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.

Oh, wow - if you're talking a couple of years ago and major ranking drops, then definitely get aggressive. Remove as many as possible and Robots No-index them. If you've got the Robots.txt directives in place, Google shouldn't put them back (although, from past experience, I realize "shouldn't" isn't a guarantee). If you're down 90%, you've got very little to lose and clearly Google didn't like something about that set-up.
Unfortunately, that's about the most drastic, reasonable option. The next step would be to start over with a fresh domain and kill all of the old domains. That could be a lot more hazardous, though.

Thank you Dr. Peter.
Couple of years ago my search engine positions tanked by around 90% and have not picked up back yet. At that time assumed it was due to the duplicate content on these domains, as they were parked ( Not 301, just domain masking) at that point. To avoid that duplicate content problem I moved to 301 redirection. None of these domains have any link juice to speak. Some domains have some typein traffic. I was just trying to capture them rather than link jiuice.
I did de-index most of the domains from webmaster tools in the past. But Google put them back, after 90 days or so. 301 redirection in place did not help that much.
If Google thinks there is a chance of abuse of the 301 of new domains, I would start removing the new domains completely and point else where so that Google can have some new content.

Ugh... 75 is a chunk. The problem is that Google isn't a huge fan of 301-redirecting a bunch of new domains, because it's been too often abused in the past by people buying up domains with history and trying to consolidate PageRank. So, it's possible that (1) they're suspicious of these domains, or (2) they're just not crawling/caching them in a timely manner, since they used to be parked.
Personally, unless there's any link value at all to these, I'd consider completely de-indexing the duplicate domains - at this point that probably does mean removal in Google Search Console and adding Robots.txt (which might be a prerequisite of removal, but I can't recall).
Otherwise, your only real option is just to give the 301-redirects time. It may be a non-issue, and Google is just taking its time. Ultimately, the question is whether these are somehow harming the parent site. If Google is just indexing a few pages but you're not being harmed, I might leave it alone and let the 301s do their work over time. I checked some headers, and they seem to be set up properly.
If you're seeing harm or the wrong domains being returned in search, and if no one is linking to those other domains, then I'd probably be more aggressive and go for all-out removal.

Hello Dr.Peter
Thank you for helping out.
There are around 75 or so domains pointing to the main website. When they were parked (prior to November 2014) on the main site, they were added as additional domains, which were url masked. So at least 30 domains were indexed in google with same content as main content.
12 months back, I realized the duplicate content error and changed the domain parking to 301 redirects. Also used ‘remove url’ functionality in Google Webmaster tools. Even after 12 months, I noticed a number of domains had duplicate contents in google index.
This I removed the pages from the addon domains again using google webmaster tools.To give you an idea my main site with original content/links is iscripts.com and an addon domain socialappster.com is pointed to a product page at iscripts.com/socialware. If you do a site: socialappster.com in google you find few pages in google index, even though it is 301 redirect for more than 12 months now. Similar issue with other domains pointing to product pages as well as whole site.
Appreciate any direction you can provide to clean this mess.
Thanks

Oh, and how many domains are we talking (ballpark)?
-
What was happening when they were parked - were they 302-redirected or was it some kind of straight CNAME situation where, theoretically, Google shouldn't have even seen the parked domains? Trick, of course, is that Google is a registrar, so they can see a lot that isn't necessarily public or crawlable.
Did the additional domains get indexed while parked, or after you went to 301-redirects?

Migrating Subfolder content to New domain Safely
Hello everyone, I'm currently facing a challenging situation and would greatly appreciate your expertise and guidance. I own a website, maniflexa.com, primarily focused on the digital agency niche. About 3 months ago, I created a subfolder, maniflexa.com/emploi/, dedicated to job listings which is a completely different niche. The subfolder has around 120 posts and pages. Unfortunately, since I created the subfolder, the rankings of my main site have been negatively impacted. I was previously ranking #1 for all local digital services keywords, but now, only 2 out of 16 keywords have maintained their positions. Other pages have dropped to positions 30 and beyond. I'm considering a solution and would like your advice: I'm planning to purchase a new domain and migrate the content from maniflexa.com/emploi/ to newdomain.com. However, I want to ensure a smooth migration without affecting the main domain maniflexa.com rankings and losing backlinks from maniflexa.com/emploi/ pages. Is moving the subfolder content to a new domain a viable solution? And how can I effectively redirect all pages from the subfolder to the new domain while preserving page ranks and backlinks?

I wish they did, but GSC doesn't offer a solution to migration content from subfolder to a new domain. 😢 Help a fellow Mozer. Thanks for giving a hand.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?

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! Kian

News sites & Duplicate content
Hi SEOMoz I would like to know, in your opinion and according to 'industry' best practice, how do you get around duplicate content on a news site if all news sites buy their "news" from a central place in the world? Let me give you some more insight to what I am talking about. My client has a website that is purely focuses on news. Local news in one of the African Countries to be specific. Now, what we noticed the past few months is that the site is not ranking to it's full potential. We investigated, checked our keyword research, our site structure, interlinking, site speed, code to html ratio you name it we checked it. What we did pic up when looking at duplicate content is that the site is flagged by Google as duplicated, BUT so is most of the news sites because they all get their content from the same place. News get sold by big companies in the US (no I'm not from the US so cant say specifically where it is from) and they usually have disclaimers with these content pieces that you can't change the headline and story significantly, so we do have quite a few journalists that rewrites the news stories, they try and keep it as close to the original as possible but they still change it to fit our targeted audience - where my second point comes in. Even though the content has been duplicated, our site is more relevant to what our users are searching for than the bigger news related websites in the world because we do hyper local everything. news, jobs, property etc. All we need to do is get off this duplicate content issue, in general we rewrite the content completely to be unique if a site has duplication problems, but on a media site, im a little bit lost. Because I haven't had something like this before. Would like to hear some thoughts on this. Thanks,

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

Duplicate content on ecommerce sites
I just want to confirm something about duplicate content. On an eCommerce site, if the meta-titles, meta-descriptions and product descriptions are all unique, yet a big chunk at the bottom (featuring "why buy with us" etc) is copied across all product pages, would each page be penalised, or not indexed, for duplicate content? Does the whole page need to be a duplicate to be worried about this, or would this large chunk of text, bigger than the product description, have an effect on the page. If this would be a problem, what are some ways around it? Because the content is quite powerful, and is relavent to all products... Cheers,
