Duplicate Content | eBay
-
My client is generating templates for his eBay template based on content he has on his eCommerce platform.
I'm 100% sure this will cause duplicate content issues. My question is this.. and I'm not sure where eBay policy stands with this but adding the canonical tag to the template.. will this work if it's coming from a different page i.e. eBay?
Update:
I'm not finding any information regarding this on the eBay policy's: http://ocs.ebay.com/ws/eBayISAPI.dll?CustomerSupport&action=0&searchstring=canonical
So it does look like I can have rel="canonical" tag in custom eBay templates but I'm concern this can be considered: "cheating" since rel="canonical is actually a 301 but as this says: http://googlewebmastercentral.blogspot.com/2009/12/handling-legitimate-cross-domain.html it's legitimately duplicate content.
The question is now: should I add it or not?
UPDATE seems eBay templates are embedded in a iframe but the snap shot on google actually shows the template. This makes me wonder how they are handling iframes now. looking at http://www.webmaster-toolkit.com/search-engine-simulator.shtml does shows the content inside the iframe. Interesting.
Anyone else have feedback?

Well,
I have client account examined here on MOZ. He's got huge duplicated content and it definitely sounds to me like it is duplicating the content from the site to Ebay.
I'll post back about that, but definitly something to consider. I guess if Google has to choose beetween a site and Ebay... it is going to be tough to fight for SERPS against Ebay.

eBay does not care about duplicate content unless copyright involves. Great image and great price is the ebay to sell on ebay.

Agree with Stephan here - eBay's extremely unlikely to give you control over the rel=canonical on their product pages, but generally, the content duplication by having the product info on their site shouldn't harm you.
If you're really worried, provide more detail/depth/content on your own site than what you do on eBay, and possibly consider having different title/product name conventions. There's lots of good ways to describe the same product.

You can have canonical from one domain to another.
I am talking about have the ability to actually control eBay's meta data at the canonical level. They already have canonical tags going back to their own pages and I doubt they would give you control over it. Again, I am not 100% sure but I would be shocked if they gave you control of that field. eBay has its own SEO concerns so I image they would retain control of that field.
I just don't consider a product page on eBay to be a duplicate of a product page on a third party site even if the site were feeding the data to eBay. Your site and eBay are 2 totally separate entities and I don't think these would be considered duplicate pages.

yea me too: Listening to Matt Cutts here: http://www.mattcutts.com/blog/rel-canonical-html-head/ If you want to fast forward to: 1:30 and it seems to me that hes saying that you can have a canonical from what I understand: anywhere. Hearing that and wondering how the search engines REALLY interpret iframes ( as they want to read a site more like a human ) how will they handle the canonical.
Sure not 100% of the site actually us a duplicate but the main stuff is. It makes me wonder. I'll really know if I see a backlink from eBay in OSE.
( not saying that that is the goal but the content is ours and if the shoe was on the other foot and we getting penalized..) -
I am not sure you can control the canonical tag of an eBay page. I think eBay will have the main control... you can maybe add it to the iFrame but I think eBay's headers will be the ones that have dominance.
I also don't think having eBay product pages would be considered duplicate content. We have numerous product feeds going to third party shopping sites and I don't consider this to be duplicate content at all.
However, I am only slightly familiar with eBay. It will be interesting to see other answers on the subject.

Removing duplicate content
Due to URL changes and parameters on our ecommerce sites, we have a massive amount of duplicate pages indexed by google, sometimes up to 5 duplicate pages with different URLs. 1. We've instituted canonical tags site wide. 2. We are using the parameters function in Webmaster Tools. 3. We are using 301 redirects on all of the obsolete URLs 4. I have had many of the pages fetched so that Google can see and index the 301s and canonicals. 5. I created HTML sitemaps with the duplicate URLs, and had Google fetch and index the sitemap so that the dupes would get crawled and deindexed. None of these seems to be terribly effective. Google is indexing pages with parameters in spite of the parameter (clicksource) being called out in GWT. Pages with obsolete URLs are indexed in spite of them having 301 redirects. Google also appears to be ignoring many of our canonical tags as well, despite the pages being identical. Any ideas on how to clean up the mess?

Case Sensitive URLs, Duplicate Content & Link Rel Canonical
I have a site where URLs are case sensitive. In some cases the lowercase URL is being indexed and in others the mixed case URL is being indexed. This is leading to duplicate content issues on the site. The site is using link rel canonical to specify a preferred URL in some cases however there is no consistency whether the URLs are lowercase or mixed case. On some pages the link rel canonical tag points to the lowercase URL, on others it points to the mixed case URL. Ideally I'd like to update all link rel canonical tags and internal links throughout the site to use the lowercase URL however I'm apprehensive! My question is as follows: If I where to specify the lowercase URL across the site in addition to updating internal links to use lowercase URLs, could this have a negative impact where the mixed case URL is the one currently indexed? Hope this makes sense! Dave

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?

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 -
PDF for link building - avoiding duplicate content
Hello, We've got an article that we're turning into a PDF. Both the article and the PDF will be on our site. This PDF is a good, thorough piece of content on how to choose a product. We're going to strip out all of the links to our in the article and create this PDF so that it will be good for people to reference and even print. Then we're going to do link building through outreach since people will find the article and PDF useful. My question is, how do I use rel="canonical" to make sure that the article and PDF aren't duplicate content? Thanks.

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,
