What Do Journal Rankings Mean? Research Impact & Journal Ranking Lists

When stepping into postgraduate studies, you may often hear about journal rankings and how publishing in a ‘Q1’ journal means something prestigious. What do journal rankings mean, and in what ways do it matter?

Journal rankings is a system where academic journals get measured for quality, impact, and influence. Highly ranked journals are impactful, with its articles frequently cited in other papers. Journals may be grouped in quartiles, named Q1 to Q4. 

This article explores what do journal rankings mean, and how they impact research. We also explain common terms you may hear in this area, such as quartiles, impact factors, and more.

What Are Journal Rankings?

What do journal rankings mean in the world of academic publishing? Journal ranking lists categorize journals based on their:

• impact factor,
• citation metrics, and
• other factors that measure quality and influence.

Metrics like the impact factor or SJR (Scimago Journal Rank) tell you the average number of citations an article receives within a journal.

This can hint at its “prestige” but can also mislead, especially when comparing journals in different fields where citation norms vary widely.

These systems may seem coldly calculated, but they reflect more than numbers—they:

• shape careers,
• drive funding,
• salaries, and
• influence where research gets published. 

Whether you’re a researcher, academic, dean, or student, knowing how to navigate journal ranking lists can make all the difference in academia.

How Are Journal Rankings Measured?

Talking about what do journal rankings mean also means looking at how they are measured.

Measuring journal rankings come down to a few key metrics, each with its own quirks and impacts on the academic journal ranking lists.

Journal Impact Factor

First is the Impact Factor (IF), the classic metric from Clarivate’s Journal Citation Reports (JCR).

It calculates the average number of citations per article over two years, ranking journals based on their “citation impact.”

But beware: journals in fields with fewer citations or longer publication cycles might rank lower despite their quality.

For example, a humanities journal might score lower than a medical one, simply because of citation norms. 

Scimago Journal Rank (SJR)

SJR doesn’t just count citations—it weighs them, giving more value to citations from highly-ranked journals. SJR, powered by Scopus, gives a fuller picture of a journal’s prestige across academic fields.

A top SJR-ranked journal, like The Lancet, often signals more influence within its category than a high IF alone.

H-index (Google Scholar)

H-Index focuses on an author’s or journal’s productivity and citation impact over time.

A journal with an h-index of 20 means it has 20 articles cited at least 20 times each.

Google Scholar Metrics leverages the h5-index for a five-year look at a journal’s citation performance, making it popular in academic institutions and national rankings, especially for assessing emerging fields.

Eigenfactor Score

Another metric, the Eigenfactor Score, builds on citation impact by excluding self-citations and weighing citations by the “importance” of the citing journal.

The Eigenfactor score, created by the University of Washington, even considers the time researchers spend reading journals.

It’s an insider’s metric, sometimes overlooked, but highly influential, especially in research institutions focused on more granular journal impact.

CiteScore

Then there’s CiteScore by Elsevier, which extends the impact factor’s time frame, measuring citations over four years instead of two.

Journals in fields with slower citation cycles, like social sciences, often perform better here.

You’ll find that a journal with a modest impact factor might look more influential under CiteScore, especially in broader ranking lists.

What Are Journal Quartile Ranking Systems?

When exploring the subject what do journal rankings mean, you cannot not talk about quartile systems.

The quartile system, used in Scopus and Journal Citation Reports (JCR), categorizes academic journals into four levels, or quartiles.

In this ranking list, a “Q1” journal ranks within the top 25% of journals in its field.

Q1 journals often enjoy high prestige and visibility, making them a prime choice for publishing high-impact research.

The quartiles continue with Q2, Q3, and Q4, each representing the next 25% of journals within a subject area.

• Q1 – top 25% journals
• Q2 – 26-50% of journals
• Q3 – 51-75% of journals
• Q4 – the remaining journals.

This system helps researchers, deans, and institutions quickly assess journal quality and impact.

If you’re targeting journals in the same field, Q1 publications are widely recognized as benchmarks of high citation impact and visibility.

Scimago’s SJR rankings use the quartile system based on weighted citations, meaning that Q1 journals here don’t just have many citations—they have citations from influential sources.

The quartile ranking gives you insight into a journal’s standing without getting lost in metrics like impact factor.

But it’s important to remember that a Q1 journal in one field doesn’t compare directly to a Q1 in another. Each discipline has its own citation culture, which can affect rankings.

So when you’re looking to publish, the quartile ranking can be a guide but needs to be considered alongside other factors.

Where Do You Find Journal Ranking Lists?

Here are three essential sources to find journal ranking lists. Each offers its own approach to ranking academic journals, letting you compare them from different perspectives.

Journal Citation Reports (JCR) by Clarivate

The is a classic choice. It ranks journals by impact factor and is widely used by academic institutions.

Its impact factor-based system focuses on citation counts over two years, helping you understand a journal’s immediate influence.

Scimago Journal Rank (SJR)

Based on Scopus data, SJR uses a different ranking system. It’s great for exploring journals outside the JCR, especially in emerging fields. 

Scimago’s SJR weighs citations by the rank of the citing journal, which adds a layer of prestige. You’ll also find quartile rankings here, making it easy to find high-ranking journals in your subject area.

Google Scholar Metrics

For a broader range of journals, Google Scholar Metrics offers another option. Using the h5-index, it ranks journals by citation impact over five years.

Google Scholar Metrics can be useful if you’re looking for national rankings or if you want to compare journals based on longer-term citation trends across more fields. 

Are Academic Journal Rankings Separated by Types Of Journals?

Are academic journal rankings separated by types of journals? Absolutely.

The best ranking systems, like Clarivate’s Journal Citation Reports (JCR) and Scimago Journal Rank (SJR), divide journals by subject categories to provide accurate comparisons.

This separation matters. A high impact factor in medicine, where citations are frequent, won’t hold the same meaning in sociology, where citation counts grow more slowly.

That’s why JCR and Scimago assign journals to subject-specific quartiles (Q1, Q2, etc.) within their respective fields. This lets you see the real standing of a journal compared to others of the same type.

Scopus and SJR go further by adding “country rank” and category-based analysis. This helps you find journals within regional contexts or in narrower fields.

A “Q1” journal in environmental sciences could be global or nationally ranked, depending on how metrics like citation counts are calculated.

What Do Journal Rankings Mean? Explored & Explained

So, what do journal rankings mean? It is a way to measure research impact, and decide how journals are positioned within academic fields.

While each ranking system works slightly differently, using multiple metrics offers a more complete view of a journal’s quality. 

Ultimately, these rankings don’t just reflect prestige—they shape academic careers, funding decisions, and the future direction of research in critical fields.
