International SEO - cannibalisation and duplicate content
-
Hello all,
I look after (in house) 3 domains for one niche travel business across three TLDs: .com .com.au and co.uk and a fourth domain on a co.nz TLD which was recently removed from Googles index.
Symptoms:
For the past 12 months we have been experiencing canibalisation in the SERPs (namely .com.au being rendered in .com) and Panda related ranking devaluations between our .com site and com.au site.
Around 12 months ago the .com TLD was hit hard (80% drop in target KWs) by Panda (probably) and we began to action the below changes. Around 6 weeks ago our .com TLD saw big overnight increases in rankings (to date a 70% averaged increase). However, almost to the same percentage we saw in the .com TLD we suffered significant drops in our .com.au rankings. Basically Google seemed to switch its attention from .com TLD to the .com.au TLD.
Note: Each TLD is over 6 years old, we've never proactively gone after links (Penguin) and have always aimed for quality in an often spammy industry.
**Have done: **
- Adding HREF LANG markup to all pages on all domain
- Each TLD uses local vernacular e.g for the .com site is American
- Each TLD has pricing in the regional currency
- Each TLD has details of the respective local offices, the copy references the lacation, we have significant press coverage in each country like The Guardian for our .co.uk site and Sydney Morning Herlad for our Australia site
- Targeting each site to its respective market in WMT
- Each TLDs core-pages (within 3 clicks of the primary nav) are 100% unique
- We're continuing to re-write and publish unique content to each TLD on a weekly basis
- As the .co.nz site drove such little traffic re-wrting we added no-idex and the TLD has almost compelte dissapread (16% of pages remain) from the SERPs.
- XML sitemaps
- Google + profile for each TLD
**Have not done: **
- Hosted each TLD on a local server
- Around 600 pages per TLD are duplicated across all TLDs (roughly 50% of all content). These are way down the IA but still duplicated.
- Images/video sources from local servers
- Added address and contact details using SCHEMA markup
Any help, advice or just validation on this subject would be appreciated!

Hey Simon,
The Australia is lang="en-au"
The UK is lang="en-gb"
The US is lang="en-us"
We've tried to keep these as tight per country as possible so opted not to use the straight 'en'.
In analytics, there has been some reduction is language referrals, mainly "en-gb" falling from the number one language type for the US site, which is a positive. Interstingly enough, once we removed the .co.nz fro mthe Index the .com site remove in to dominate the SERPs for brand and some core-KW searches in Google.co.nz.
Its a little unfortunate as Panda, from my understanding, is keen to spare ccTLDs from any harsh devaluations, but we'll hopefully be able to hit whatever threshold for % of unique content in the near future.
We have review functionality planned for each TLD which should help add value to existing duplicate content. Once this is up and I have some more robust data I'll pull a post together for YouMoz.
Thanks for the feedback!

Wow, that's a pretty comprehensive list of actions you've compiled there and you seem to have covered pretty much all the bases. I almost think your post should be promoted on Youmoz as a great step of actions for targeting regional websites.
My experience of hreflang is that it is not perfect in that you occasionally get the wrong versions of pages served in SERPs. I wonder do you specify the .com as 'en' in the hreflang mark up in order that it is the generic English language version as opposed to being country specific?

Will I be flagged for duplicate content by Google?
Hi Moz community, Had a question regarding duplicate content that I can't seem to find the answer to on Google. My agency is working on a large number of franchisee websites (over 40) for one client, a print franchise, that wants a refresh of new copy and SEO. Each print shop has their own 'microsite', though all services and products are the same, the only difference being the location. Each microsite has its own unique domain. To avoid writing the same content over and over in 40+ variations, would all the websites be flagged by Google for duplicate content if we were to use the same base copy, with the only changes being to the store locations (i.e. where we mention Toronto print shop on one site may change to Kelowna print shop on another)? Since the print franchise owns all the domains, I'm wondering if that would be a problem since the sites aren't really competing with one another. Any input would be greatly appreciated. Thanks again!

