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!

How to avoid duplicate content
Hi there, Our client has an ecommerce website, their products are also showing on an aggregator website (aka on a comparison website where multiple vendors are showing their products). On the aggregator website the same photos, titles and product descriptions are showing. Now with building their new website, how can we avoid such duplicate content? Or does Google even care in this case? I have read that we could show more product information on their ecommerce website and less details on the aggregator's website. But is there another or better solution? Many thanks in advance for any input!

Concerns of Duplicative Content on Purchased Site
Recently I purchased a site of 50+ DA (oldsite.com) that had been offline/404 for 9-12 months from the previous owner. The purchase included the domain and the content previously hosted on the domain. The backlink profile is 100% contextual and pristine. Upon purchasing the domain, I did the following: Rehosted the old site and content that had been down for 9-12 months on oldsite.com Allowed a week or two for indexation on oldsite.com Hosted the old content on my newsite.com and then performed 100+ contextual 301 redirects from the oldsite.com to newsite.com using direct and wild card htaccess rules Issued a Press Release declaring the acquisition of oldsite.com for newsite.com Performed a site "Change of Name" in Google from oldsite.com to newsite.com Performed a site "Site Move" in Bing/Yahoo from oldsite.com to newsite.com It's been close to a month and while organic traffic is growing gradually, it's not what I would expect from a domain with 700+ referring contextual domains. My current concern is around original attribution of content on oldsite.com shifting to scraper sites during the year or so that it was offline. For Example: Oldsite.com has full attribution prior to going offline Scraper sites scan site and repost content elsewhere (effort unsuccessful at time because google know original attribution) Oldsite.com goes offline Scraper sites continue hosting content Google loses consumer facing cache from oldsite.com (and potentially loses original attribution of content) Google reassigns original attribution to a scraper site Oldsite.com is hosted again and Google no longer remembers it's original attribution and thinks content is stolen Google then silently punished Oldsite.com and Newsite.com (which it is redirected to) QUESTIONS Does this sequence have any merit? Does Google keep track of original attribution after the content ceases to exist in Google's search cache? Are there any tools or ways to tell if you're being punished for content being posted else on the web even if you originally had attribution? Unrelated: Are there any other steps that are recommend for a Change of site as described above.

Tools to scan entire site for duplicate content?
HI guys, Just wondering if anyone knows of any tools to scan a site for duplicate content (with other sites on the web). Looking to quickly identify product pages containing duplicate content/duplicate product descriptions for E-commerce based websites. I know copy scape can which can check up to 10,000 pages in a single operation with Batch Search. But just wondering if there is anything else on the market i should consider looking at? Cheers, Chris

Magento products and eBay - duplicate content risk?
Hi, We are selling about 1000 sticker products in our online store and would like to expand a large part of our products lineup to eBay as well. There are pretty good modules for this as I've heard. I'm just wondering if there will be duplicate content problems if I sync the products between Magento and eBay and they get uploaded to eBay with identical titles, descriptions and images? What's the workaround in this case? Thanks!

Duplicate content - Images & Attachments
I have been looking a GWT HTML improvements on our new site and I am scratching my head on how to stop some elements of the website showing up as duplicates for Meta Descriptions and Titles. For example the blog area: <a id="zip_0-anchor" class="zippedsection_title"></a>This blog is full of information and resources for you to implement; get more traffic, more leads an /blog//blog/page/2//blog/page/3//blog/page/4//blog/page/6//blog/page/9/The page has rel canonicals on them (using Yoast Wordpress SEO) and I can't see away of stopping the duplicate content. Can anyone suggest how to combat this? or is there nothing to worry about?

Multi-language, multi-country localized website with duplicate content penalty
My company website is multi-language and multi-country. Content created for the Global (English-language only, root directory) site is automatically used when no localization exists for the language and country choice (i.e. Brazil). I'm concerned this may be harming our SEO through dupe content penalties. Can anyone confirm this is possible? Any recommendations on how to solve the issue? Maybe the canonical tag? Thanks very much!

Removing Duplicate Page Content
Since joining SEOMOZ four weeks ago I've been busy tweaking our site, a magento eCommerce store, and have successfully removed a significant portion of the errors. Now I need to remove/hide duplicate pages from the search engines and I'm wondering what is the best way to attack this? Can I solve this in one central location, or do I need to do something in the Google & Bing webmaster tools? Here is a list of duplicate content http://www.unitedbmwonline.com/?dir=asc&mode=grid&order=name http://www.unitedbmwonline.com/?dir=asc&mode=list&order=name

Subdomains - duplicate content - robots.txt
Our corporate site provides MLS data to users, with the end goal of generating leads. Each registered lead is assigned to an agent, essentially in a round robin fashion. However we also give each agent a domain of their choosing that points to our corporate website. The domain can be whatever they want, but upon loading it is immediately directed to a subdomain. For example, www.agentsmith.com would be redirected to agentsmith.corporatedomain.com. Finally, any leads generated from agentsmith.easystreetrealty-indy.com are always assigned to Agent Smith instead of the agent pool (by parsing the current host name). In order to avoid being penalized for duplicate content, any page that is viewed on one of the agent subdomains always has a canonical link pointing to the corporate host name (www.corporatedomain.com). The only content difference between our corporate site and an agent subdomain is the phone number and contact email address where applicable. Two questions: Can/should we use robots.txt or robot meta tags to tell crawlers to ignore these subdomains, but obviously not the corporate domain? If question 1 is yes, would it be better for SEO to do that, or leave it how it is?
