Duplicate content is content that appears on the internet in more than one place. That “one place” is a unique website address or URL so, if your site has the same or “appreciably similar” content as Google refers to it then you’ve got duplicate content.
Duplicate content can cause problems because if you have multiple versions of the same page it can be difficult for search engines to decide which version of the page is the most relevant for a given search query. This can lead to negative impacts on your rankings in search results which is why duplicate content warnings should be dealt with quickly.
Why Worry About Duplicate Content?
Duplicate content causes problems for both search engines and for site owners according to Moz. The three main problems it causes for search engines are:
Search engines don’t know which versions of a page to include in the index and which versions to exclude.
Search engines don’t know whether to direct link metrics to one version of the page or divide the metrics between the different versions of the page.
Search engines don’t know which version to rank for query results.
Duplicate content causes two main problems for site owners as well:
The goal of search engines is to try to provide the best experience possible for a search engine user which means that search engines almost never show multiple version of the same content. This dilutes the visibility of duplicate version of a page because search engines won’t include them in search results.
Other web sites will have a hard time determining which page they should link to if you have multiple versions of the same page. Rather than having a single high-quality page with multiple inbound links, which is a major ranking factor, your inbound links are spread our among different identical pages which dilutes the impact of them.
What Causes Duplicate Content?
Duplicate content is rarely created on purpose by website owners. Despite this, there is still a ton of duplicate content out there on the internet. Two of the most common ways duplicate content ends up on websites are:
HTTP vs. HTTPS pages –If your site has two separate versions, one that starts with http:// and one that starts with https://, and both sites are live with the same content then you have effectively created duplicates of all of those pages.
Copied content – This applies to more than just your blog posts and other editorial content. If you are an e-commerce website and you use manufacturers’ descriptions for products on your site you could have the exact same content as other sites selling the same items. Google could then view your page and a page on another site as duplicates of one another.
Thin Content vs. Duplicate Content
Thin content warnings, like the example below, can have a negative impact on your rankings as well. Thin content is content on your site that has little to no value to a user. When you think thin content think pages like low-quality affiliate pages or doorway pages that are meant to manipulate search engine rankings and get a user onto a site but offer very little value beyond that. If you are dinged for thin content on your site make sure to improve your pages that seem light on content so that you don’t risk harming your ranking or having your site removed from search engine indexes.
How to Fix Duplicate Content Issues
There are many ways to fix duplicate content issues but they all function on the same central idea: telling search engines which of the duplicate pages is the “correct” one.
If you have content on your site that exists on multiple different URLs there are a few simple tools that you can use to fix the possible problems associated with duplicate content.
Redirect duplicate pages to the original page – The easiest way to avoid problems with duplicate content is to redirect duplicate pages to the page you want to be considered the original. This tells the search engine which page should be ranked and will also transfer the positive ranking factors of duplicate pages to the original page as well.
Canonical linking – Setting up a canonical link is similar to redirecting a page. Basically canonical links tell a search engine that a given page is a copy of a different page and that the search engine should rank the original page instead. Canonical links are also written directly into the head of the page so they require little time to implement.
Noindex duplicate pages – Noindexing also only requires a simple tag in the head of your duplicate page. Pasting the HTML code tells search engines that you don’t want the specific page indexed so there’s no chance that it will compete with your other pages for rankings.