Duplicate content on URL trailing slash
Hello, Some time ago, we accidentally made changes to our site which modified the way urls in links are generated. At once, trailing slashes were added to many urls (only in links). Links that used to send to
Intermediate & Advanced SEO | | yacpro13
example.com/webpage.html Were now linking to
example.com/webpage.html/ Urls in the xml sitemap remained unchanged (no trailing slash). We started noticing duplicate content (because our site renders the same page with or without the trailing shash). We corrected the problematic php url function so that now, all links on the site link to a url without trailing slash. However, Google had time to index these pages. Is implementing 301 redirects required in this case?1 -
Duplicate content due to parked domains
I have a main ecommerce website with unique content and decent back links. I had few domains parked on the main website as well specific product pages. These domains had some type in traffic. Some where exact product names. So main main website www.maindomain.com had domain1.com , domain2.com parked on it. Also had domian3.com parked on www.maindomain.com/product1. This caused lot of duplicate content issues. 12 months back, all the parked domains were changed to 301 redirects. I also added all the domains to google webmaster tools. Then removed main directory from google index. Now realize few of the additional domains are indexed and causing duplicate content. My question is what other steps can I take to avoid the duplicate content for my my website 1. Provide change of address in Google search console. Is there any downside in providing change of address pointing to a website? Also domains pointing to a specific url , cannot provide change of address 2. Provide a remove page from google index request in Google search console. It is temporary and last 6 months. Even if the pages are removed from Google index, would google still see them duplicates? 3. Ask google to fetch each url under other domains and submit to google index. This would hopefully remove the urls under domain1.com and doamin2.com eventually due to 301 redirects. 4. Add canonical urls for all pages in the main site. so google will eventually remove content from doman1 and domain2.com due to canonical links. This wil take time for google to update their index 5. Point these domains elsewhere to remove duplicate contents eventually. But it will take time for google to update their index with new non duplicate content. Which of these options are best best to my issue and which ones are potentially dangerous? I would rather not to point these domains elsewhere. Any feedback would be greatly appreciated.

No-index pages with duplicate content?
Hello, I have an e-commerce website selling about 20 000 different products. For the most used of those products, I created unique high quality content. The content has been written by a professional player that describes how and why those are useful which is of huge interest to buyers. It would cost too much to write that high quality content for 20 000 different products, but we still have to sell them. Therefore, our idea was to no-index the products that only have the same copy-paste descriptions all other websites have. Do you think it's better to do that or to just let everything indexed normally since we might get search traffic from those pages? Thanks a lot for your help!

Artist Bios on Multiple Pages: Duplicate Content or not?
I am currently working on an eComm site for a company that sells art prints. On each print's page, there is a bio about the artist followed by a couple of paragraphs about the print. My concern is that some artists have hundreds of prints on this site, and the bio is reprinted on every page,which makes sense from a usability standpoint, but I am concerned that it will trigger a duplicate content penalty from Google. Some people are trying to convince me that Google won't penalize for this content, since the intent is not to game the SERPs. However, I'm not confident that this isn't being penalized already, or that it won't be in the near future. Because it is just a section of text that is duplicated, but the rest of the text on each page is original, I can't use the rel=canonical tag. I've thought about putting each artist bio into a graphic, but that is a huge undertaking, and not the most elegant solution. Could I put the bio on a separate page with only the artist's info and then place that data on each print page using an <iframe>and then put a noindex,nofollow in the robots.txt file?</p> <p>Is there a better solution? Is this effort even necessary?</p> <p>Thoughts?</p></iframe>

Duplicate Content on Wordpress b/c of Pagination
On my recent crawl, there were a great many duplicate content penalties. The site is http://dailyfantasybaseball.org. The issue is: There's only one post per page. Therefore, because of wordpress's (or genesis's) pagination, a page gets created for every post, thereby leaving basically every piece of content i write as a duplicate. I feel like the engines should be smart enough to figure out what's going on, but if not, I will get hammered. What should I do moving forward? Thanks!
