Cross-Domain Canonical Showing as inbound links?
-
I run several ecommerce websites, and there is some overlap in the products offered between sites. To solve this duplicate content issue, I use a cross-domain rel canonical so that there is only 1 authoritative page per product, even if it is sold on multiple sites.
However, I am noticing that my inbound link profile is massively expanding because Google sees these as inbound links. The top linking domains for my site are all owned by me, even though there are not any actual links between the sites.
Has anyone else experienced this?

I actually like it - think it makes sense for what you're describing, and I don't think I'd change it. The other option might be a 301 redirect or simply linking to only one site, but then you'd be changing branding/domain and possibly losing the customer.

Hey Rand, thanks for the info. I did notice that OSE is counting them as links as well. Do you think this is an issue in my scenario? Would I be better off no-indexing the "duplicate" product pages on the non-primary sites?
As a fake example, imagine I sell sewing machines on one site, arts and crafts on another. There is some overlap in products between these two industries, so it makes sense to show (as an example) yarn on both sites. However since the product pages are the same, you would want to avoid duplicate content being indexed. Do you think rel canonical or noindex is a better solution?

Yeah - I've seen it to (only had a single site cross-domaining). We're actually working to count these as links in OSE/Mozscape, because that appears to be how Google treats them. My guess is that they're actually more powerful than just a link (probably pass 90-95% of a page's link juice type metrics vs. some small fraction for an individual link), but in many other ways, very similar.

Canonical URL's For Two Domains
We have two websites, one we use for Google PPC (website 1) and one (website 2) we use for everything else. The reason is we are in an industry that Google Adwords doesn't like, so we built a whole other website that removes the product descriptions as Google Adwords doesn't approve of many of them (nutrition). Right now we have that Google Adwords approved website (website 1) no-index/no-follow because we didn't want to run into potential duplicate content issues in free search, but the issue is we can't submit it to Google Shopping...as they require it to be indexable. Do you think removing the no-index/no-follow from that website 1 and adding canonical URL's pointing to website 2 would resolve this issue (being able to submit it to Google Shopping) and not cause any problems with duplicate content? I was thinking of adding the canonical tag to all pages of website 1 and point it to website 2. Does that make sense? Do you think that would work?

Using a Sub Domain as a Main Domain?
Hi, I'm working on a site at the moment and the sub domain is acting as the main domain. This occurred when the site was redesigned and built on a sub domain for testing but it was never moved to the main domain when it went live (a couple of years ago). So little or no pages are live on domain.com but all on sub.domain.com. It's a large company but they have very poor rankings. Would you recommend that they move the sub domain back into the root folder? Does this involve renaming/re-pointing URLs? Thanks Louise

Same content on other domain owned by de company. Canonical is not working
Hi! I am analyzing a website right now. It's a school, let's name it NEWSCHOOL. This school is owned by other school, let's name it, BIGSCHOOL NEWSCHOOL is specialized in tourism degrees, and the BIGSCHOOL is a bigger and older one with a lot of different degrees. What happens is that NEWSCHOOL has a course, let's name it TOURISM DEGREE.

BIGSCHOOL has that course too, with the same content, trying to help to promote the content, because this school is older, well known and has a consolidated brand internationally. BIGSCHOOL, has placed a canonical tag, telling Google that content comes from NEWSCHOOL. What is happening is that the result of newschool is beeing omited by google. The first result is the BIGSCHOOL content, and then a lot of training portals, where the degree content is too to increase its visibility. So, I would like to know, how can we do to say google that the content that it should show is the one of NEWSCHOOL and not the one in BIGSCHOOL. It's pretty clear that Google knows that those portals are closed related, because it is omitting the NEWSCHOOL results. I know that we can send a link from the content area from one portal to the other in the content we want. But... would it solve the problem... and y we have to repeat that for each degree, woudn't it be a little dangerous? Would like to know your points of view! Thanks!0 -
Cross Domain Rel Canonical tags vs. Rel Canonical Tags for internal webpages
Today I noticed that one of my colleagues was pointing rel canonical tags to a third party domain on a few specific pages on a client's website. This was a standard rel canonical tag that was written Up to this point I haven't seen too many webmasters point a rel canonical to a third party domain. However after doing some reading in the Google Webmaster Tools blog I realized that cross domain rel canonicals are indeed a viable strategy to avoid duplicate content. My question is this; should rel canonical tags be written the same way when dealing with internal duplicate content vs. external duplicate content? Would a rel=author tag be more appropriate when addressing 3rd party website duplicate content issues? Any feedback would be appreciated.

Spam Links? -115 Domains Sharing the Same IP Address, to Remove or Not Remove Links
Out of 250 domains that link to my site about 115 are from low quality directories that are published by the same company and hosted on the same ip address. Examples of these directories are: -www.keydirectory.net -www.linkwind.com -www.sitepassage.com -www.ubdaily.com -www.linkyard.org A recent site audit from a reputable SEO firm identified 125 toxic links. I assume these are those toxic links. They also identified about another 80 suspicious domains linking to my site. They audit concluded that my site is suffering a partial Penguin penalty due to low quality links. My question is whether it is safe to remove these 125 links from the low quality directories. I am concerned that removing this quantity of links all at once will cause a drop in ranking because the link profile will be thin with only about 125 domains remaining that point to the site. Granted those 125 domains should be of somewhat better quality. I am playing with fire by having these removed. I URGENTLY NEED ADVICE AS THE WEBMASTER HAS INITIATED STEPS TO REMOVE THE 125 LINKS. Thanks everyone!!! Alan

Canonical tag
Hi all, I have an ecommerce client and on the pages they have a drop down so customers can view via price, list etc. Natrurally I want a canonical tag on these pages, here's the question. as they have different pages of products, the canonical tag on http://www.thegreatgiftcompany.com/occassion/christmas#items-/occassion/christmas/page=7/?sort=price_asc,searchterm=,layout=grid,page=1 is to http://www.thegreatgiftcompany.com/occassion/christmas#items-/occassion/christmas/page=7. now, because the page=7 is a duplicate of the main page, shouldn't the canonical just be to the main page rather than page=7? Even when there is a canonical tag on the /Christmas/page=7 to the /Christmas page? hope that makes sense to everyone!

Should 301 Redirects be used only in cross domains or also internally?
In the following video with Cutts: http://youtu.be/r1lVPrYoBkA he explains a bit more about 301 redirects but he only talks about cross sites. What about redirecting internally from a non-existing product in a store to a new similar existing product?
