What Is a Scopus Journal? A Complete Guide for Researchers
A Scopus journal is a journal that has been formally reviewed and accepted by Elsevier's Content Selection & Advisory Board (CSAB) for inclusion in Scopus, one of the world's largest curated abstract-and-citation databases. Being a Scopus journal is not automatic or self-declared. It is an ongoing status. A journal earns it, keeps it only by meeting quality standards, and can lose it.
That distinction matters more than most researchers realize. Anyone can print "Scopus indexed" on a journal website. Whether it's true is a separate, verifiable fact. This guide exists so you can check it yourself in under five minutes, rather than taking a journal's word for it.
Key Takeaways
"Scopus-indexed" means a journal passed a formal review by Scopus's independent Content Selection & Advisory Board; it is not a self-assigned label.
Indexing is genuinely selective: Elsevier states that of the thousands of titles suggested to Scopus each year, only about a third pass initial technical screening, and only half of those are ultimately accepted (Elsevier, "Scopus content," July 2025).
You can verify any journal's real status yourself, free, at scopus.com/sources; never rely on a journal's own claim.
CiteScore, SJR, and SNIP are three different (and easily confused) impact metrics Scopus publishes, each measuring something distinct.
Dual indexing in both Scopus and Web of Science is uncommon and a stronger credibility signal than either alone.

Why Dual Indexing in Scopus and Web of Science Is Rare and Valuable
What Is Scopus?
Scopus is Elsevier's abstract-and-citation database of peer-reviewed literature (journals, book series, conference proceedings, and trade publications), used by researchers, universities, funding bodies, and publishers to track citations, measure journal impact, and evaluate research output. It currently draws content from more than 7,000 publishers across roughly 330 subject disciplines, with more than 217,000 indexed book titles and over 2.4 billion cited references, some reaching back to 1788 (Elsevier, "Scopus content," current as of July 2025).
It is not a publisher, a journal, or a certification body in the way "ISO certified" implies a one-time audit. It's closer to a curated library catalog: Scopus's own editorial board decides, on an ongoing basis, which sources meet its bar for inclusion, and which no longer do.
The two names researchers hear most often in this context are Scopus (Elsevier) and Web of Science (Clarivate). Both are large, independently curated citation databases; both are widely used as shorthand for "legitimate, quality-reviewed research"; and, despite frequent confusion, they are separate products, run by separate companies, with separate (and only partially overlapping) journal lists. More on that distinction below.
What Is a Scopus Journal, Exactly?
A Scopus journal is a journal that has an active, current listing in Scopus's official source database, not one that merely says so on its own website. Concretely, that means:
The journal applied (or was nominated) for Scopus coverage.
It passed Scopus's technical eligibility screen and full editorial review.
Scopus's CSAB approved it for ongoing inclusion.
It remains listed today. Indexing is a status that can be revoked, not a permanent badge.
A common misconception is that Scopus indexing is a single yes/no fact that never changes. In practice, Scopus publishes a public, regularly updated list of discontinued sources: journals removed after being accepted, typically for publication-integrity concerns, unusual citation behavior, or metrics manipulation (Elsevier, "Scopus content policy and selection"). That mechanism is exactly why checking a journal's current status (not an old screenshot, PDF, or the journal's own claim) is the only reliable approach, covered step by step later in this guide.
How Scopus Selects Journals for Indexing
Scopus's selectivity is one of the more concrete, verifiable facts in this space, and it's worth stating precisely because it's routinely understated by journals trying to look more common than they are.
Elsevier states it directly: every year, thousands of new titles are suggested for inclusion in Scopus, but only about 33% of those meet the rigorous technical criteria required to proceed to full review. Of the roughly 1,200 titles that clear that first screen, only about 50% are ultimately accepted by the independent CSAB (Elsevier, "Scopus content," July 2025). Put together, that's a funnel where roughly one in six initially-suggested titles ends up indexed.
Technical screening covers things like publication regularity, peer-review rigor, English-language abstract availability, and online accessibility. The second-stage CSAB review goes further, evaluating editorial quality, the international diversity of the editorial board and authorship, and citation-based impact. A journal that clears both stages has been vetted by people, not just an automated checklist. (For a concrete sense of what that editorial oversight looks like in practice, IJACSA, a Scopus Indexed Journal, publishes its full editorial board: the kind of named, checkable roster CSAB reviewers evaluate for international diversity and subject expertise.)
Scopus Journal Metrics: CiteScore, SJR, and SNIP Explained
Every Scopus journal carries three journal-level metrics, and they're frequently conflated because journals tend to cite whichever number looks best without explaining what it measures.
CiteScore is the most straightforward: it's citations received in a given year to documents published in the prior four years, divided by the number of those same documents. For example, a 2024 CiteScore counts citations made in 2024 to everything the journal published from 2021 through 2024, divided by how many articles, reviews, conference papers, book chapters, and data papers it published in that same four-year window (Elsevier/Scopus Support Center, "What is CiteScore?", updated June 3, 2025). Articles-in-press don't count until formally published.
