In the section you can find the answers to frequently asked questions about Plagiarism Checker.


  1. Why do I need to detect a text originality by Plagiarism Checker?

    Originality is a parameter expressed in a percentage and defined by special algorithms of search engines. Low originality means that a text contains a lot of fragments which match with the previously posted content on the Internet.

    And, conversely, high originality partially or fully excludes the matches.

    The high originality of a text is required due to the fact that search engines are very negative about plagiarism. The reason is that websites containing duplicate content are badly ranked by them. It means that pages which have plagiarized content cannot attract new visitors. A huge amount of plagiarism can lead to different sanctions imposed by search engines. That's why SEO specialists want to get only unique content when ordering articles for a website.

  2. How does the algorithm of Plagiarism Checker work?

    Plagiarism Checker online is the fastest way of detecting duplicate content on the Internet.

    The algorithm has advanced methods which are totally different from methods of shingles. Plagiarism Checker will detect plagiarism even:

    • after rearrangements in word order;
    • if cases, tenses, word forms were changed;
    • if new words were added to an original sentence.

  3. Where can I find my archive of checked texts?

    On the mainpage there is "Text archive" at the bottom.



    All the checked texts are stored in the archive for 30 days and then they are deleted automatically. You can also delete any text manually. The recorded texts are stored permanently. To find a text easy, you need use filters for searching by a text type, a date of checking and its accessibility.


  4. Why does a text originality decrease?

    The check results depend on different factors. The reasons for a text originality decrease:

    1. Similar content was posted on the Internet during this time.
    2. When a text was checked for plagiarism, a website containing similar content was unavailable and was not included in the results.
    3. If you rewrite news, originality can change very rapidly because other people rewrite the same news and post it on the Internet.

    Anyway, we recommend focusing on the lower originality and edit a text according to it. Open the link to your text with the lowest originality and rewrite highlighted fragments or fragments which frame them.

  5. How do I increase a text originality?

    You need a high-quality revision of a text to reach 100% originality.

    • Pay special attention to thickly highlighted fragments. Getting rid of them will help to raise your text originality.
    • We recommend deep rewriting: replacing words with their synonyms, paraphrasing, etc.

  6. What is the maximum text size for checking?

    A text for checking can contain from 100 to 15,000 characters (16-2,500 words). If it has more than 15,000 characters (2,500 words), divide it into fragments and check each one separately.

  7. After checking a text for plagiarism a text format is incorrect/spaces between words disappear. How do I avoid it?

    An incorrect format can appear when copying a text from a Word document. Texts in such document types often contain non-breaking spaces/paragraphs and hidden tags which are automatically deleted during the check and break a format. Deleting spaces and merging words can significantly affect the originality by increasing it without proper reasons.

    To avoid it, copy a text from the Word document to notepad for clearing a format and then copy a text from notepad to the checking field.
