Geotargeting duplicate content to different regions - href and canonical tag confusion
- 
					
					
					
					
If you duplicate content onto a sub-folder for say a new US geotargeted site (to target kw spelling differences) and, in addition to GWT geotargeting settings, implement the 'Canonical' and 'Hreflang' tags on these new pages to show G different region and language version (en-us). Then does the original/main site similar pages also need to have canonical and href tags ?
The main/original sites page I don't really want to target a specific country (although existing signals (hosting etc) will be UK (primary target of main site) but pages show up in other country searches too (which we want).
Im presuming fine to leave the original/main site as it currently is although wording in google blog/webmaster central articles etc are a bit confusing hence why im asking for anyone elses opinion/input on this.
Also is there are any benefit (or just best practice) to use 'www.example.com/en-us/...' in the subdirectory URL as opposed to just 'www.example.com/us/'
many thanks in advance to any commentators

Hi,
I suggest you both to give a read to this post by DejanSEO, which is quite clear and - IMHO - points to the right interpretation of a somehow confused best practice.

Thats what i thought originally but getting confised when i read this page: http://googlewebmastercentral.blogspot.com.au/2011/12/new-markup-for-multilingual-content.html
Specifically this bit:
Annotating pages as substantially similar content
Optionally, for pages that have substantially the same content in the same language and are targeted at multiple countries, you may use the rel="canonical" link element to specify your preferred version. We’ll use that signal to focus on that version in search, while showing the local URLs to users where appropriate. For example, you could use this if you have the same product page in German, but want to target it separately to users searching on the Google properties for Germany, Austria, and Switzerland.
And read in conjunction with this article:
Specifically this bit:
The Effect Of Combining Canonical Tags & Hreflang Tags
Not forgetting that the canonical tags should only be used with content in the same language, when would we use both?
Well firstly, the use of both would involve what I usually call world languages such as English, Spanish, French or Portuguese. These languages are used in many countries and, whilst there are variations between the use of these languages in those countries, the variations are sometimes small.
Additionally, multinational publishers often save costs by using one version of the language for all countries speaking that general language, thus ignoring the regional variations. In other words, for Spain and Mexico, Google is presented with exactly the same content, letter for letter.
The canonical acknowledges that this is the same content. The Hreflang tag identifies which URL should be displayed in different sets of results.
So, in other words, canonical + Hreflang = same content + different URL.
Google knows the content is the same, but displays the correct URL for the Google domain search (e.g. google.com.mx will see the relevant URLs for Mexico displayed in the results).

With canonical tag it is a one way road:
You have Page A and Page B with the same content but you want to point out Page A
Page B has a canonical to Page A:
Page B will disappear from the Search Results transferring all the link juice that it has gained to Page A
If you have the same content in different languages then you should use hreflang telling search engines that the two are the same but in other language:
Page A and Page B will have both the following in their headers
This way you will not Geo-Target but Language-Target the two pages ;-) - 
					
					
					
					
thanks Istvan
but what about whether its a requirement, or suggested best practice, that if you have tags (say canonical) on one set of duplicate pages then you must also add to the other similar/dupe pages (on original site).
Can you have one but not the other without it causing issues or do you need both to stop duplicate issues ?
 - 
					
					
					
					
Sorry for responding late, but I somehow forgot to answer this one.
So basically I would consider putting HREFLANG to all of the pages (US, original and any other language). Please note that HREFLANG is connected to optimizing the same content on different languages and not for geo-targeting mainly.
The best example would be Belgium. You can have content in French and in Dutch, still you are optimizing for the same region.

Thanks Itsvan, its a good answer and further information! What im really trying to establish though is if its ok to ONLY add canonical & href tags to the US focused subdirectory site ? Do they need to be added to the main site too or can I leave them off (since dont want to geotarget the main site) ? Im confused by wording on google articles/bogs etc on this subject. Since think they say that if you put the tags on a duplicate page you need to also put tags with alternative region/lang tags on the corresponding dupe content page (although i dont want to since want to leave main site free of specific geotargeting). In other words is it a technical requirement/necessity to have tags on both sets of dupe content ?

Hi danarchism,
This is what we have on a quite big website:
1. Main site is geo-targeted for a specific country
2. sub-folders of the site are geo-targeted for other countries
3. On each Page in the header we have the HREFLANG to the other 9 languages we use on the site.
Still when we talk about SERP impressions we have many times overlays (Such as the Geo-Targeted content to the Netherlands will appear in the Google.be or Geo-Targeted content to Germany appears in Google.At).
I hope this helped,
Istvan

Duplicate Content and Subdirectories
Hi there and thank you in advance for your help! I'm seeking guidance on how to structure a resources directory (white papers, webinars, etc.) while avoiding duplicate content penalties. If you go to /resources on our site, there is filter function. If you filter for webinars, the URL becomes /resources/?type=webinar We didn't want that dynamic URL to be the primary URL for webinars, so we created a new page with the URL /resources/webinar that lists all of our webinars and includes a featured webinar up top. However, the same webinar titles now appear on the /resources page and the /resources/webinar page. Will that cause duplicate content issues? P.S. Not sure if it matters, but we also changed the URLs for the individual resource pages to include the resource type. For example, one of our webinar URLs is /resources/webinar/forecasting-your-revenue Thank you!

