Basically, it’s when the identical or very related content material seems at a couple of net deal with (URL).
What Is the Impression of Duplicate Content material on search engine marketing?
Google very clearly tells us that they “strive arduous to index and present pages with distinct data.”
“Our customers sometimes need to see a various cross-section of distinctive content material once they do searches. In distinction, they’re understandably aggravated once they see considerably the identical content material inside a set of search outcomes.”
Whereas any good search engine marketing ought to learn between the strains from Google, they’ve persistently emphasised the significance of distinctive content material, and we must always listen.

Web sites with duplicate content material undergo from diminished natural search visitors and fewer listed pages, and in circumstances of manipulation, they run the danger of an algorithmic penalty. That is for just a few causes:
- Do not forget that Googlebot isn’t a human. If it discovers 2 or extra pages with the identical content material, the algorithm then must resolve which web page to rank. Although they will get this proper, they will additionally get it improper.
- Spreading content material throughout a number of URLs additionally spreads constructive ‘alerts’ akin to backlinks, social shares and engagement statistics. On this means, every particular person URL advantages much less from these alerts than a single URL would.
- Duplicate content material requires Googlebot to spend extra time and assets on crawling your web site, although there’s no profit for them to take action. You’re successfully losing their time (and your web site’s crawl funds).

Natural search is barely changing into increasingly more aggressive, so we need to do the identical and current the very best, clearest model of our web site to Google so that they totally perceive it.
Widespread Causes of Duplicate Content material
Duplicate content material points can come up from quite a lot of causes. Several types of web sites akin to blogs, eCommerce web sites and many others. all include a singular set of traits that may result in duplicate content material.
Beneath, I’ll stroll you thru a few of the most typical causes of duplicate content material that I see whereas performing technical search engine marketing audits on all kinds of shopper websites. I’ll then stroll you thru tips on how to repair these points in the event you uncover them by yourself web site!
Poor Content material Administration
Whereas there are completely many technical points that trigger duplicate content material, I might be remiss to not point out checking in together with your content material supervisor first.
Actually Duplicated Content material
Often, once I first check out a web site, one of many first issues I’ll uncover is low-value, duplicate pages with URLs like:
- https://instance.com/test-page/
- https://instance.com/test-page-1/
- https://instance.com/test-page-2/
Typically, folks deliberately duplicate content material to make it simpler to create new pages with an identical format.
That is high-quality; the issue is that they neglect to scrub up.

The excellent news is these are simply mounted by merely deleting the pages and serving both a 404 or 410 standing code. However earlier than you do that, be sure that there are not any inside hyperlinks in your web site that time to those pages, to keep away from damaged hyperlinks in a while. Should you’re utilizing Seobility, you possibly can simply verify this by trying to find the URL you need to delete within the “Test a selected URL” search field:
Then navigate to the “Hyperlinks” tab, to see all incoming hyperlinks to that web page:
Duplicated Touchdown Pages
Many consumers I work with are rising their natural search channels whereas operating paid search and Fb advertisements. To make it simple to generate touchdown pages for his or her advertisements, they shortly duplicate present pages.
It’s quite common to see the next:
- https://instance.com/service/
- https://instance.com/service-lp-facebook/
- https://instance.com/service-lp-googleads/
Whereas a few of the copy used on these pages is totally different from the unique, sometimes the title, meta description, and 90% of the textual content are equivalent.
On this state of affairs, the shopper needs to rank their /service/ web page in Google, so we actually need to be clear within the message we’re sending to Google.
Any touchdown pages used for different sources of visitors can use the noindex directive, so that they gained’t be listed in Google’s index and gained’t compete with pages which might be “made for natural search.”
The exception to this rule is if we anticipate these different touchdown pages to earn social shares or backlinks. On this case, you possibly can hold the web page indexable and set the canonical URL on all touchdown pages to the principle /service/ web page as an alternative.
The canonical URL tells Google that the principle /service/ web page is the “unique” supply of the content material that ought to be displayed within the search outcomes. It can additionally consolidate the constructive alerts coming from backlinks to the canonical web page.
