What Are the Best Tools for Checking Duplicate Content?

Because the internet is filled with endless articles, you may come across different web pages with the same topic. Though there’s nothing wrong with talking about similar subjects, it isn’t acceptable to replicate something word for word. In simpler terms, duplicate content is described as any identical body of text that is published on more than one site. The inability of a website to have original writing is already a form of plagiarism. And, plagiarism – from an academic perspective – is defined as having more than  words that are exactly the same as in another text.

Although plagiarism is a minor offense against the law, you can suffer massive consequences. Search engines such as Google have low tolerance for content copied word-for-word. Not only do they have the power to lower your website’s ranking, but they might even take out your website altogether from their search engine if it’s egregious enough.

This is crucial to website owners because most web traffic is collected through search engines, and web traffic is key to a website’s success.

The Importance of Original Content

Another key to making your website successful is by maintaining authenticity. A problem search engines face with duplicate content is that they are unable to determine the original source. You can’t be certain whether they are giving credit to the rightful owner. This has always been a problem – in fact, recently, an SEO content exposed weaknesses in Google’s algorithm – one SEO was able to rank “Lorem ipsum,” text, or dummy text.

The bottom line is that search engines want to give their users a trouble-free experience so that they will continue to use their services.

Original content gives your website natural credibility. People are more willing to credit you as a source, whereas websites with heavy syndication of RSS feeds are often frowned upon since most of their content is composed of “copy-paste” text. While not outright plagiarism when attribution is fully credited and permission is obtained from the author, it is still unsavory.

Life without duplicate content makes life better for everyone as websites are given the recognition they deserve. Researchers can easily navigate through websites to discover other information about a topic. Lastly, search engines provide more resourceful results.

Avoiding Duplication

Just as it isn’t wrong to write about the same topic as another published article, using websites as resources is still acceptable.

Although it isn’t in your intention to copy a certain article, your mind could unconsciously rewrite identical content. To avoid any context collisions, you can access anti-plagiarism tools.

Top 10 Tools for Duplicate Content

Aside from publishers, many teachers and students use plagiarism tools to check if a composition is credible and original. Here is a list of popular tools used on how to check duplicate content:
