Plagiarism/Turnitin Similarity Score: How will I know what changes I need to make after I viewed the Turnitin Originality Report and how can I lower the similarity score?

Check the ‘Match Overview’ of the Originality Report
(picture shown below) and take note of sources which have more than 1%
similarity. Make changes to your text, not only to lower your overall
similarity score but also to lower the similarity of each source higher than
1%. Here are some suggestions on what you can do:
1) Remove or change strings of commonly used phrases or
text (5-8 words) such as 'Sustainability is important for the environment', as
such phrase is very common in the internet and will show up in the similarity
2) Put all exact words in quotation marks, or in an
indented paragraph. Then use the filter key in Turnitin and exclude 'quotes'
and 'bibliography'. (Refer to this link on how to use the filter function: https://help.turnitin.com/ithenticate/ithenticate-user/the-similarity-report/filters-and-exclusions.htm).
However, a better way is to paraphrase everything in your own words, even if it
is a definition, and provide the references. Make sure you don't just find
synonyms of words or change few words here and there because Turnitin can
detect similarity in sentences too.
3) Check the individual percentages of the sources. If the
percentage for one or more of the sources are 2% or more (see the example in
the picture below), reduce or paraphrase the text from that source. For
example, referring to the picture below, reduce text from Sources no. 1, 2, 3
These are some ways in which you can reduce the similarity
score, but take note that a low similarity score does not definitely mean that
your assignment is plagiarism-free. In addition to the above, you have to
ensure that you have not committed any of the possible cases of plagiarism. For
this, you have to check the EEG Part 5b. You can also refer to the attached document 'A Guide to Plagiarism - for students' on how to avoid plagiarism.
