Drupal 8 Duplicate Content

The Global Redirect module can painlessly eliminate duplicate content on your Drupal website

A while back, Ben Finklea wrote about how easy it is to accidentally create duplicate content, and how to fix it. Though it has been some time since the post went up, it remains popular and useful advice— so we wanted to share it with you again.

Duplicate content isn’t just annoying and inconvenient— it’s bad for your SEO, and it’s very easy to accidentally create duplicate content on a Drupal site. But what is duplicate content? According to Google, duplicate content is “substantive blocks of content within or across domains that either completely match other content or are appreciably similar.”

Practical-seo-with-drupal-8 The latter examples shed unnecessary fill words and are much friendlier to read, they also leverage the use of main keywords. With the Pathauto module in Drupal 8 we can easily create patterns when generating new content, and while this is excellent and we recommend Pathauto for use on the site, this doesn’t mean. I think the simplest will be to duplicate it and start working on it. It seems there is no official way to clone a content type in Drupal 7. Edit 2: The official release of Content Type Clone for Drupal 8 is available on the same page. Improve this answer. Follow edited Oct 27 '17 at 15:46. Does Google's 'duplicate content penalty' harm Drupal sites? For years, Drupal has enjoyed a solid reputation as a search engine friendly CMS. It generates relatively clean, standards-compliant HTML out of the box; syncs up the important TITLE tag with semantically useful H1 and H2 tags in the body of each page; and provides.


(In layman’s terms, duplicate content is content on your website that’s really, really similar, if not identical, to other content on your website or even elsewhere on the web.)

Some duplicate content is malicious: spammers stealing your website’s content and posting it as their own is malicious duplicate content, for example. However, the most duplicate content that we find (by far) is non-malicious duplicate content, such as:

I tried using the 'Distinct' option in the query settings, which eliminated most of the duplicates. However, Views continues to duplicate random content. Some content will have no duplicates, some content has multiple duplicates. I've also tried using aggregation, but Views will not output anything when I.

  • Discussion forums that can generate both regular and stripped-down pages targeted at mobile devices.
  • Store items shown or linked via multiple distinct URLs
  • Printer-only versions of web pages

Unfortunately, when this happens, it can hurt your rankings: Google can’t figure out which duplicate content is the original source, and your content winds up competing against itself. For websites that have multiple pages with very similar content, there are certainly ways to indicate your preferred URL to Google— and for Drupal websites that have duplicate content, one of the best ways to fix the problem is by installing and using the Global Redirect module.

The Global Redirect Module

The Global Redirect module will take care of some housekeeping issues that come up when clean URLs are enabled in Drupal. In short, it’ll eliminate some of the duplicate content issues that you may not have known you had.

Here’s an example from Ben.

'Let’s say, for example, that you create a new website and create the first node that you call the About Us page. Later, because you want the front page of your site to be the content of that node, you go into site settings and make node/1 the front page of the site. Sounds pretty harmless, right? Well, right at this moment, all of these URLs on your site would show the exact same content:

The search engines will think that you have six pages of the exact same content. That's never good. Global Redirect fixes that by redirecting all the URLs you don't want to the one URL that you do.'

The Global Redirect does a few neat tricks to make this happen. According to the module’s homepage on Drupal.org, it:

  • Checks the current URL for an alias and does a 301 redirect to it if it is not being used.
  • Checks the current URL for a trailing slash, removes it if present, and repeats check 1 with the new request.
  • Checks if the current URL is the same as the site_frontpage and redirects to the frontpage if there is a match.
  • Checks if the Clean URLs feature is enabled and then checks the current URL is being accessed using the clean method rather than the unclean method.
  • Checks access to the URL. If the user does not have access to the path, then no redirects are done. This helps avoid exposing private aliased nodes.
  • Make sure the case of the URL being accessed is the same as the one set by the author/administrator. For example, if you set the alias 'articles/cake-making' to node/123, then the user can access the alias with any combination of case.

For those who want to install it, but aren’t that technical, it’s pretty easy: download the module from https://www.drupal.org/project/globalredirect and configure by navigating to http://www.yourDrupalsite.com/settings/globalredirect or clicking on Admin Site configuration Global Redirect

Some of your options will include the following:

  • Deslash: Set to On. If enabled, this option will remove the trailing slash from requests. If you require certain requests to have a trailing slash, this feature can cause problems and so may need to be disabled— otherwise, leave it on.
  • Non-clean to Clean: Set to On. If enabled, this option will redirect from Non-clean to Clean URL (if Clean URL's are enabled). This will stop, for example, node 1 existing on both yourDrupalsite.com/node/1 and yourDrupalsite. com?q=node/1.
  • Remove Trailing Zero Argument: Set to Disabled. If enabled, any instance of /0 will be trimmed from the right of the URL. This stops duplicate pages such as taxonomy/ term/1 and taxonomy/term/1/0 where 0 is the default depth. There is an option of limiting this feature to taxonomy term pages only or allowing it to affect any page. By default this feature is disabled to avoid any unexpected behavior.
  • Menu Access Checking: Set to Disabled. If enabled, the module will check the user has access to the page before redirecting. This helps to stop redirection on protected pages and avoids giving away secret URL's. By default this feature is disabled to avoid any unexpected behavior.
  • Case Sensitive URL Checking: Set to Enabled. If enabled, the module will compare the current URL to the alias stored in the system. If there are any differences in case then the user will be redirected to the correct URL. Click Save configuration. Now your site is protected from duplicate content.