Within the instance above, we would want so as to add this canonical tag to all the duplicated touchdown pages:
Should you use this methodology, do not forget that a web page shouldn’t be noindexed whereas pointing to a special canonical URL, to keep away from sending blended alerts to Google.
Google search advocate John Mueller confirms this:
“…you shouldn’t combine noindex & rel=canonical…they’re very contradictory items of data for us. We’ll typically choose the rel=canonical and use that over the noindex, however any time you depend on interpretation by a pc script, you scale back the load of your enter.”
Incorrect Server Configuration
Google formally introduced that HTTPS was a rating issue again in 2014, and in 2018, Google Chrome started marking net pages loaded over HTTP as “not safe”.
All web sites ought to be secured, which is defined in additional element on this information on switching from HTTP to HTTPS.
For a lot of websites served over HTTPS nevertheless, an all too frequent explanation for duplication comes from an absence of redirects, which permits the identical piece of content material to be seen at 2 or extra URLs.
In easy phrases, in case your web site is accessible by means of each HTTP and HTTPS, with no redirects between the 2 variations, it will lead to duplicate content material. And never only for one web page, however for all of the sub-pages in your whole web site!
Your web site shouldn’t be out there at https://instance.com and http://instance.com.
Equally, it shouldn’t be out there on a subdomain in addition to the basis area, akin to https://www.instance.com and https://instance.com.
However even when you have your area dealing with sorted out, there are different culprits that may result in duplication points, akin to a easy trailing slash being hooked up to your URLs. https://instance.com/service shouldn’t be out there at https://instance.com/service/, and vice-versa.
For all of those eventualities, it’s vital to have redirects in place that robotically redirect guests to your one most popular URL variant. This could at all times be the HTTPS model to supply a safe connection for all web site guests. From there, you’ll must resolve tips on how to arrange your subdomains (www or non-www generally) and permalinks (with or with no trailing slash).
My most popular answer is to arrange web sites with out www, and at all times with a trailing slash.
Should you’re undecided whether or not these redirects are configured accurately in your web site, Seobility’s free Redirect Checker will allow you to discover out:
Simply enter your area and choose your most popular URL format and the software will robotically verify in case your https/www redirects work as supposed.
On the backside of the outcomes web page, you’ll additionally discover a Redirect Generator that can generate the required code to repeat and paste into your .htaccess file on Apache or NGINX server config to arrange these guidelines accurately, if that’s not already the case.
Along with establishing the redirects accurately, you also needs to be sure that the canonical tags are right.
They usually get missed, however in the event you’re utilizing HTTPS and your canonical tag factors to HTTP, Google will index HTTP. The difficulty is that if HTTP then additionally redirects to HTTPS, it creates an infinite loop, which doesn’t please Google.
On WordPress, the preferred search engine marketing plugins, like Yoast and Rankmath, will possible change the canonical tags robotically once you change from HTTP to HTTPS. Nevertheless, you may need to vary the principle web site deal with URL within the settings.
Should you’re not utilizing an search engine marketing plugin, you’ll want so as to add/edit the canonical tags manually. They need to be added inside the
part of your HTML and level to the HTTPS model of every web page.
For instance, the web page https://instance.com/page-1 ought to have a self-referential canonical tag pointing to https://instance.com/page-1 (i.e. the identical URL) to make it clear that that is the web page you need Google to index.
Multi-Language Administration Points
In an identical vein to content material administration, a whole lot of content material websites have points with duplicate content material because of partially or wholly un-translated content material.
Should you use WordPress, you is likely to be conversant in multi-language plugins like Polylang and WPML. These plugins make it simple to clone present content material in your main language with the intention of translating it into a brand new language.
In lots of circumstances although, content material is usually cloned and forgotten about, as crew members don’t usually browse the location in a special language. Blocks of content material, and even whole pages and weblog posts find yourself being out there in English, regardless of the web page’s hreflang denoting a special language.
