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.

Trailing slash URLs and canonical links
Hi, I've seen a fair amount of topics speaking about the difference between domain names ending with or without trailing slashes, the impact on crawlers and how it behaves with canonical links.
Technical SEO | Feb 6, 2019, 8:09 AM | GhillC
However, it sticks to domain names only.
What about subfolders and pages then? How does it behaves with those? Say I've a site structured like this:
https://www.domain.com
https://www.domain.com/page1 And for each of my pages, I've an automatic canonical link ending with a slash.
Eg. rel="canonical" href="https://www.domain.com/page1/" /> for the above page. SEM Rush flags this as a canonical error. But is it exactly?
Are all my canonical links wrong because of that slash? And as subsidiary question, both domain.com/page1 and domain.com/page1/ are accessible. Is it this a mistake or it doesn't make any difference (I've read that those are considered different pages)? Thanks!

Can I use a 301 redirect to pass 'back link' juice to a different domain?
Hi, I have a backlink from a high DA/PA Government Website pointing to www.domainA.com which I own and can setup 301 redirects on if necessary. However my www.domainA.com is not used and has no active website (but has hosting available which can 301 redirect). www.domainA.com is also contextually irrelevant to the backlink. I want the Government Website link to go to www.domainB.com - which is both the relevant site and which also should be benefiting from from the seo juice from the backlink. So far I have had no luck to get the Government Website's administrators to change the URL on the link to point to www.domainB.com. Q1: If i use a 301 redirect on www.domainA.com to redirect to www.domainB.com will most of the backlink's SEO juice still be passed on to www.domainB.com? Q2: If the answer to the above is yes - would there be benefit to taking this a step further and redirect www.domainA.com to a deeper directory on www.domianB.com which is even more relevant?

ie. redirect www.domainA.com to www.domainB.com/categoryB - passing the link juice deeper.0 -
Do Canonical Tags Pass Link Juice?
I have an ecommerce website where some pages link to a product page with a different URL. EXAMPLE: 1: /category/product1.html (not indexed by Google) with canonical pointing to product1.html Other page link to the product like below. 2: product1.html (indexed by Google) Now the question is, does 1: pass any link juice to product1.html or not? Is it worth to change everything and link only to one URL? My site is running on Magento!

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!

Rel canonical between mirrored domains
Hi all & happy new near! I'm new to SEO and could do with a spot of advice: I have a site that has several domains that mirror it (not good, I know...) So www.site.com, www.site.edu.sg, www.othersite.com all serve up the same content. I was planning to use rel="canonical" to avoid the duplication but I have a concern: Currently several of these mirrors rank - one, the .com ranks #1 on local google search for some useful keywords. the .edu.sg also shows up as #9 for a dirrerent page. In some cases I have multiple mirrors showing up on a specific serp. I would LIKE to rel canonical everything to the local edu.sg domain since this is most representative of the fact that the site is for a school in Singapore but...
Technical SEO | Jan 18, 2014, 9:07 PM | AlexSG
-The .com is listed in DMOZ (this used to be important) and none of the volunteers there ever respoded to requests to update it to the .edu.sg
-The .com ranks higher than the com.sg page for non-local search so I am guessing google has some kind of algorithm to mark down obviosly local domains in other geographic locations Any opinions on this? Should I rel canonical the .com to the .edu.sg or vice versa? I appreciate any advice or opinion before I pull the trigger and end up shooting myself in the foot! Best regards from Singapore!0 -
Correct linking to the /index of a site and subfolders: what's the best practice? link to: domain.com/ or domain.com/index.html ?
Dear all, starting with my .htaccess file: RewriteEngine On
Technical SEO | Jul 25, 2013, 6:54 PM | inlinear
RewriteCond %{HTTP_HOST} ^www.inlinear.com$ [NC]
RewriteRule ^(.*)$ http://inlinear.com/$1 [R=301,L] RewriteCond %{THE_REQUEST} ^./index.html
RewriteRule ^(.)index.html$ http://inlinear.com/ [R=301,L] 1. I redirect all URL-requests with www. to the non www-version...
2. all requests with "index.html" will be redirected to "domain.com/" My questions are: A) When linking from a page to my frontpage (home) the best practice is?: "http://domain.com/" the best and NOT: "http://domain.com/index.php" B) When linking to the index of a subfolder "http://domain.com/products/index.php" I should link also to: "http://domain.com/products/" and not put also the index.php..., right? C) When I define the canonical ULR, should I also define it just: "http://domain.com/products/" or in this case I should link to the definite file: "http://domain.com/products**/index.php**" Is A) B) the best practice? and C) ? Thanks for all replies! 🙂

Value of an embedded site vs. a direct link?
We have a new site that is a great resource for a serious subject (suicide). I have been getting many requests from various communities and clinics about help on embedding our site in their websites. Although I certainly don't want to keep this resource from being used as much as possible, I am curious about the SEO costs/benefit to having someone embed our site on their own website rather than provide a link to our website directly from theirs.

Internal search : rel=canonical vs noindex vs robots.txt
Hi everyone, I have a website with a lot of internal search results pages indexed. I'm not asking if they should be indexed or not, I know they should not according to Google's guidelines. And they make a bunch of duplicated pages so I want to solve this problem. The thing is, if I noindex them, the site is gonna lose a non-negligible chunk of traffic : nearly 13% according to google analytics !!! I thought of blocking them in robots.txt. This solution would not keep them out of the index. But the pages appearing in GG SERPS would then look empty (no title, no description), thus their CTR would plummet and I would lose a bit of traffic too... The last idea I had was to use a rel=canonical tag pointing to the original search page (that is empty, without results), but it would probably have the same effect as noindexing them, wouldn't it ? (never tried so I'm not sure of this) Of course I did some research on the subject, but each of my finding recommanded one of the 3 methods only ! One even recommanded noindex+robots.txt block which is stupid because the noindex would then be useless... Is there somebody who can tell me which option is the best to keep this traffic ? Thanks a million
