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.

How can I stop a tracking link from being indexed while still passing link equity?
I have a marketing campaign landing page and it uses a tracking URL to track clicks. The tracking links look something like this: http://this-is-the-origin-url.com/clkn/http/destination-url.com/ The problem is that Google is indexing these links as pages in the SERPs. Of course when they get indexed and then clicked, they show a 400 error because the /clkn/ link doesn't represent an actual page with content on it. The tracking link is set up to instantly 301 redirect to http://destination-url.com. Right now my dev team has blocked these links from crawlers by adding Disallow: /clkn/ in the robots.txt file, however, this blocks the flow of link equity to the destination page. How can I stop these links from being indexed without blocking the flow of link equity to the destination URL?

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!

Product Variations (rel=canonical or 301) & Duplicate Product Descriptions
Hi All, Hoping for a bit of advice here please, I’ve been tasked with building an e-commerce store and all is going well so far. We decided to use Wordpress with Woocommerce as our shop plugin. I’ve been testing the CSV import option for uploading all our products and I’m a little concerned on two fronts: - Product Variations Duplicate content within the product descriptions **Product Variations: - ** We are selling furniture that has multiple variations (see list below) and as a result it creates c.50 product variations all with their own URL’s. Facing = Left, Right Leg style = Round, Straight, Queen Ann Leg colour = Black, White, Brown, Wood Matching cushion = Yes, No So my question is should I 301 re-direct the variation URL’s to the main product URL as from a user perspective they aren't used (we don't have images for each variation that would trigger the URL change, simply drop down options for the user to select the variation options) or should I add the rel canonical tag to each variation pointing back to the main product URL. **Duplicate Content: - ** We will be selling similar products e.g. A chair which comes in different fabrics and finishes, but is basically the same product. Most, if not all of the ‘long’ product descriptions are identical with only the ‘short’ product descriptions being unique. The ‘long’ product descriptions contain all the manufacturing information, leg option/colour information, graphics, dimensions, weight etc etc. I’m concerned that by having 300+ products all with identical ‘long’ descriptions its going to be seen negatively by google and effect the sites SEO. My question is will this be viewed as duplicate content? If so, are there any best practices I should be following for handling this, other than writing completely unique descriptions for each product, which would be extremely difficult given its basically the same products re-hashed. Many thanks in advance for any advice.

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.

Updating inbound links vs. 301 redirecting the page they link to
Hi everyone, I'm preparing myself for a website redesign and finding conflicting information about inbound links and 301 redirects. If I have a URL (we'll say website.com/website) that is linked to by outside sources, should I get those outside sources to update their links when I change the URL to website.com/webpage? Or is it just as effective from a link juice perspective to simply 301 redirect the old page to the new page? Are there any other implications to this choice that I may want to consider? Thanks!