If you’re utilizing certainly one of these plugins, take the time to evaluation every web page and publish of content material, in every language to make sure that 100% of it’s translated. Seobility’s Duplicate Content material Evaluation can prevent a whole lot of time right here, particularly when you have 1000’s of URLs value of content material (extra on this later).
After discovering untranslated content material, both process your content material crew with translating it, translate it robotically, or think about deleting that piece of untranslated content material within the particular language.
Should you resolve to delete the content material solely, be sure to:
- Take away or change any inside hyperlinks pointing to the content material (as defined within the part “Actually Duplicated Content material”)
- Regulate hreflang hyperlinks out of your multi-language plugin dashboard
- Replace your sitemap if essential to replicate Google the adjustments you’ve made
Product Pages on eCommerce Web sites
Ecommerce search engine marketing managers have gotten more and more detail-oriented, however for the longest time auto-generated product pages primarily based on imported product listings was the secret.
In product ranges with numerous variations, akin to automotive components or clothes, duplicate content material could be frequent.
Right here’s an instance from the wild:
Each single product variation has a special URL. Although the title is partially distinctive, the picture and product descriptions are equivalent.
Whereas one may argue that particular person merchandise may rank for very particular long-tail key phrases (and that’s true), let’s be actual – in the event you’re not taking the care to supply distinctive product data on every web page, it’s not going to carry out.
This web site proprietor is much better off with a single product URL that gives 12 variations by way of a drop-down menu.
For extra data on tips on how to optimize your eCommerce web site’s product pages, together with tips on how to deal with related merchandise in addition to product variations, take a look at Seobility’s in-depth information on search engine marketing for eCommerce product pages.
Pagination is a way used to divide massive teams of content material into a number of pages. Image the weblog dwelling web page on a web site that has 2,500 weblog posts or an ecommerce web site with 200 merchandise in every of its 12 classes.
As a substitute of loading all of the content material in a single, prolonged web page that’s sluggish to load and has too many hyperlinks, pagination permits customers to navigate by means of smaller, extra manageable chunks of content material.
By clicking by means of lists of posts or merchandise by way of hyperlinks (sometimes numbered) on the backside of every web page, consumer expertise, web site velocity, and search engine marketing are improved. Google itself offers a very good instance of this on its outcomes pages:
Generally although, paginated class pages might have a prolonged introduction block on the web page or supporting content material under the product record, and that is repeated each time it’s paginated, creating duplicate content material.
To keep away from this, ask your self if you actually need pagination within the first place. If the content material can simply be displayed on one web page with out affecting load instances and consumer expertise, then you need to go for it, as it is going to take away a whole lot of complexity out of your web site.
Nevertheless, when you have a whole lot or 1000’s of things in a class, this gained’t be an possibility.
On this case, you need to solely use the content material on web page 1 of your pagination and take away it from all subsequent pages. This won’t solely keep away from duplicate content material, however can even give Google an vital trace to show web page 1 of your pagination in its search outcomes, fairly than selecting one other web page. To additional scale back the chance of Google displaying web page 4 or 5 of your pagination as an alternative of web page 1, you possibly can “de-optimize” the paginated pages, for instance by selecting a title akin to “Outcomes web page 4 of class …”.
If this isn’t attainable because of technical limitations of your CMS or related causes, an various answer is to set all pages ranging from web page 2 of your pagination to noindex. Nevertheless, this answer has a significant downside: Google will finally cease following all hyperlinks on noindexed pages. Which means when you have vital hyperlinks in your paginated pages (e.g. hyperlinks to product pages), it’s worthwhile to be sure that Google can entry the linked pages in different methods earlier than implementing this answer, e.g. by offering an optimized XML Sitemap that features these hyperlinks.
One methodology of coping with paginated content material that’s typically advised by SEOs, however which Google doesn’t advocate, is to set the canonical tag on pages 2, 3, and many others. to the primary web page of the pagination. The aim of this methodology is to get the primary web page listed by Google and to consolidate all of the constructive rating alerts on that first web page whereas avoiding points like duplicate content material. Nevertheless, this isn’t what canonical tags are supposed for. Should you use them on this means, this may sign to Google that you’ve just one class web page, fairly than a paginated collection, and in consequence it could not uncover the pages listed on web page 2, 3, and so forth.
