Is this duplicate content something to be concerned about?
-
On the 20th February a site I work on took a nose-dive for the main terms I target. Unfortunately I can't provide the url for this site.
All links have been developed organically so I have ruled this out as something which could've had an impact.
During the past 4 months I've cleaned up all WMT errors and applied appropriate redirects wherever applicable. During this process I noticed that mydomainname.net contained identical content to the main mydomainname.com site. Upon discovering this problem I 301 redirected all .net content to the main .com site. Nothing has changed in terms of rankings since doing this about 3 months ago.
I also found paragraphs of duplicate content on other sites (competitors in different countries). Although entire pages haven't been copied there is still enough content to highlight similarities. As this content was written from scratch and Google would've seen this within it's crawl and index process I wanted to get peoples thoughts as to whether this is something I should be concerned about?
Many thanks in advance.

if you do make sure it is cross-domain rel="canonical"

If you have 301ed it I would not worry about the .net dupes

Did you use the main term in the anchor text a lot ? (exact match or in some combinations ?)
-
Might still be a good idea to add a rel canonical tag to your .com domain.

Duplicate content URLs from bespoke ecommerce CMS - what's the best solution here?
Hi Mozzers Just noticed this pattern on a retail website... This URL product.php?cat=5 is also churning out products.php?cat=5&sub_cat= (same content as product.php?cat=5 but from this different URL - this is a blank subcat - there are also unique subcat pages with unique content - but this one is blank) How should I deal with that? and then I'm seeing: product-detail.php?a_id=NT001RKS0000000 and product-detail.php?a_id=NT001RKS0000000&cont_ref=giftselector (same content as product-detail.php?a_id=NT001RKS0000000 but from this different URL) How should I deal with that? This is a bespoke ecommerce CMS (unfortunately). Any pointers would be great 🙂 Best wishes, Luke

3rd Party hosted whitepapers — bad idea? Duplicate content?
It is common the B2B world to have 3rd parties host your whitepapers for added exposure. Is this a bad practice from an SEO point of view? Is the expectation that the 3rd parties use rel=canonical tags? I doubt most of them do . . .

Why are these pages considered duplicate content?
I have a duplicate content warning in our PRO account (well several really) but I can't figure out WHY these pages are considered duplicate content. They have different H1 headers, different sidebar links, and while a couple are relatively scant as far as content (so I might believe those could be seen as duplicate), the others seem to have a substantial amount of content that is different. It is a little perplexing. Can anyone help me figure this out? Here are some of the pages that are showing as duplicate: http://www.downpour.com/catalogsearch/advanced/byNarrator/narrator/Seth+Green/?bioid=5554 http://www.downpour.com/catalogsearch/advanced/byAuthor/author/Solomon+Northup/?bioid=11758 http://www.downpour.com/catalogsearch/advanced/byNarrator/?mediatype=audio+books&bioid=3665 http://www.downpour.com/catalogsearch/advanced/byAuthor/author/Marcus+Rediker/?bioid=10145 http://www.downpour.com/catalogsearch/advanced/byNarrator/narrator/Robin+Miles/?bioid=2075

Moving some content to a new domain - best practices to avoid duplicate content?
Hi We are setting up a new domain to focus on a specific product and want to use some of the content from the original domain on the new site and remove it from the original. The content is appropriate for the new domain and will be irrelevant for the original domain and we want to avoid creating completely new content. There will be a link between the two domains. What is the best practice for this to avoid duplicate content and a potential Panda penalty?

Magento Duplicate Content Recovery
Hi, we switched platforms to Magento last year. Since then our SERPS rankings have declined considerably (no sudden drop on any Panda/Penguin date lines). After investigating, it appeared we neglected to No index, follow all our filter pages and our total indexed pages rose sevenfold in a matter of weeks. We have since fixed the no index issue and the pages indexed are now below what we had pre switch to Magento. We've seen some positive results in the last week. Any ideas when/if our rankings will return? Thanks!

Duplicate Content On A Subdomain
Hi, We have a client who is currently close to completing a site specifically aimed at the UK market (they're doing this in-house so we've had no say in how it will work). The site will almost be a duplicate (in terms of content, targeted keywords etc.) of a section of the main site (that sits on the root domain) - the main site is targeted toward the US. The only difference will be certain spellings and currency type. If this new UK site were to sit on a sub domain of the main site, which is a .com, will this cause duplicate content issues? I know that there wouldn't be an issue if the new site were to be on a separate .co.uk domain (according to Matt Cutts), but it looks like the client wants it to be on a sub domain. Any help/advice would be greatly appreciated.
