In this tech-driven world, the easy accessibility of data has given birth to rising cases of plagiarism. It is a pressing concern for people operating in academia and the web, as it takes away the essence of producing authentic and original work. 

The universities demand original assignments from students in order to help them develop skills that can pay off in professional careers. On the other hand, website owners require unique content that can improve their conversions.

Dealing with instances of duplication was quite difficult. However, you can rely on a free online plagiarism checker. Here a question arises which checker you should use to ensure originality in the textual content. This query can be resolved by going through this blog till the end. 

In this blog, we will discuss how plagiarism checkers work and what you should be looking into while searching for a reliable utility. So let’s dive and explore everything about it.


The checkers utilize various technologies to deliver top-notch results. It’s essential to understand these aspects, as it will help you in the selection of the right tool. The working of these tools involves the following processes.

Multi-Layered Search

Mostly, the duplicate checkers are limited to a narrow database that isn’t enough to detect potential plagiarism. The small databases don’t allow these detectors to identify the matching text. Therefore, you should look for a comprehensive database tool that covers all types of content. 

SmallSEOTools’ best free plagiarism checker comes with a multi-layered search capability, which gives access to multiple databases while conducting a similarity check on your submitted document. This technology goes beyond web sources and allows users to authenticate their work through additional databases that consist of research publications, books, journals, and various other sources.

Deep Search

Many students and professionals make attempts to disguise duplication by manipulating words in the original text. Mostly, checkers aren’t able to detect such manipulations and make the users believe that the text is unique. 

However, the deep search technology used by SmallSEOTools combats this nuisance, as it uses natural language processing. It conducts an in-depth analysis of the entered text to match it with the data available in databases on the basis of context.

The plagiarism score generated through this technology evaluates the overall context of any text to provide you with accurate results. The universities check the students’ work thoroughly with a detector offering in-depth search technology, as they are well aware of the act of removing duplication. 


When trying out multiple online tools, you’ll find one thing common in them, i.e., flagging the exact matching phrases, sentences, and paragraphs. However, limiting yourself to this detection will never let you see a work’s originality clearly. 

Paraphrasing methods are popular among students to alter text and prevent their work from being detected as plagiarized. But in order to deal with this issue, the fingerprinting process is gaining popularity among advanced checkers. 

Plagiarism detector offered by SmallSEOTools uses this technology to find matching fingerprints of your documents from the text available in its databases. If the fingerprints in your text don’t match any other source’s fingerprints, it will be declared unique. Otherwise, it will let you know the places where duplication has been detected in your text.

Stylometry is the latest technology being adopted by duplication detectors, as it provides the ability to detect identical writing styles. It’s common among educators to look for similarities in the style of written assignments.

 However, when doing it on your own, it requires ample time and still doesn’t return satisfactory results. That’s the reason behind introducing stylometry in the advanced plagiarism detection tools. If the work submitted by a student contains text that follows different styles, the tool will flag that as plagiarized.

Final Thoughts

Every tool you find is based on different technologies; hence, it can be concluded that it won’t be right to say that all detection tools have the same functionality. When exploring different options, you should look into the aspects discussed above to select the right tool for identifying plagiarism. 

It’s recommended not to stick with a tool that only carries out a simple string-matching process, as you can also do it on your own by entering your text on Google or other search engines.

 If you wish to stay away from the nuisance of plagiarism, it’s essential to find a tool that has a comprehensive database and possesses the ability to detect contextual duplication as well!
