Scopus is a global ecosystem that brings together an impressive amount of quality scientific content. Thousands of prestigious publications are indexed in the database, and in order to divide them by indicators of influence, a ranking system - quartile - was introduced. Why is this ranking so important and which Quartile to choose for publishing a scientific paper? Answers to these questions will be given in today's review.

What is a journal quartile in Scopus?
A quartile is a system for ranking scientific journals into groups based on their citations and influence in their field. The distribution of journals into quartiles is based on the CiteScore, which reflects the average number of citations received by articles published in the journal over the last four years.
Q1, Q2, Q3 and Q4 - what is the difference?
Q1 journals
Publications in the first quartile have the greatest impact in Scopus. These journals are in the top 25% of the best journals in a particular subject area. Publication in a Q1 journal maximizes the visibility and scientific impact of your work, making it accessible to a wide audience. However, due to high competition, the acceptance rate of articles in such journals is usually low, which emphasizes their prestige and strict selection criteria. Publishing in this category of journals offers many advantages to the scientist: high visibility of published work, a higher probability of citations, increased prestige and a positive impact on career.
Who is suitable for publishing in Q1 journals: docents and professors, experienced researchers who have a long academic record. Publication in first quartile journals is suitable for scientists who seek to gain international recognition and build a reputation in the global scientific arena.
Q2 journals
Scientific publications that occupy between 25% and 50% of their fields of expertise. Less competitive for authors compared to Q1 journals, but also characterized by high impact. Q2 journals have a higher acceptance rate than Q1 and less stringent selection criteria. Publishing in a Q2 journal is a good way to increase the visibility of one's work, especially for those who seek recognition in their field without having to go through the toughest competition typical of Q1 journals.
Who is suitable for publication in Q2 journals: Doctors and professors can also publish articles in highly ranked second-quartile publications. Q2 journals, although inferior to Q1 journals, are still highly influential in academia. Publishing in Q2 journals is suitable for academics who want a stable level of visibility and recognition for their work, but are willing to make a reasonable trade-off in terms of competition and citations.
Q3 journals
Q3 journals range from 51% to 75% in terms of citation rates. Although their impact is lower compared to Q1 and Q2 journals, they play an important role for researchers seeking to publish their work and increase their citations. Third quartile journals indexed in Scopus are often more specialized, making them attractive for publishing narrowly focused research. In addition, these publications provide an excellent opportunity for early career researchers to take their first steps in the academic world and gain experience publishing in international publications.
Who can benefit from publishing in Q3: this category of journals will be a good career start for young scientists and will help to make a name for themselves in the international scientific community. Publication in Q3 is suitable for PhDs and postdocs who are planning to get the scientific rank of associate professor or professor.
Q4 journals
Q4 journals make up the bottom 25% of publications indexed in Scopus. This is the category of newer publications that have the lowest impact and number of citations. Although these journals do not have the same prestige as Q1-Q3 journals, they still provide good opportunities for publication, especially for highly specialized or new areas of research. For early career researchers or those working on under-researched topics, Q4 journals can be a good start to a research career. Fourth quartile journals are the least demanding and have a high acceptance rate.
Who can benefit from publishing in Q4 journals: Young scientists who are just starting their scientific career and want to gain experience in publishing in international databases (PhDs, postdoctoral fellows).
