Canonicalisation - different languages and channels
-
Hi
If the same content is placed on different URL's for the purposes of providing information on different channels (i.e mobiles), or has been translated into a different language (but is still the same content), do the serach engines still count this as duplicate content and will a canonical URL have to be tagged in these instances?
Thanks in advance for your assistance.

The problem with serving content for different channels is that crawlers read 2 pieces of the same content and can penalize you. There a few workarounds for that.One is obviously the fact that you can add a rel=canonical tag, but if you are serving same content due to only channels, it may pose an issue.
Example: if your webpage URL is www.mywebsite.com/abc (which can be accessed via navigational links on your website) and you have a url www.mywebsite.com/xyz which you use for mobiles, PPC or any other channel, but both having the same content, it will cause problems.
The way to deal with such issues is adding parameters (campaign id, etc) to 1 URL to tell google that you are using this version of the page(the one with campaign id) for some specific channel.
If you are making your website ready for the mobile, the best way is to tackle is to write device detection codes in your htaccess file.
It may look something like this:
RewriteCond %{HTTP_USER_AGENT} ^.iPad.$
RewriteRule ^(.*)$ http://ipad.mydomain.com [R=301]
If you are serving content in different languages, then it shouldnt be much of a problem (generally speaking)

Hi - in general, yes, it's best to use something like the rel=canonical tag (http://www.seomoz.org/blog/canonical-url-tag-the-most-important-advancement-in-seo-practices-since-sitemaps) or to specifically tag mobile content as such - http://searchengineland.com/dont-penalize-yourself-mobile-sites-are-not-duplicate-content-40380
If it's translated to different languages, you're in the clear - that's considered substantively unique content and not subject to duplicate filtering (at least, 99% of the time).
Happy to help - great to have you in PRO!

Hreflang for multple countries but single language
I'm working on a site that has implemented hreflang. The site is all in English but has slight differences and breaks down to separate domains, so example.co.uk example.eu example.com the hreflang implementation targets specific countries per domain. This was tested using http://flang.dejanseo.com.au but Webmaster Tools has thrown up errors. For example, **URLs for your site and alternative URLs in 'en_GB' that do not have return tags. **But every page refers back.Any ideas what's going wrong?

Using the same domain for two websites (for different geographical locations)
Hi all, My client has a new E-commerce site coming out in few months.
Technical SEO | | skifr
His requirement is to use the same domain (lets call it www.domain.com for now) for two seperate websites:
The first site, for users with ip addresses from USA - which will include prices in US dollars.
The second site - for users outside of the US - will not include any prices, and will have different pages and design. Now, lets say that googlebot crawls the websites from different ip ranges. How can i make sure a user from France, for example, won't see crawled pages from the US? Sure, once he will click the result, I can redirect him to a "Sorry, but this content is unavailable in your country" page. The problem is, I don't want a user from France to see the in the search results the meta description snippets of pages related only to users in the US (in some cases, the snippets may include the prices in $).
Is Geotargeting through Webmaster Tools can help in this case? I know I can target a part of the website for a specific country (e.g. - www.domain.com/us/), but how can I make sure global users won't see the pages targeted only to the US in the search results? Thanks in Advance0 -
Will same language different region (US/UK) geotargeting via subdirectory (& GWT) cause dupe content or other issues ?
If a UK hosted site on a .com, needs to target US now too but for keywords that are spelt differently in US is creating duplicate version of uk hosted .com site and putting it on a subdirectory .com/us/ and geotargeting via webmaster tools (to usa) ok ? I take it in this scenario no dupe content issues (or other issues) so long as is geotargeted via GWT ? Or are there ? Comments from anyone with experience doing similar (same language, different region geo-targeting dupe content with kw spelling being only difference, via a subdirectory or other route) much appreciated ? Many Thanks 🙂

Best way to handle different views of the same page?
Say I have a page: mydomain.com/page But I also have different views: /?sort=alpha /print-version /?session_ID=2892 etc. All same content, more or less. Should the subsequent pages have ROBOTS meta tag with noindex? Should I use canonical? Both? Thanks!

Language/country redirect best practice?
Hi, What is SEO best practice when it comes to redirecting users from www.domain.com to their specific language/country, let's say www.domain.com/de for Germany? From what I heard in on of the whiteboard fridays, it seems to be Javascript based on IP and browser language, and then set a cookie - correct? Or should we let our users manually select their language/country at the first visit? Any suggestion appreciated, thanks!

Switching to another CMS with different permalink structure, how not to lose organic traffic and Google rankings? Urgent Please!
One of my customers is in online jewellery sales business and they are going to change their CMS; the problem is there is no co-relation between URL permalink structure of the current CMS and the new one. What should we do so that we don’t lose our current organic traffic (also Google rankings) coming from indexed URLs in Google due to permalink structure change ? Typical example: Current URL: http://www.abc.com/pirlanta-nedir,AR-3.html The new URL is going to look like this: http://www.abc.com/tek-tas-pirlanta-ar-4.html
