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

Car Dealership website - Duplicate Page Content Issues
Hi, I am currently working on a large car dealership website. I have just had a Moz crawl through and its flagging a lot of duplicate page content issues, these are mostly for used car pages. How can I get round this as the site stocks many of the same car, model, colour, age, millage etc. Only unique thing about them is the reg plate. How do I get past this duplicate issue if all the info is relatively the same? Anyone experienced this issue when working on a car dealership website? Thank you.

http://www.website.co.uk/news/archive/2015/01 (Jan) I am wondering if there's a duplicate issue here or not given that I also articles by month as well and if so how best I handle this.? I already do pagination on my news pages (page 1 , page 2) by using rel=next and rel=Prev but I don't have an canconical or anything as yet. I enclose a couple of links if this would help and would appreciate if someone could take a browse. I have a View All link on my homepage for for all news items - http://goo.gl/JPPIvQ I which have a different urls - March 2015 Articles - http://goo.gl/0O1wYD and April 2015 articles - http://goo.gl/GdW2oK On another note, These articles are also linked to from the relevant category landing pages on my website to help with SEO. I have not used H tags on the article links in my landing pages , just displaying the weblink back to the news article.I've done this to try and improve the PR and rankings of my landing pages. Just wondered if anyone has any comments as to whether thats a good or bad idea and whether I could improve it in any way - An example is here (scroll down the page to the pressure washing guides) - http://goo.gl/nnRE49 Thanks Pete0 -
Duplicate page content & titles on the same domain
Hey, My website: http://www.electromarket.co.uk is running Magento Enterprise. The issue I'm running into is that the URLs can be shortened and modified to display different things on the website itself. Here's a few examples. Product Page URL: http://www.electromarket.co.uk/speakers-audio-equipment/dj-pa-speakers/studio-bedroom-monitors/bba0051 OR I could remove everything in the URL and just have: http://www.electromarket.co.uk/bba0051 and the link will work just as well. Now my problem is, these two URL's load the same page title, same content, same everything, because essentially they are the very same web page. But how do I tell Google that? Do I need to tell Google that? And would I benefit by using a redirect for the shorter URLs? Thanks!

I'm not sure where the second version of the URL is coming from. Thanks,

Duplicate content problem?
Hello! I am not sure if this is a problem or if I am just making something too complicated. Here's the deal. I took on a client who has an existing site in something called homestead. Files cannot be downloaded, making it tricky to get out of homestead. The way it is set up is new sites are developed on subdomains of homestead.com, and then your chosen domain points to this subdomain. The designer who built it has kindly given me access to her account so that I can edit the site, but this is awkward. I want to move the site to its own account. However, to do so Homestead requires that I create a new subdomain and copy the files from one to the other. They don't have any way to redirect the prior subdomain to the new one. They recommend I do something in the html, since that is all I can access. Am I unnecessarily worried about the duplicate content consequences? My understanding is that now I will have two subdomains with the same exact content. True, over time I will be editing the new one. But you get what I'm sayin'. Thanks!

Duplicate content in Magento
Hi all We got some serious issues with duplicate content on a Magento site that we are marketing. For example: http://www.citcop.se/varmepumpar-luft-luft/panasonic/panasonic-nordic-ce9nke-5-0kw http://www.citcop.se/panasonic/panasonic-nordic-ce9nke-5-0kw http://www.citcop.se/panasonic-nordic-ce9nke-5-0kw All of the above seem to work just fine as it is now but since they are excatly the same product they should ofcourse do a 301 redirect to the main page. Any ideas on how to sort this out in Magnto without having to resort to manual work in .htaccess? Have a great day Fredrik

Duplicate content
Greetings! I have inherited a problem that I am not sure how to fix. The website I am working on had a 302 redirect from its original home url (with all the link juice) to a newly designed page (with no real link juice). When the 302 redirect was removed, a duplicate content problem remained, since the new page had already been indexed by google. What is the best way to handle duplicate content? Thanks!
