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?

Same product in different categories and duplicate content issues
Hi,I have some questions related to duplicate content on e-commerce websites. 1)If a single product goes to multiple categories (eg. A black elegant dress could be listed in two categories like "black dresses" and "elegant dresses") is it considered duplicate content even if the product url is unique? e.g www.website.com/black-dresses/black-elegant-dress duplicated> same content from two different paths www.website.com/elegant-dresses/black-elegant-dress duplicated> same content from two different paths www.website.com/black-elegant-dress unique url > this is the way my products urls look like Does google perceive this as duplicated content? The path to the content is only one, so it shouldn't be seen as duplicated content, though the product is repeated in different categories.This is the most important concern I actually have. It is a small thing but if I set this wrong all website would be affected and thus penalised, so I need to know how I can handle it. 2- I am using wordpress + woocommerce. The website is built with categories and subcategories. When I create a product in the product page backend is it advisable to select just the lowest subcategory or is it better to select both main category and subcategory in which the product belongs? I usually select the subcategory alone. Looking forward to your reply and suggestions. thanks

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 through 'Gclid'
Hello, We've had the known problem of duplicate content through the gclid parameter caused by Google Adwords. As per Google's recommendation - we added the canonical tag to every page on our site so when the bot came to each page they would go 'Ah-ha, this is the original page'. We also added the paramter to the URL parameters in Google Wemaster Tools. However, now it seems as though a canonical is automatically been given to these newly created gclid pages; below https://www.google.com.au/search?espv=2&q=site%3Awww.mypetwarehouse.com.au+inurl%3Agclid&oq=site%3A&gs_l=serp.3.0.35i39l2j0i67l4j0i10j0i67j0j0i131.58677.61871.0.63823.11.8.3.0.0.0.208.930.0j3j2.5.0....0...1c.1.64.serp..8.3.419.nUJod6dYZmI Therefore these new pages are now being indexed, causing duplicate content. Does anyone have any idea about what to do in this situation? Thanks, Stephen.

Duplicate Content www vs. non-www and best practices
I have a customer who had prior help on his website and I noticed a 301 redirect in his .htaccess Rule for duplicate content removal : www.domain.com vs domain.com RewriteCond %{HTTP_HOST} ^MY-CUSTOMER-SITE.com [NC]
Intermediate & Advanced SEO | | EnvoyWeb
RewriteRule (.*) http://www.MY-CUSTOMER-SITE.com/$1 [R=301,L,NC] The result of this rule is that i type MY-CUSTOMER-SITE.com in the browser and it redirects to www.MY-CUSTOMER-SITE.com I wonder if this is causing issues in SERPS. If I have some inbound links pointing to www.MY-CUSTOMER-SITE.com and some pointing to MY-CUSTOMER-SITE.com, I would think that this rewrite isn't necessary as it would seem that Googlebot is smart enough to know that these aren't two sites. -----Can you comment on whether this is a best practice for all domains?
-----I've run a report for backlinks. If my thought is true that there are some pointing to www.www.MY-CUSTOMER-SITE.com and some to the www.MY-CUSTOMER-SITE.com, is there any value in addressing this?0 -
Problems with ecommerce filters causing duplicate content.
We have an ecommerce website with 700 pages. Due to the implementation of filters, we are seeing upto 11,000 pages being indexed where the filter tag is apphended to the URL. This is causing duplicate content issues across the site. We tried adding "nofollow" to all the filters, we have also tried adding canonical tags, which it seems are being ignored. So how can we fix this? We are now toying with 2 other ideas to fix this issue; adding "no index" to all filtered pages making the filters uncrawble using javascript Has anyone else encountered this issue? If so what did you do to combat this and was it successful?

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 internal links on page, any benefit to nofollow
Link spam is naturally a hot topic amongst SEO's, particularly post Penguin. While digging around forums etc, I watched a video blog from Matt Cutts posted a while ago that suggests that Google only pays attention to the first instance of a link on the page As most websites will have multiple instances of a links (header, footer and body text), is it beneficial to nofollow the additional instances of the link? Also as the first instance of a link will in most cases be within the header nav, does that then make the content link text critical or can good on page optimisation be pulled from the title attribute? I would appreciate the experiences and thoughts Mozzers thoughts on this thanks in advance!

Duplicate Content on Press Release?
Hi, We recently held a charity night in store. And had a few local celebs turn up etc... We created a press release to send out to various media outlets, within the press release were hyperlinks to our site and links on certain keywords to specific brands on our site. My question is, should we be sending a different press release to each outlet to stop the duplicate content thing, or is sending the same release out to everyone ok? We will be sending approx 20 of these out, some going online and some not. So far had one local paper website, a massive football website and a local magazine site. All pretty much same content and a few pics. Any help, hints or tips on how to go about this if I am going to be sending out to a load of other sites/blogs? Cheers
