.com and .co.uk duplicate content
-
hi mozzers
I have a client that has just released a .com version of their .co.uk website. They have basically re-skinned the .co.uk version with some US amends so all the content and title tags are the same. What you do recommend? Canonical tag to the .co.uk version? rewrite titles?
-
Just a quick question, the client in question, in their wisdom, decided to put the US website live without telling me and our UK rankings have dropped significantly, do you think the tag will start to fix this?
-
It is unlikely because Google normally gives preference to the original for a fairly long period of time. However with Google there are no certainties but they do get this right in almost all cases I have seen.
The only users you should see decline on your site are non UK visitors as you are telling them with default-x that they should be sent to the .com
There are many huge companies adopting this process and also thousands of other smaller sites, I think Google has ironed out most of the issues over the last 2 years. You are more likely to see a slower uptake on the new domain than the original than the other way around.
Hope that helps

Hi Gary,
thanks for the help, as a UK website, we primarily want to rank in the UK but we obviously want to rank in the US. By making the .com website (which is brand new) is this likely to affect our UK rankings or should they be unaffected?
Thanks again,
Karl

The actual page you want to look at is https://support.google.com/webmasters/answer/189077
hreflang is the tag you should implement.
I have had long chats with John Mueller at Google about this.
Your setup should be something like this on all pages on both sites.
Within about 7 days depending on the size of your website the .com should appear in favor of the .co.uk for your US based results. For me it happened within an hour!
Setting your .com as a default will be better than setting your co.uk. The co.uk is already a region specific TLD and will not rank well generally in other search engines even if set in the hreflang to do differently.
This will let Google decide where to send traffic too based on their algo/data.
If you use a canonical tag you will be suggesting/pushing US users to the original content instead of the US site.

Ok, thanks for the help. I'll have a look into it and see what it says. The .com website is up now and they are hell bent on it staying! I did recommend having a /US but they preferred the .com!
Anyway thanks for the advice!

Hiya,
The alternative tag is a good start but you may want to do some more reading I'll put some links below. It's easier to try to make unique content or have a structure like www.example.com/us which may be an easier short term until you've got enough content for a .com site.

I always find it nicer to formulate your own answers and learn a bit along the way so I help the above helps you do that.

Thanks Chris,
So would you implement the rel=alternative href=x tag then?

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!

Duplicate content and 404 errors
I apologize in advance, but I am an SEO novice and my understanding of code is very limited. Moz has issued a lot (several hundred) of duplicate content and 404 error flags on the ecommerce site my company takes care of. For the duplicate content, some of the pages it says are duplicates don't even seem similar to me. additionally, a lot of them are static pages we embed images of size charts that we use as popups on item pages. it says these issues are high priority but how bad is this? Is this just an issue because if a page has similar content the engine spider won't know which one to index? also, what is the best way to handle these urls bringing back 404 errors? I should probably have a developer look at these issues but I wanted to ask the extremely knowledgeable Moz community before I do 🙂

Duplicate Content on a Page Due to Responsive Version
What are the implications if a web designer codes the content of the site twice into the page in order to make the site responsive? I can't add the url I'm afraid but the H1 and the content appear twice in the code in order to produce both a responsive version and a desktop version. This is a Wordpress site. Is Google clever enough to distinguish between the 2 versions and treat them individually? Or will Google really think that the content has been repeated on the same page?

Headers & Footers Count As Duplicate Content
I've read a lot of information about duplicate content across web pages and was interested in finding out about how that affected the header and footer of a website. A lot of my pages have a good amount of content, but there are some shorter articles on my website. Since my website has a header, footer, and sidebar that are static, could that hurt my ranking? My only concern is that sometimes there's more content in the header/footer/sidebar than the article itself since I have an extensive amount of navigation. Is there a way to define to Google what the header and footer is so that they don't consider it to be duplicate content?

Localized domains and duplicate content
Hey guys, In my company we are launching a new website and there's an issue it's been bothering me for a while. I'm sure you guys can help me out. I already have a website, let's say ABC.com I'm preparing a localized version of that website for the uk so we'll launch ABC.co.uk Basically the websites are going to be exactly the same with the difference of the homepage. They have a slightly different proposition. Using GeoIP I will redirect the UK traffic to ABC.co.uk and the rest of the traffic will still visit .com website. May google penalize this? The site itself it will be almost the same but the homepage. This may count as duplicate content even if I'm geo-targeting different regions so they will never overlap. Thanks in advance for you advice

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?
