Duplicate content issue
-
Hi
I installed a wiki and a forum to subdomains of one of my sites. The crawl report shows me duplicate content on the forum and on wiki. This will hurt the main site? Or the root domain? the site by the way is clean absolutely from errors. Thanks

Hi Dr Peter,
I just wanted to add some extra info for the readers. This was my goal. Its ok Wiki is gone for moment, as for the forum most possible I will make it as you advice (no index). as I dont seek traffic from it.I dont have time to manage everything. Thanks for your time

Sorry, I'm slightly confused. Are the wiki and forum duplicating each other, or are they each duplicating content on your root domain. Even in a sub-domain, they could be diluting content in your root domain, but it really depends a lot on the situation and extent of the duplication.
You could use the canonical tag to point them to the source of the content, or you could block them (probably META NOINDEX), but I'd like to understand the goals a bit better.

Actually, the original poster mentioned a wiki, but said nothing about wikipedia. I'm going to ask another associate to also look at this thread and chime in to make sure we've got this figured out correctly.

Thanks!

Hey Nikos, if you are using wiki and forum in subdomains then surely you should getting duplicate content issue in webmaster because wiki takes first few content of a Wikipedia article and pastes it into your blog post. A link to the corresponding article is also included.
But I think as long as you have more unique content to over power that of a few content of wikipedia article and putting it at the end of the blog, it not being a problem as many sites use snippets of content from others as references.
I suggest you to please ensure that the main page shouldn't link to the subdomains in that case but subdomain can link to main domain. I think in that way your main domain will not get affected.
Well I advice you to read "How Changes To The Way Google Handles Subdomains Impact SEO" post, I am sure you will find solution. Thanks Cheers!

Cool! Is any way to eliminate them? Or is not necessary? I read one article about duplicate content article about forums and was written that google dont punish forums if they have duplicate content (inside the site) like pages,titles and stuff. Is true or that change? me personal I dont care to much about subdomains because I am promoting the main site and forum + wiki are just bonus for my visitors! ohh , by the way harald another tactic what i practise and is working is the folloing. i SCAN ALL the top 20 results and I am building the same backlinks. I mean from the same page. this what I can ofcource. but if you analyze them all you collect few good. rest I am buying them to pass my competitors. I am not an expert or whatever , so any advice will be appreciated. thanks

Hi Nikos, if this are sub domains it will not hurt your main side -
sub domains a treated separately.Harry

I think the best solution is to use rel cannonical in the head section. Do you tried it?
You will need to include in every page (pages you want to be the official one) inside the head tag the follow:
where ww.example.com/index.html is your page adress. Good luck!

Duplicate content across different domains in different countries?
Hi Guys, We have a 4 sites One in NZ, UK, Canada and Australia. All geo-targeting their respective countries in Google Search Console. The sites are identical. We recently added the same content to all 4 sites. Will this cause duplicate content issues or any issues even though they are in different countries and geo-targeting is set? Cheers.

Duplicate Content: Is a product feed/page rolled out across subdomains deemed duplicate content?
A company has a TLD (top-level-domain) which every single product: company.com/product/name.html The company also has subdomains (tailored to a range of products) which lists a choosen selection of the products from the TLD - sort of like a feed: subdomain.company.com/product/name.html The content on the TLD & subdomain product page are exactly the same and cannot be changed - CSS and HTML is slightly differant but the content (text and images) is exactly the same! My concern (and rightly so) is that Google will deem this to be duplicate content, therfore I'm going to have to add a rel cannonical tag into the header of all subdomain pages, pointing to the original product page on the TLD. Does this sound like the correct thing to do? Or is there a better solution? Moving on, not only are products fed onto subdomain, there are a handfull of other domains which list the products - again, the content (text and images) is exactly the same: other.com/product/name.html Would I be best placed to add a rel cannonical tag into the header of the product pages on other domains, pointing to the original product page on the actual TLD? Does rel cannonical work across domains? Would the product pages with a rel cannonical tag in the header still rank? Let me know if there is a better solution all-round!

Duplicate Page Content - Shopify
Moz reports that there are 1,600+ pages on my site (Sportiqe.com) that qualify as Duplicate Page Content. The website sells licensed apparel, causing shirts to go into multiple categories (ie - LA Lakers shirts would be categorized in three areas: Men's Shirts, LA Lakers Shirts and NBA Shirts)It looks like "tags" are the primary cause behind the duplicate content issues: // Collection Tags_Example: : http://www.sportiqe.com/collections/la-clippers-shirts (Preferred URL): http://www.sportiqe.com/collections/la-clippers-shirts/la-clippers (URL w/ tag): http://sportiqe.com/collections/la-clippers-shirts/la-clippers (URL w/ tag, w/o the www.): http://sportiqe.com/collections/all-products/clippers (Different collection, w/ tag and same content)// Blog Tags_Example: : http://www.sportiqe.com/blogs/sportiqe/7902801-dispatch-is-back: http://www.sportiqe.com/blogs/sportiqe/tagged/elias-fundWould it make sense to do 301 redirects for the collection tags and use the Parameter Tool in Webmaster Tools to exclude blog post tags from their crawl? Or, is there a possible solution with the rel=cannonical tag?Appreciate any insight from fellow Shopify users and the Moz community.

How do I geo-target continents & avoid duplicate content?
Hi everyone, We have a website which will have content tailored for a few locations: USA: www.site.com
Intermediate & Advanced SEO | | AxialDev
Europe EN: www.site.com/eu
Canada FR: www.site.com/fr-ca Link hreflang and the GWT option are designed for countries. I expect a fair amount of duplicate content; the only differences will be in product selection and prices. What are my options to tell Google that it should serve www.site.com/eu in Europe instead of www.site.com? We are not targeting a particular country on that continent. Thanks!0 -
Duplicate Content Question
My understanding of duplicate content is that if two pages are identical, Google selects one for it's results... I have a client that is literally sharing content real-time with a partner...the page content is identical for both sites, and if you update one page, teh otehr is updated automatically. Obviously this is a clear cut case for canonical link tags, but I'm cuious about something: Both sites seem to show up in search results but for different keywords...I would think one domain would simply win out over the other, but Google seems to show both sites in results. Any idea why? Also, could this duplicate content issue be hurting visibility for both sites? In other words, can I expect a boost in rankings with the canonical tags in place? Or will rankings remain the same?

Concerns about duplicate content issues with australian and us version of website
My company has an ecommerce website that's been online for about 5 years. The url is www.betterbraces.com. We're getting ready to launch an australian version of the website and the url will be www.betterbraces.com.au. The australian website will have the same look as the US website and will contain about 200 of the same products that are featured on the US website. The only major difference between the two websites is the price that is charged for the products. The australian website will be hosted on the same server as the US website. To ensure Australians don't purchase from the US site we are going to have a geo redirect in place that sends anyone with a AU ip address to the australian website. I am concerned that the australian website is going to have duplicate content issues. However, I'm not sure if the fact that the domains are so similar coupled with the redirect will help the search engines understand that these sites are related. I would appreciate any recommendations on how to handle this situation to ensure oue rankings in the search engines aren't penalized. Thanks in advance for your help. Alison French

How to deal with category browsing and duplicate content
On an ecommerce site there are typically a lot of pages that may appear to be duplications due to category browse results where the only difference may be the sorting by price or number of products per page. How best to deal with this? Add nofollow to the sorting links? Set canonical values that ignore these variables? Set cononical values that match the category home page? Is this even a possible problem with Panda or spiders in general?
