creator is but offers absolutely nothing for the user. It takes little more than the flick of a pen to require your syndication partners to include both rel canonical and a link back.
Edit #2 : Regarding your question about the difference between the Google Source Attribution tag vs. Cross-Domain rel canonical :
Update 2/11/11:
We've had a lot of interest in these meta tags, particularly in how the syndication-source tag relates to rel=canonical. After evaluating this feedback, we’ve updated our system to use rel=canonical instead of syndication-source, if both are specified.
If you know the full URL, rel=canonical is preferred, and you need not specify syndication-source.
If you know a partial URL, or just the domain name, continue using syndication-source.
We've also had people ask "why metatag instead of linktag"? We actually support both forms for the tag, and you can use either. However, we believe the linktag form is more in line with the spirit of the standard, and encourage new users to implement the linktag form rather than the metatag form we originally proposed.

Broken canonical link errors
Hello, Several tools I'm using are returning errors due to "broken canonical links". However, I'm not too sure why is that. Eg.

Page URL: domain.com/page.html?xxxx
Canonical link URL: domain.com/page.html
Returns an error. Any idea why? Am I doing it wrong? Thanks,

Rel=Canonical For Landing Pages
We have PPC landing pages that are also ranking in organic search. We've decided to create new landing pages that have been improved to rank better in natural search. The PPC team however wants to use their original landing pages so we are unable to 301 these pages to the new pages being created. We need to block the old PPC pages from search. Any idea if we can use rel=canonical? The difference between old PPC page and new landing page is much more content to support keyword targeting and provide value to users. Google says it's OK to use rel=canonical if pages are similar but not sure if this applies to us. The old PPC pages have 1 paragraph of content followed by featured products for sale. The new pages have 4-5 paragraphs of content and many more products for sale. The other option would be to add meta noindex to the old PPC landing pages. Curious as to what you guys think. Thanks.

Canonical homepage link uses trailing slash while default homepage uses no trailing slash, will this be an issue?
Hello, 1st off, let me explain my client in this case uses BigCommerce, and I don't have access to the backend like most other situations. So I have to rely on BG to handle certain issues. I'm curious if there is much of a difference using domain.com/ as the canonical url while BG currently is redirecting our domain to domain.com. I've been using domain.com/ consistently for the last 6 months, and since we switches stores on Friday, this issue has popped up and has me a bit worried that we'll loose somehow via link juice or overall indexing since this could confuse crawlers. Now some say that the domain url is fine using / or not, as per - https://moz.com/community/q/trailing-slash-and-rel-canonical But I also wanted to see what you all felt about this. What says you?

Rel=canonical on Godaddy Website builder
Hey crew! First off this is a last resort asking this question here. Godaddy has not been able to help so I need my Moz Fam on this one. So common problem My crawl report is showing I have duplicate home pages www.answer2cancer.org and www.answer2cancer.org/home.html I understand this is a common issue with apache webservers which is why the wonderful rel=canonical tag was created! I don't want to go through the hassle of a 301 redirect of course for such a simple issue. Now here's the issue. Godaddy website builder does not make any sense to me. In wordpress I could just go add the tag to the head in the back end. But no such thing exist in godaddy. You have to do this weird drag and drop html block and drag it somewhere on the site and plug in the code. I think putting before the code instead of just putting it in there. So I did that but when I publish and inspect in chrome I cannot see the tag in the head! This is confusing I know. the guy at godaddy didn't stand a chance lol. Anyway much love for any replies!

301 redirect: canonical or non canonical?
Hi, Newbie alert! I need to set up 301 redirects for changed URLs on a database driven site that is to be redeveloped shortly. The current site uses canonical header tags. The new site will also use canonical tags. Should the 301 redirects map the canonical URL on the old site to the corresponding canonical for the new design . . . or should they map the non canonical database URLs old and new? Given that the purpose of canonicals is to indicate our preferred URL, then my guess is that's what I should use. However, how can I be sure that Google (for example) has indexed the canonical in every case? Thx in anticipation.

Magento Dublicate Content (Noindex and Rel"canonical")
Hi All, Just looking for some advice regarding my website on magento. We by mistake didnt enable canonical tags and noindex tags so had a big problem with dublicate content from filter pages but also have URLs to Cats as Yes so this didnt help with not having canonical tags enabled. We now have everything enabled for a few weeks now but dont see much drop in indexed pages in google. (currently 27k and we have only 5k products) My question basically is how do we speed up noindexation of dublicate content and also would you change URL to cats as No so google just now sees the url to products? (my concerns with this is would leaving it to Yes help because it will hopefully read the canonical tags on products now) Thank you in advance Michael

Is link cloaking bad?
I have a couple of affiliate gaming sites and have been cloaking the links, the reason I do this is to stop have so many external links on my sites. In the robot.txt I tell the bots not to index my cloaked links. Is this bad, or doesnt it really matter? Thanks for your help.
