• Citation influence

However, institutional policies vary.

Scopus Quartiles vs Web of Science Quartiles

Scopus Quartiles

Based on:

• CiteScore
• SJR

Categories:

• Q1
• Q2
• Q3
• Q4

Q1 journals represent the top-performing journals within a field.

Web of Science Quartiles

Based on:

• Journal Impact Factor
• Journal Citation Reports

Similarly categorized as:

• Q1
• Q2
• Q3
• Q4

Researchers often target Q1 journals for maximum academic impact.
