Quick Fix to "Duplicate page without canonical tag"?
-
When we pull up Google Search Console, in the Index Coverage section, under the category of Excluded, there is a sub-category called ‘Duplicate page without canonical tag’. The majority of the 665 pages in that section are from a test environment.
If we were to include in the robots.txt file, a wildcard to cover every URL that started with the particular root URL ("www.domain.com/host/"), could we eliminate the majority of these errors?
That solution is not one of the 5 or 6 recommended solutions that the Google Search Console Help section text suggests. It seems like a simple effective solution. Are we missing something?

No index & test Indexing Before You Launch
The domains are intended for development use and cannot be used for production. A custom or CMS-standard will only work
robots.txt on
Live environments with a custom domain. Adding sub-domains (i.e.,dev.example.com , ``test.example.com
) for DEV or TEST will remove the header only,X-Robots-Tag: noindex
but still, serve the domain.robots.txt
To support pre-launch SEO testing, we allow the following bots access to platform domains:
- Site Auditor by Raven
- SEMrush
- RogerBot by Moz
- Dotbot by Moz
If you’re testing links or SEO with other tools, you may request the addition of the tool to our
robots.txt
Pantheon's documentation on robots.txt: http://pantheon.io/docs/articles/sites/code/bots-and-indexing/User-agent: * Disallow: / User-agent: RavenCrawler User-agent: rogerbot User-agent: dotbot User-agent: SemrushBot User-agent: SemrushBot-SA Allow: /

The simplest solution would be to mark every page in your test environment "noindex". This is normally standard operating procedure anyway because most people don't want customers stumbling across the wrong URL in search by mistake and seeing a buggy page that isn't supposed to be "live" for customers.
Updating your robots.txt file would tell Google not to crawl the page, but if they've already crawled it and added it to their index it just means that they will retain the last crawled version of the page and will not crawl it in the future. You have to direct Google to "noindex" the pages. It will take some time as Google refreshes the crawl of each page, but eventually you'll see those errors drop off as Google removes those pages from their index. If I were consulting a client I would tell them to make the change and check back in two or three months.
Hope this helps!

The new version of search console will show all the pages available on your site. even the no-index pages, why? I don't know, the truth is even when you set up those pages as no-follow and no-index it will keeping show you the same error. That does not mean that there is something wrong with your site. I would not worry in your case.

How do I prevent duplicate page title errors from being generated by my multiple shop pages?
Our e-commerce shop has numerous pages within the main shop page. Users navigate through the shop via typical pagination. So while there may be 6 pages of products it's all still under the main shop page. Moz keeps flagging my shop pages as having duplicate titles (ie shop page 2). But they're all the same page. Users aren't loading unique pages each time they go to the next page of products and they aren't pages I can edit. I'm not sure how to prevent this issue from popping up on my reports.

My sites "pages indexed by Google" have gone up more than qten-fold.
Prior to doing a little work cleaning up broken links and keyword stuffing Google only indexed 23/333 pages. I realize it may not be because of the work but now we have around 300/333. My question is is this a big deal? cheers,

Content Duplication and Canonical Tag settings
Hi all, I have a question regarding content duplication.My site has posted one fresh content in the article section and set canonical in the same page for avoiding content duplication._But another webmaster has taken my post and posted the same in his site with canonical as his site url. They have not given to original source as well._May I know how Google will consider these two pages. Which site will be affected with content duplication by Google and how can I solve this issue?If two sites put canonical tags in there own pages for the same content how the search engine will find the original site which posted fresh content. How can we avoid content duplication in this case?

Are duplicate page titles fixed by the canonical tag
Google Web Master Tools is saying that some of my pages have duplicate page titles because of pagination. However, I have implemented the canonical tag on the paginated pages which I thought would keep my site from being penalized for duplicate page titles. Is this correct? Or does canonical tag only relate to duplicate content issues?

Duplicated content on subcategory pages: how do I fix it?
Hello Everybody,
Technical SEO | | uMoR
I manage an e-commerce website and we have a duplicated content issue for subcategory. The scenario is like this: /category1/subcategory1
/category2/subcategory1
/category3/subcategory1 A single subcategory can fit multiple categories, so we have 3 different URL for the same subcategory with the same content (except of the navigation link). Which are the best practice to avoid this issue? Thank you!0 -
How can we fix duplicate title tags like these being reported in GWT?

We have over 200 pages on our site being flagged by GWT as having
duplicate title tags. The majority of them look similar to this: Title: <a>JBL EON MusicMix 16 | Mixer | CCI Solutions</a> GWT is reporting these URLs to have all the same title: /StoreFront/product/R-JBL-MUSICMIX.prod/StoreFront/product/R-JBL-MUSICMIX.prod?Origin=Category/StoreFront/product/R-JBL-MUSICMIX.prod?Origin=Footer/StoreFront/product/R-JBL-MUSICMIX.prod?Origin=Header/StoreFront/product/R-JBL-MUSICMIX.prod?origin=../StoreFront/product/R-JBL-MUSICMIX.prod?origin=GoogleBase These are all the same page. There was a time when we used these origin codes, but we stopped using them over a year ago. We also added canonical tags to every page to prevent us from having duplicate content issues. However, these origin codes are
still showing up in GWT. Is there anything we can do to fix this problem. Do we have a technical issue with our site code and the way Google is seeing our dynamic URLs? Any suggestions on how we can fix this problem? The same is true in our report for Meta descriptions. Thanks
you,

I have a ton of "duplicated content", "duplicated titles" in my website, solutions?
hi and thanks in advance, I have a Jomsocial site with 1000 users it is highly customized and as a result of the customization we did some of the pages have 5 or more different types of URLS pointing to the same page. Google has indexed 16.000 links already and the cowling report show a lot of duplicated content. this links are important for some of the functionality and are dynamically created and will continue growing, my developers offered my to create rules in robots file so a big part of this links don't get indexed but Google webmaster tools post says the following: "Google no longer recommends blocking crawler access to duplicate content on your website, whether with a robots.txt file or other methods. If search engines can't crawl pages with duplicate content, they can't automatically detect that these URLs point to the same content and will therefore effectively have to treat them as separate, unique pages. A better solution is to allow search engines to crawl these URLs, but mark them as duplicates by using the rel="canonical" link element, the URL parameter handling tool, or 301 redirects. In cases where duplicate content leads to us crawling too much of your website, you can also adjust the crawl rate setting in Webmaster Tools." here is an example of the links: | | http://anxietysocialnet.com/profile/edit-profile/salocharly http://anxietysocialnet.com/salocharly/profile http://anxietysocialnet.com/profile/preferences/salocharly http://anxietysocialnet.com/profile/salocharly http://anxietysocialnet.com/profile/privacy/salocharly http://anxietysocialnet.com/profile/edit-details/salocharly http://anxietysocialnet.com/profile/change-profile-picture/salocharly | | so the question is, is this really that bad?? what are my options? it is really a good solution to set rules in robots so big chunks of the site don't get indexed? is there any other way i can resolve this? Thanks again! Salo