How long does it take for canonical tags to work
How long on average does it take for a canonical tag to work? Understand that canonicals are just a suggestion, but after adding a canonical tag and submitting the page via Google fetch, assuming Google follows the canonical, would you expect it to work after a day or two or does it take longer? We added canonicals to old PPC landing pages that are ranking organically, though our new landing pages (which we want to rank organically) are not identical and have a bit more content/features. They are similar though. Canonicals were added to the old pages (pointing to new pages) and requested indexing via search console. Old pages are still ranking and new pages not so much. FYI we are unable to 301 old PPC pages due to other non negotiable reasons unfortunately. Thanks.

Does Google read dynamic canonical tags?
Does Google recognize rel=canonical tag if loaded dynamically via javascript? Here's what we're using to load: <script> //Inject canonical link into page head if (window.location.href.indexOf("/subdirname1") != -1) { canonicalLink = window.location.href.replace("/kapiolani", ""); } if (window.location.href.indexOf("/subdirname2") != -1) { canonicalLink = window.location.href.replace("/straub", ""); } if (window.location.href.indexOf("/subdirname3") != -1) { canonicalLink = window.location.href.replace("/pali-momi", ""); } if (window.location.href.indexOf("/subdirname4") != -1) { canonicalLink = window.location.href.replace("/wilcox", ""); } if (canonicalLink != window.location.href) { var link = document.createElement('link'); link.rel = 'canonical'; link.href = canonicalLink; document.head.appendChild(link); } script>

Duplicate Content Issues on Product Pages
Hi guys Just keen to gauge your opinion on a quandary that has been bugging me for a while now. I work on an ecommerce website that sells around 20,000 products. A lot of the product SKUs are exactly the same in terms of how they work and what they offer the customer. Often it is 1 variable that changes. For example, the product may be available in 200 different sizes and 2 colours (therefore 400 SKUs available to purchase). Theese SKUs have been uploaded to the website as individual entires so that the customer can purchase them, with the only difference between the listings likely to be key signifiers such as colour, size, price, part number etc. Moz has flagged these pages up as duplicate content. Now I have worked on websites long enough now to know that duplicate content is never good from an SEO perspective, but I am struggling to work out an effective way in which I can display such a large number of almost identical products without falling foul of the duplicate content issue. If you wouldnt mind sharing any ideas or approaches that have been taken by you guys that would be great!

How to prevent duplicate content at a calendar page
Hi, I've a calender page which changes every day. The main url is
Technical SEO | | GeorgFranz
/calendar For every day, there is another url: /calendar/2012/09/12
/calendar/2012/09/13
/calendar/2012/09/14 So, if the 13th september arrives, the content of the page
/calendar/2012/09/13
will be shown at
/calendar So, it's duplicate content. What to do in this situation? a) Redirect from /calendar to /calendar/2012/09/13 with 301? (but the redirect changes the day after to /calendar/2012/09/14) b) Redirect from /calendar to /calendar/2012/09/13 with 302 (but I will loose the link juice of /calendar?) c) Add a canonical tag at /calendar (which leads to /calendar/2012/09/13) - but I will loose the power of /calendar (?) - and it will change every day... Any ideas or other suggestions? Best wishes, Georg.0 - 
		
		
		
		
		
		
Duplicate Content and URL Capitalization
I have multiple URLs that SEOMoz is reporting as duplicate content. The reason is that there are characters in the URL that may, or may not, be capitalized depending on user input. A couple examples are: www.househitz.com/Pennsylvania/Houses-for-sale www.househitz.com/Pennsylvania/houses-for-sale www.househitz.com/Pennsylvania/Houses-for-rent www.househitz.com/Pennsylvania/houses-for-rent There are currently thousands of instances of this on the site. Is this something I should spend effort to try and resolve (may not be minor effort), or should I just ignore it and move on?

How much to change to avoid duplicate content?
Working on a site for a dentist. They have a long list of services that they want us to flesh out with text. They provided a bullet list of services, we're trying to get 1 to 2 paragraphs of text for each. Obviously, we're not going to write this off the top of our heads. We're pulling text from other sources and trying to rework. The question is, how much rephrasing do we have to do to avoid a duplicate content penalty? Do we make sure there are changes per paragraph, sentence, or phrase? Thanks! Eric

Should there be a canonical tag on my 404 error page?
In my crawl diagnostics, I notice some 4xx client errors. They are appearing for pages that no longer exist, so I'm not sure what the problem is. Shouldn't they just be dealt as 404's? Anyway, on closer inspection I noticed that my 404 error page contains a canonical tag which points to the missing page. Could this be the issue? Is it a good idea to remove the canonical tag from this error page? Thanks.
