Scribbr Plagiarism Check Guide

The process begins as soon as you complete payment. The Scribbr Plagiarism Check compares your document’s contents to billions of sources in the Ephorus database. If any of your text matches the text in a source, the relevant passage in your document will be highlighted (with a link to the source).

How to work with the results

Originality Score

1. The Originality Score


The Originality Score indicates what percentage of your document is original. The higher the score, the more original your text is.

However, a low score does not automatically mean that you have committed plagiarism. It depends on how you have cited your sources and whether you have used a correct referencing style in relation to the text in question.

2. List of matching sources

This list identifies the sources found by the Scribbr Plagiarism Check. Clicking on the links will take you to each source. The number of words found in each source text is also indicated — the higher the count, the more of your text is similar to the source text.

3. Highlighted Matches

Every similarity that is found is highlighted in your document. A similarity is a sign that you’ve copied text. Your options here are either to paraphrase the text or to present it as a direct quotation. In either case, it’s critical that you cite the source following the correct referencing style.

Working with the results

For every similarity that is found you have to decide if you have committed plagiarism, and thus if you should change the text. You can use the following course of action to do so.

1. 2. 3. 4.

Step 1: Look at the marked part of the text

The first step is to look for the similarities that were found in your document. Similar phrases have been marked orange. Next, you need to decide if these phrases are quotes or a paraphrases.

Step 2: Is it a paraphrase?

When you paraphrase, you write information from a source text in your own words. If the Scribbr Plagiarism Check shows similarities, you have probably not paraphrased correctly. If so, you should improve the way you paraphrase.

Step 2: Is it a quote?

A quote is a part of a text that you have literally copied from a source text. A quote of fewer than 40 words should always be between “quotation marks”. A quote of 40 words or more has to be in a separate block.

Step 3: Improve the paraphrase

Improve your paraphrase by using more of your own words and choose synonyms too.

Step 3: Improve the quote

You can literally copy a part of a text if you put it in quotation marks. This will then not be considered plagiarism. If you have not yet done so, place quotes in quotation marks.

Step 4: Have you used the correct referencing style?

For every quote and paraphrase you are obliged to acknowledge the source you have used. Name the source in the correct referencing style.

No guarantee

A high Originality Score is no guarantee that your thesis does not contain plagiarized content. It is merely an indicator that you can use to prevent unintentional plagiarism. It can always happen that certain sources were not found during the Scribbr Plagiarism Check. You are always the only person responsible for preventing plagiarism in your work.