If you wish to dig deeper into this subject, this information on SEJ offers a terrific overview of search engine marketing finest practices in addition to frequent myths about pagination.
Tags, Classes and Writer Archives on WordPress Web sites
Certainly one of my favourite optimization alternatives on WordPress websites is to show shut consideration to tags, classes and writer archives.
It’s certainly one of many actions we evaluation when operating by means of our “search engine marketing launchpad” course of at Dialed Labs. None of those are inherently dangerous. It’s solely that they’re recurrently misused or produce very low-value pages.
Skinny Content material in Archives
Whereas this isn’t immediately associated to duplicate content material, it’s one thing that must be talked about when speaking about archive pages on WordPress web sites.
Each classes and tags are nice methods to prepare and categorize weblog posts. However many web site homeowners and content material creators are unaware that WordPress robotically creates an archive web page for every new class and tag they create.
Classes are extra intuitive, so that they appear to be used accurately on most websites. Tags, then again, appear to be seen as some form of search engine marketing powerup, the place folks attempt to use as many as attainable on their posts.
Consequently, quite a few websites find yourself with an extreme variety of tags, resulting in numerous pages with skinny content material that supply subsequent to no worth.
This apply might stem from the outdated notion that “extra pages equal higher visibility.” I disagree. A small, highly effective web site that’s filled with high-value pages is my choice any day!
If this downside sounds acquainted to you, take into consideration which tags you actually need on your web site and hold solely these. When you have tags that solely include 1-2 articles, readers who need to discover extra of your web site’s content material gained’t discover a lot worth in these tags.
Tags that don’t add worth to guests could be deleted solely, however be sure to redirect the URLs to an identical web page if they’ve exterior hyperlinks pointing to them.
Should you don’t need to delete the pages, you may as well think about setting them to noindex. The preferred WordPress search engine marketing plugins, akin to Yoast search engine marketing and Rankmath, make it simple to noindex these pages from their plugin settings.
An exception to the noindex rule is when the archive pages are incomes natural visitors on their very own. For instance, your writer is likely to be a well-known writer whose identify will get searched naturally. In circumstances like this, you need to hold the web page listed to proceed gaining visitors from Google.
Duplicate Content material in Archives
As if skinny content material wasn’t sufficient, archive pages also can result in duplicate content material points if not dealt with correctly.
In web site themes that don’t restrict archive pages to utilizing solely an excerpt of content material, weblog content material could be displayed in its entirety on the house web page, in an writer archive, class archive and a number of tag archives earlier than we even think about the precise publish URL.
An exception to the noindex rule is when the archive pages are incomes natural visitors on their very own. For instance, your writer is likely to be a well-known writer whose identify will get searched naturally. In circumstances like this, you need to hold the web page listed to proceed gaining visitors from Google.
The above picture reveals when an writer web page is displaying an excessive amount of of the article content material (no excerpt restrict), resulting in duplicate content material points.
Any content material displayed on class/writer/tag archive pages ought to solely use a small excerpt to keep away from duplication. You are able to do this by utilizing the built-in ”Extra” block” in WordPress, which can robotically make the excerpt solely 10-25 phrases. For the earlier picture, that is how the distinction would seem like:
One other explanation for duplicates in archive pages are redundant tags and classes. For instance, in the event you run a digital advertising weblog and you’ve got a class referred to as ‘content material advertising’, however you additionally create a tag for ‘content material advertising ideas’, then each pages are more likely to include the identical articles, leading to duplicate content material.
To keep away from this, be sure to use distinctive tags and classes that don’t repeat one another and hold this categorization system as clear as attainable. Your classes ought to be extra normal and point out the broad subject of your posts, whereas tags are normally extra particular and assist folks discover related content material after studying certainly one of your posts.
In case your web site already suffers from duplicate content material points because of redundant classes and tags, it’s time for a clear up. As described within the part “Skinny Content material in Archives”, take into consideration which of those pages you actually need and delete / noindex all the pieces that doesn’t present worth.
