Canonical cross domain Linkjuice
-
I know that back few years ago, rel=canonical used on cross-domain was passing link juice. As I've read based on many experts (case studies), the canonical cross-domain was working like implementing a 301.
Is it still the case ? Does anyone tried to implement it recently and it worked ?

I do have duplucate content (products) on my new platform and I wonder if putting all the links of those products on Canonical could benefit the original specialized websites.
Google has not said exactly how they treat these.
I believe that rel=canonical has become a substitute for the old method of building links by article syndication. I believe that many people are doing it at industrial scale and that google will eventually start to discount the beneifits, ignore the benefits or penalize some uses of rel=canonical.
For that reason I am staying away from rel=canonical just like I stay away from dropping links in forums, buying links, linkwheels, syndicating articles, etc. That's me being cautions and taking care of my websites.
Each person must decide what they are willing to do. You can wait until Google publishes it in their webmaster guidelines or you can stop doing something that Google might simply refer to as "manipulation" without getting specific about it. Google is specific about very few things.

Thanks EGL for your response.
Here is the situation, I have 2 websites for specific markets. The websites were doing good. I decided that it might be good to have the products of both websites on a single platform as I was seeking to focus the effort on a single website. However, after few years, I did realize that the newly created platform will never take over both specialized websites as these websites were pretty well ranked on Google
My issue is, currently, I do have duplucate content (products) on my new platform and I wonder if putting all the links of those products on Canonical could benefit the original specialized websites. The resultas on the platform is decreasing as my main focus is on the 2 websites that generates revenues.Is there any purpose on doing so ? I mean putting canonical on the platform's urls ?

Let's say we have two domains. The "source domain" where the article first appeared and the "republisher domain" where the article has been posted with rel=canonical pointing back to the "source domain".
If you use a cross-domain canonical the copy of the article on the source domain will remain in the Google index. The article on the republisher domain will not be indexed. Also, any page that links to the page of the republished article will appear in the Search Console backlinks of the source article page.
The above is information that you can verify as fact through testing.
What can not be verified is how Google counts the juice from all of those links that show up in your Search Console.
My personal opinion is that Google faithfully counted the linkjuice when rel=canonical was first suggested "by Google" for attributing the source of republished articles.
However, I currently doubt that the linkjuice from cross-domain canonicals still carries the same value. And, because some people have been using cross-domain rel=canonical at industrial scale, I am starting to believe that manipulative use of rel=canonical can result in the same problems that you would incur from building unnatural links.
I am not doing anything at industrial scale, but because of the above I am not going to use cross-domain rel=canonical in the future and have taken down some republished pages that have been in place for a couple of years.

Subdomain and Domain Linking Strategy
Here is my question for SEO. We are a mug printing company and we have a website specifically for bulk orders hosted at our main link (example.com). For the purposes of this example we will assume that we only print mugs for bands. Eg. orders for 100 mugs at a time for a band. We have had a need to create stores for bands so that they can then pass a link to their fans to purchase mugs. Our main website deals specifically with bulk orders only with customer provided logos, so extending this workflow to our main domain takes quite a bit of development time. Because of this, we purchased a service that allows us to create stores under the new domain stores.example.com. The root domain is the same as our main domain but there is “stores” in front of the domain. A band’s website that we would create would then look something like : stores.example.com/band1_merchandise These links are going to be spread by the band all over the web, and it is in my hope to be able to take advantage of this. Ideally stores.example.com/band1_merchandise being spread around will also give us a boost to www.example.com My question is how can we benefit the most from bands sharing the subdomain link such that our main website will be able to see an SEO benefit.

Sub Domain rel=canonical to Main Domain
Just a quick one, i have the following example scenario. Main Domain: http://www.test.com Sub Domain: http://sub.test.com What I am wondering is I can add onto the sub domain a rel=canonical to the main domain. I dont want to de-index the whole sub domain just a few pages are duplicated from the main site. Is it easier to de-index the individual sub domain pages or add the rel=canonical back to the main domain. Much appreciated Joseph

Two sites, heavily cross linking, targeting the same keyword - is this a battle worth fighting?
Hi Mozzers, Would appreciate your input on this, as many people have differing views on this when asked... We manage 2 websites for the same company (very different domains) - both sites are targeting the same primary keyword phrase, however, the user journey should incorporate both websites, and therefore the sites are very heavily cross linked - so we can easily pass a user from one site to another. Whilst site 1 is performing well for the target keyword phrase, site 2 isn't. Site 1 is always around 2 to 3 rank, however we've only seen site 2 reach the top of page 2 in SERPs at best, despite a great deal of white hat optimisation, and is now on the decline. There's also a trend (all be it minimal) of when site 1 improves in rank, site 2 drops. Because the 2 sites are so heavily inter-linked could Google be treating them as one site, and therefore dropping site 2 in the SERPs, as it is in Google's interests to show different, relevant sites?

Link Farms and The Relationship between 2 domain with a 301 Redirect
I have an interesting scenario: Domain A was worked on by a disreputable SEO company off shore. The owner of Domain A came to me for my assistance and evaluation on how the off shore company was doing. I concluded that he should terminate the relationship immediately. One of the bad things they did was register Domain A with a LOT of link farms. I started working on a new site that eventually we decided to go with Domain B (a better, but totally related domain name to Domain A). I added a nice new site and had my client write clean, relevant information for it. We've done all legitimate, above ground by-google's-recommendation SEO for Domain B. I have a series of 301 redirects from Domain A to Domain B. Since April 24th, organic search results have plummeted. I see many incoming links via Webmaster Tools as the massive link farms, but those link farms have Domain A in their databases, not Domain B. My question: is Domain B inheriting the link juice from Domain A insofar as the incoming links are showing up in Webmaster Tools as directly related to Domain A? Should I sever the ties with Domain A altogether? Thanks.

Redirects/What to do with multi domains for the same company?
What is the correct way to "redirect" a domain if you have multi domain names for the same site? For example if a company has www.mysite.com www.mysite.info www.mysite.tv www.mysite+location.com Say my website lived at this location www.mysite.com would I then just forward the other domains to the same place? Do search engines penilize for this? Do search engines view this as duplicated content? Is it even worth having these domains and making the active? Thanks in advance!
