Using canonical for duplicate contents outside of my domain
-
I have 2 domains for the same company, example.com and example.sg
Sometimes we have to post the same content or event on both websites so to protect my website from duplicate content plenty i use canonical tag to point to either .com or .sg depend on the page.
Any idea if this is the right decision
Thanks

Unfortunately, that's a lot more tricky. If you're trying to rank both the .com and .sg version for, let's say, US residents, and those sites have duplicate content, then you do run the risk of Google filtering one of them out. If you use canonical tags or something like that, then one site will be taken out of contention for ranking - in that case, you won't rank for both sites on the same term. The only way to have your cake and eat it too is to make the sites as unique as possible.
Even then, you're potentially going to duplicate effort and cannibalize your own rankings, so it's a risky proposition. In some cases, it may be better to try to promote your social profiles and other pages outside of your site that have some authority. It doesn't have to be your own site ranking, just a site that's generally positive or neutral.

Thanks Peter you answer has enrich the discussion
I think your suggestion is the proper way for different local domains versions of the same company or blog
My case is little different that actually lately i am trying to rank both of them in the seek of reputation management
It wasn't intended to be like that on the beginning but now we are trying to take advantage of our other local domain like .sg , .ch and .ae

Do you want the .sg site to only rank regionally in Singapore? You could use rel=alternate hreflang to designate the language/region for the two sites, and help Google more accurately know when to display which sites. This also acts as a soft canonicalization signal and tells Google that the pages are known duplicates:
-
Here's an article about rel=canonical where Dr. Pete answers some rel=canonical questions. With regards to rel=canonical passing PageRank he says:
"This is very difficult to measure, but if you use rel=canonical appropriately, and if Google honors it, then it appears to act similarly to a 301-redirect. We suspect it passes authority/PageRank for links to the non-canonical URL, with some small amount of loss (similar to a 301)."
http://moz.com/blog/rel-confused-answers-to-your-rel-canonical-questions
At the end of the following Matt Cutts video (2:10), he says that there isn't a lot of difference between the page rank passing via rel=canonical and page rank passing a 301 redirect.
http://www.youtube.com/watch?v=zW5UL3lzBOA
When it comes to the content of the page, yes, the two versions of the page should be pretty close to identical. I've seen Google refer to it as "highly similar". Here's what Google says:
"A large portion of the duplicate page’s content should be present on the canonical version. One test is to imagine you don’t understand the language of the content—if you placed the duplicate side-by-side with the canonical, does a very large percentage of the words of the duplicate page appear on the canonical page? If you need to speak the language to understand that the pages are similar; for example, if they’re only topically similar but not extremely close in exact words, the canonical designation might be disregarded by search engines."
See: http://googlewebmastercentral.blogspot.co.uk/2013/04/5-common-mistakes-with-relcanonical.html
So, if your pages are too dissimilar then Google may ignore the rel-canonical "suggestion" and the "wrong page" or both pages may appear in Google's index.

i think this is useful resource that answer a lot of questions around canonical

Thanks Doug for your useful response
Just i need to clarify your sentence
"Be aware that the value of any inbound links to that article will be allocated to the canonical version. "
Do you mean canonical link is passing the page rank similar to 301 Redirect?
What if the 2 pages wasnt 100% identical ?

Yes, this sounds absolutely correct.
You can check it's working by doing a search for some unique content in your article or using the query with the article's title:
site:{domain} "title"
If everything is working correctly you should only see the canonical version of the article in Google's index. (you can also use the inurl: to check too.
Be aware that the value of any inbound links to that article will be allocated to the canonical version. (This doesn't apply to social follows/likes though.) So think carefully about the audience for the article before deciding which version is canonical.
It may not apply in your case, but it can be a good idea to think about your readers too. By adding a link in the article to the other site, you can help to cross-promote them. You may find tat if some of your visitors find your cross posted article relevant and useful to them they may be more interested in other article on the source site.

Shopify Duplicate Content in products
Hello Moz Community, New to Moz and looking forward to beginning my journey towards SEO education and improving our clients' sites. Our client's website is a Shopify store. https://spiritsofthewestcoast.com/ Our first Moz reports show 686 duplicate content issues. I will show the first 4 as examples. https://spiritsofthewestcoast.com/collections/native-earrings-and-studs-in-silver-and-gold/products/haida-eagle-teardrop-earrings https://spiritsofthewestcoast.com/collections/native-earrings-and-studs-in-silver-and-gold/products/haida-orca-silver-earrings https://spiritsofthewestcoast.com/collections/native-earrings-and-studs-in-silver-and-gold/products/silver-oval-earrings https://spiritsofthewestcoast.com/collections/native-earrings-and-studs-in-silver-and-gold/products/haida-eagle-spirit-silver-earrings As you can see, URL titles are unique. But I know that the content in each of those products have very similar product descriptions but not exactly. But since they have been flagged as a site issue by Moz, I am guessing that the content is 95% duplicate. So can a rel=canonical be the right solution for this type of duplicate content? Or should I be considering adding new content to each of 686 products to drop below the 95% threshold? Or another solution that I may not be aware of. Thanks in advance for your assistance and expertise! Sean

Duplicate content pages on different domains, best practice?
Hi, We are running directory sites on different domains of different countries (we have the country name in the domain name of each site) and we have the same static page on each one, well, we have more of them but I would like to exemplify one static page for the sake of simplicity. So we have http://firstcountry.com/faq.html, http://secondcountry.com/faq.html and so on for 6-7 sites, faq.html from one country and the other have 94% similarity when checked against duplicate content. We would like an alternative approach to canonical cause the content couldn´t belong to only one of this sites, it belongs to all. Second option would be unindex all but one country. It´s syndicated content but we cannot link back to the source cause there is none. Thanks for taking the time in reading this.

Thin/Duplicate Content
Hi Guys, So here's the deal, my team and I just acquired a new site using some questionable tactics. Only about 5% of the entire site is actually written by humans the rest of the 40k + (and is increasing by 1-2k auto gen pages a day)pages are all autogen + thin content. I'm trying to convince the powers that be that we cannot continue to do this. Now i'm aware of the issue but my question is what is the best way to deal with this. Should I noindex these pages at the directory level? Should I 301 them to the most relevant section where actual valuable content exists. So far it doesn't seem like Google has caught on to this yet and I want to fix the issue while not raising any more red flags in the process. Thanks!

Duplicate content handling.
Hi all, I have a site that has a great deal of duplicate content because my clients list the same content on a few of my competitors sites. You can see an example of the page here: http://tinyurl.com/62wghs5 As you can see the search results are on the right. A majority of these results will also appear on my competitors sites. My homepage does not seem to want to pass link juice to these pages. Is it because of the high level of Dup Content or is it because of the large amount of links on the page? Would it be better to hide the content from the results in a nofollowed iframe to reduce duplicate contents visibilty while at the same time increasing unique content with articles, guides etc? or can the two exist together on a page and still allow link juice to be passed to the site. My PR is 3 but I can't seem to get any of my internal pages(except a couple of pages that appear in my navigation menu) to budge of the PR0 mark even if they are only one click from the homepage.
