As you learn more about the best SEO practices, you’ll probably come across the term “duplicate content” at some point. And duplicate content can be malicious or not. However, one thing is for sure: it can affect your site’s ranking on the search engine results page (SERP). There are many ways to address duplicate content. One way is through the use of a duplicate content checker. In this blog post, we will talk about the best duplicate content checker tools and their benefits on your website.
What Is Duplicate Content Anyway?
According to Google Search Central, duplicate content generally refers to substantive content blocks found within or across domains. These pieces of content can either completely match other content in the same language or are appreciably similar. Most of the time, they are not deceptive in origin. However, content can be deliberately duplicated across domains to manipulate search engine rankings or win more traffic. Deceptive practices like this can result in poor user experience when visitors see the same content repeated in search results.
How Does Duplicate Content Happen?
According to Yoast, there are plenty of reasons why duplicate content happens. Most of the time, they are technical in origin. It is unusual to put the same content in two places without making clear which is the original. Below are some of these reasons:
- Misunderstanding the concept of a URL
- Session IDs
- URL parameters used for tracking and sorting
- Scrapers and content syndication
- Order of parameters
- Comment pagination
- Printer-friendly pages
- WWW vs. non-WWW
How Does Duplicate Content Affect Site Owners?
The occurrence of duplicate content can negatively affect your search rankings and significantly reduce your site’s traffic. This can happen because of diluted site visibility. Search engines rarely return multiple versions of the same content on their results page. Their algorithms will have to choose which of these versions is most likely to be the original. Search engines might mistake the copied or paraphrased version of your content to be the better one. Now, that’s bad news for you as a site owner.
Best Duplicate Content Checkers Available Online
Most search engines have a built-in duplicate content checker. Take Google Duplicate Content Checker as an example. You simply have to copy the phrase you need to check into the search box and enclose it in quotes. Google’s search results page will show you all the web pages containing that phrase. You can use this feature to make limited text queries for single terms and expressions.
However, if you have to check an entire article, this method may prove inefficient. This is where duplicate content checkers can help. Listed below are 20 of the best duplicate content checkers that offer content comparison and more in just one click.
