Canonical vs Alternate for country based subdomain dupe content?
-
What's the correct method for tagging dupe content between country based subdomains?
We have:
mydomain.com // default, en-us
www.mydomain.com // en-us
uk.mydomain.com // uk, en-gb
au.mydomain.com // australia, en-au
eu.mydomain.com // europe, en-eu
In the header of each we currently have rel="alternate" tags but we're still getting dupe content warnings in Moz for the "WWW" subdomain.
Question 1) Are we headed in the right direction with using alternate? Or would it be better to use canonical since the languages are technically all English, just different regions. The content is pretty much the same minus currency and localization differences.
Question 2) How can we solve the dupe content between WWW and the base domain, since the above isn't working.
Thanks so much

Yes.

Thanks.
So then I am safe when including all of these on every subdomain?
I have a common header where the above is the exact same for every subdomain (all 4 are always included), which I assume is the correct way?
Also: Why doesn't Moz look at the hreflang tag? I'm very worried about just "ignoring" what the tool says... why is the top SEO tool in the world not capable of correctly detecting dupe content? I'm not sure I'm comfortable with just ignoring the check engine light, so to speak.

In cases like yours, using the hreflang is the correct way to handle the duplicate content issue, because of the characteristics you yourself cite: currency and localization, which may be tiny differences in terms of "content" but huge in terms of usability and making completely different a product page from another.
Remember that if you canonicalize all the "duplicate" toward the canonical, the canonicalized URLs won't be shown in the countries you're targeting with those URLs... so screwing up the international SEO strategy 100%, so each URL must have as canonical its own URL (self referential), apart the obvious canonicalization rules being applied (e.g.: url with parameter canonicalized to url without parameter).
In case the URL is canonicalized for whatever reason, remember to indicate the canonical URLs in the href of the hreflang annotations. On the contrary Google will start alerting of no-return URLs errors.
Regarding the Moz Pro crawler... don't pay attention to it, because it doesn't consider the hreflang annotation,therefore it will continue saying that those pages are duplicate.

Duplicate content
Hello mozzers, I have an unusual question. I've created a page that I am fully aware that it is near 100% duplicate content. It quotes the law, so it's not changeable. The page is very linkable in my niche. Is there a way I can build quality links to it that benefit my overall websites DA (i'm not bothered about the linkable page being ranked) without risking panda/dupe content issues? Thanks, Peter

Duplicate Content Brainstorming
Hi, New here in the SEO world. Excellent resources here. We have an ecommerce website that sells presentation templates. Today our templates come in 3 flavours - for PowerPoint, for Keynote and both - called Presentation Templates. So we've ended up with 3 URLS with similar content. Same screenshots, similar description.. Example: https://www.improvepresentation.com/keynote-templates/social-media-keynote-template https://www.improvepresentation.com/powerpoint-templates/social-media-powerpoint-template https://www.improvepresentation.com/presentation-templates/social-media-presentation-template I know what you're thinking. Why not make a website with a template and give 3 download options right? But what about https://www.improvepresentation.com/powerpoint-templates/ https://www.improvepresentation.com/keynote-templates/ These are powerfull URL's in my opinion taking into account that the strongest keyword in our field is "powerpoint templates" How would you solve this "problem" or maybe there is no problem at all.

Does duplicate content not concern Rand?
Hello all, I'm a new SEOer and I'm currently trying to navigate the layman's minefield that is trying to understand duplicate content issues in as best I can. I'm working on a website at the moment where there's a duplicate content issue with blog archives/categories/tags etc. I was planning to beat this by implementing a noindex meta tag on those pages where there are duplicate content issues. Before I go ahead with this I thought: "Hey, these Moz guys seem to know what they're doing! What would Rand do?" Blogs on the website in question appear in full and in date order relating to the tag/category/what-have-you creating the duplicate content problem. Much like Rand's blog here at Moz - I thought I'd have a look at the source code to see how it was dealt with. My amateur eyes could find nothing to help answer this question: E.g. Both the following URLs appear in SERPs (using site:moz,com and very targeted keywords, but they're there): https://moz.com/rand/does-making-a-website-mobile-friendly-have-a-universally-positive-impact-on-mobile-traffic/ https://moz.com/rand/category/moz/ Both pages have a rel="canonical" pointing to themselves. I can understand why he wouldn't be fussed about the category not ranking, but the blog? Is this not having a negative effect? I'm just a little confused as there are so many conflicting "best practice" tips out there - and now after digging around in the source code on Rand's blog I'm more confused than ever! Any help much appreciated, Thanks

Invert canonicals?
Hi, We have 2 sites, site A and site B. For now, some of our articles are duplicated on site B with rel canonicals towards site A. Starting now, Site B will be the main site for this category, we'll only post the content on this site. We will keep the old content on site A. But what do you think will happen if we invert the canonicals for the old articles? They would go towards site B. Would google eventually update its index, a bit like it would do for a redirect? Thanks !

Duplicate Content Problems
Hi I am new to the seomoz community I have been browsing for a while now. I put my new website into the seomoz dashboard and out of 250 crawls I have 120 errors! So the main problem is duplicate content. We are a website that finds free content sources for popular songs/artists. While seo is not our main focus for driving traffic I wanted to spend a little time to make sure our site is up to standards. With that said you can see when two songs by an artist are loaded. http://viromusic.com/song/125642 & http://viromusic.com/song/5433265 seomoz is saying that it is duplicate content even though they are two completely different songs. I am not exactly sure what to do about this situation. We will be adding more content to our site such as a blog, artist biographies and commenting maybe this will help? Although if someone was playing multiple bob marley songs the biography that is loaded will also be the same for both songs. Also when a playlist is loaded http://viromusic.com/playlist/sldvjg on the larger playlists im getting an error for to many links on the page. (some of the playlists have over 100 songs) any suggestions? Thanks in advance and any tips or suggestions for my new site would be greatly appreciated!

Dealing with duplicate content
Manufacturer product website (product.com) has an associated direct online store (buyproduct.com). the online store has much duplicate content such as product detail pages and key article pages such as technical/scientific data is duplicated on both sites. What are some ways to lessen the duplicate content here? product.com ranks #1 for several key keywords so penalties can't be too bad and buyproduct.com is moving its way up the SERPS for similar terms. Ideally I'd like to combine the sites into one, but not in the budget right away. Any thoughts?
