301ed Pages Still Showing as Duplicate Content in GWMT
-
I thank anyone reading this for their consideration and time.
We are a large site with millions of URLs for our product pages. We are also a textbook company, so by nature, our products have two separate ISBNs: a 10 digit and a 13 digit form. Thus, every one of our books has at least two pages (10 digit and 13 digit ISBN page). My issue is that we have established a 301 for all the 10 digit URLs so they automatically redirect to the 13 digit page. This fix has been in place for months. However, Google still reports that they are detecting thousands of pages with duplicate title and meta tags. Google is referring to these page URLs that I already have 301ed to the canonical version many months ago! Is there anything that I can do to fix this issue? I don't understand what I am doing wrong.
Example:
http://www.bookbyte.com/product.aspx?isbn=9780321676672
http://www.bookbyte.com/product.aspx?isbn=032167667XAs you can see the 10 digit ISBN page 301s to 13 digit canonical version. Google reports that they have detected duplicate title and meta tags between the two pages and there are thousands of these duplicate pages listed.
To add some further context: The ISBN is just a parameter that allows us to provide content when someone searches for a product with the 10 or 13 digit ISBN. The 13 digit version of the page is the only physical page that exists, the 10 digit is only a part of the virtual URL structure of the website. This is why I cannot simply change the title and meta tags of the 10 digit pages because they only exist in the sense that the URL redirects to the 13 digit version. Also, we submit a sitemap every day of all the 13 digit pages so Google knows exactly what our physical URL structure is. I have submitted this question to GWMT forums and received no replies.

It's solved then, the problem definitely lies within our code. Thanks a lot guys really appreciate your time.

http://www.internetofficer.com/seo-tool/redirect-check/ and http://www.seomastering.com/url-redirect-checker.php both say 'not search friendly'.
Kind of weird, some other tools are showing a 301. Even more weird, when i visit the url, it looks masked and i see http://www.bookbyte.com/productv3.aspx?isbn=9780321676672 (note the "productv3.aspx") which is different from what any of the tools bring back. I'm not a dev so i cant help much more. Something weird going on and i assume that's what google is seeing too.
best of luck!

Thomas,
The reason the process is not working properly is your 10 digit ISBN pages are not being redirected properly. I tried visiting your 10 digit example: http://www.bookbyte.com/product.aspx?isbn=032167667X. I am redirected to the 13 digit page, but the header code returned is 200 which means "all is ok". There should be a 301 code returned. The entire point of the 301 code is to let others (i.e. Google) know the content has moved and they should update their records. Because the 200 code is being returned, no updates are being made.
Bottom line, the redirect was not performed properly. Fix it and your issue will be resolved the next time Google crawls each page. It should take several weeks to completely resolve the issue on your site. I would recommend making the change, confirming it, then waiting 30 days and check WMT.

Ricko,
Thanks a lot for the response greatly appreciated. I just got done looking at the code, again, with the IT guys and they confirmed its a 301 redirect not a 302. Though you are correct the URL tool that you linked to says it is a 302. The mystery deepens. Any other tools that you know of that I can try?

Hi Thomas,
I'm seeing a 302 redirect on http://www.bookbyte.com/product.aspx?isbn=032167667X.
Maybe try this: http://www.webtoolhub.com/tn561352-url-redirection-checker.aspx

Why are my 301 redirects and duplicate pages (with canonicals) still showing up as duplicates in Webmaster Tools?
My guess is that in time Google will realize that my duplicate content is not actually duplicate content, but in the meantime I'd like to get your guys feedback. The reporting in Webmaster Tools looks something like this. Duplicates /url1.html /url2.html /url3.html /category/product/url.html /category2/product/url.html url3.html is the true canonical page in the list above._ url1.html,_ and url2.html are old URLs that 301 to url3.html. So, it seems my bases are covered there. _/category/product/url.html _and _/category2/product/url.html _ do not redirect. They are the same page as url3.html. Each of the category URLs has a canonical URL of url3.html in the header. So, it seems my bases are covered there as well. Can I expect Google to pick up on this? Why wouldn't it understand this already?

Joomla creating duplicate pages, then the duplicate page's canonical points to itself - help!
Using Joomla, every time I create an article a subsequent duplicate page is create, such as: /latest-news/218-image-stabilization-task-used-to-develop-robot-brain-interface and /component/content/article?id=218:image-stabilization-task-used-to-develop-robot-brain-interface The latter being the duplicate. This wouldn't be too much of a problem, but the canonical tag on the duplicate is pointing to itself.. creating mayhem in Moz and Webmaster tools. We have hundreds of duplicates across our website and I'm very concerned with the impact this is having on our SEO! I've tried plugins such as sh404SEF and Styleware extensions, however to no avail. Can anyone help or know of any plugins to fix the canonicals?

Google showing https:// page in search results but directing to http:// page
We're a bit confused as to why Google shows a secure page https:// URL in the results for some of our pages. This includes our homepage. But when you click through it isn't taking you to the https:// page, just the normal unsecured page. This isn't happening for all of our results, most of our deeper content results are not showing as https://. I thought this might have something to do with Google conducting searches behind secure pages now, but this problem doesn't seem to affect other sites and our competitors. Any ideas as to why this is happening and how we get around it?

Duplicate Content Problem!
Hi folks, I have a quite awkward problem. Since a few weeks a get a huge amount of "duplicate content errors" in my MOZ crawl reports. After a while of looking for the error I thought of the domains I've bought additionally. So I went to Google and typed in site:myotherdomains.com The results was as I expected that my original website got indexed with my new domains aswell. That means: For example my original website was index with www.domain.com/aboutus - Then I bought some additional domains which are pointing on my / folder. What happened is that I also get listed with: www.mynewdomains.com/com How can I fix that? I tried a normal domain redirect but it seems as this doesn't help as when I am visiting www.mynewdomains.com the domain doesnt change in my browser to www.myoriginaldomain.com but stays with it ... I was busy the whole day to find a solution but I am kinda desperate now. If somebody could give me advice it would be much appreciated. Mike

Duplicate content
I'm getting an error showing that two separate pages have duplicate content. The pages are: | Help System: Domain Registration Agreement - Registrar Register4Less, Inc. http://register4less.com/faq/cache/11.html 1 27 1 Help System: Domain Registration Agreement - Register4Less Reseller (Tucows) http://register4less.com/faq/cache/7.html | These are both registration agreements, one for us (Register4Less, Inc.) as the registrar, and one for Tucows as the registrar. The pages are largely the same, but are in fact different. Is there a way to flag these pages as not being duplicate content? Thanks, Doug.

Tags causing Duplicate page content?
I was looking through the 'Duplicate Page Content' and Too Many On-Page Link' errors and they all seem to be linked to the 'Tags' on my blog pages. Is this really a problem and if so how should I be using tags properly to get the best SEO rewards?

Duplicate Content
Hi - We are due to launch a .com version of our site, with the ability to put prices into local currency, whereas our .co.uk site will be solely £. If the content on both the .com and .co.uk sites is the same (at product level mainly), will we be penalised? What is the best way to get around this?

Is this considered as duplicate content?
One of my clients has a template page they have used repeatedly each time they have a new news item. The template includes a two-paragraph customer quote/testimonial for the company. So, they now have 100+ pages with the same customer quote. The rest of the page content / body copy is unique. Is there any likelihood of this being considered duplicate content?