Metric | What it measures | Best for |
|---|---|---|
CiteScore | Raw average citations per document over a rolling 4-year window | Comparing a journal's citation activity in absolute terms |
SJR (SCImago Journal Rank) | Prestige-weighted citations: a citation from a high-prestige journal counts more than one from a low-prestige journal (similar logic to Google's original PageRank) | Judging the quality of the sources citing a journal, not just the volume |
SNIP (Source Normalized Impact per Paper) | Field-normalized citation impact, adjusting for the fact that citation frequency varies enormously by discipline | Comparing journals across different fields fairly |
SJR was developed by SCImago and is explicitly designed around the idea that not all citations are equal: a citation from a widely-cited, high-prestige journal transfers more weight than one from an obscure, rarely-cited outlet (Elsevier, "Measuring a journal's impact"). SNIP solves a different problem: it corrects for the fact that, say, a mathematics paper and a molecular biology paper accumulate citations at very different natural rates, so a raw citation count would unfairly penalize journals in lower-citing fields. Comparing two journals' CiteScore alone, without checking their field, can be genuinely misleading; SNIP is the metric built specifically to correct for that.
None of these three metrics is "the" Scopus score. A journal citing only its highest number, without naming which metric it is, is a small but real transparency red flag in itself.
Scopus Journal vs. Web of Science Journal: What's the Difference?
These two labels get used almost interchangeably in casual conversation, and that's the single most common point of confusion for authors choosing where to publish. A Scopus journal and a Web of Science journal are not the same thing.
Scopus | Web of Science | |
|---|---|---|
Owner | Elsevier | Clarivate |
Core metric | CiteScore, SJR, SNIP | Journal Impact Factor (JIF), via Journal Citation Reports |
Coverage scope | Broader: 7,000+ publishers, 330+ disciplines | Traditionally narrower, more selective core collection |
Selection body | Content Selection & Advisory Board (CSAB) | Web of Science's own editorial selection process |
Journal overlap | Substantial but incomplete overlap with WoS | Substantial but incomplete overlap with Scopus |
Common use case | Citation tracking, journal comparison, author profiles (Scopus Author ID) | Impact Factor-based journal evaluation, especially in fields/countries where JIF is the historical standard |
A journal can be indexed in one, both, or neither. Being in Scopus says nothing definitive about Web of Science status, and vice versa. They run independent review processes with different criteria, which is precisely why a journal genuinely accepted by both has cleared two separate, independent bars rather than one. That's the basis for the "dual indexing" discussion further down this guide.
How to Verify a Journal Is Genuinely Scopus-Indexed
This is the single most useful thing to take from this guide, and it takes under five minutes:
Go to the official Scopus source list at scopus.com/sources. This tool is free and does not require a Scopus subscription to use.
Search by exact journal title or ISSN, not by publisher name, which can return unrelated sister publications.
Confirm the listing is current, not historical. The source list distinguishes actively-indexed titles from those on the discontinued list; a journal can legitimately appear in search results while no longer being actively indexed.
Cross-check the ISSN, not just the title. Predatory and imitator journals sometimes adopt near-identical names to legitimate indexed journals; matching the ISSN is the only reliable disambiguator.
Check the coverage years. Scopus lists the specific year range a title has been indexed for. A journal indexed "from 2023" was not covered before that, even if it existed earlier.
Ignore indexing badges/logos on the journal's own site. These images are trivial to copy and paste onto any website and carry no verification value on their own. Always confirm against the Scopus source list directly, not the journal's self-reported claim.
If a journal cannot be found on this list under its correct ISSN, it is not currently Scopus-indexed, regardless of what its homepage, submission emails, or marketing materials say.
Red Flags: Spotting False Claims
False or exaggerated indexing claims are common enough that they're a defining feature of predatory academic publishing. Watch for these specific patterns:
A logo instead of a link. Legitimate indexing claims should point directly to the journal's Scopus source page or be trivially verifiable there, not just display an image.
Vague or shifting metric claims ("high impact factor" with no number, or a number with no named source year).
Unusually fast peer review with no substantive feedback, paired with an indexing claim used as the main selling point in solicitation emails.
Journal name closely mimics a real indexed journal, differing by a word order, an added regional qualifier, or a near-identical acronym: a known predatory tactic that specifically exploits the fact that most authors check indexing by name recall rather than ISSN.
The journal appears on Scopus's discontinued sources list. This list exists because acceptance isn't a one-way door: a title can pass initial review and still be delisted later if Elsevier's ongoing quality monitoring turns up problems (Elsevier, "Scopus content policy and selection"), a status entirely different from, but easily confused with, a journal that was never indexed at all.
None of these signs alone is proof of a problem, but two or more together are a strong reason to verify directly on scopus.com/sources before submitting or citing.
Why Dual Indexing in Scopus and Web of Science Is Rare and Valuable
Because Scopus and Web of Science run independent selection processes with different criteria, a journal indexed in only one has cleared one editorial bar. A journal indexed in both has independently satisfied two separate review boards, at two separate organizations, evaluating different aspects of quality. That's a meaningfully stronger signal than either credential alone, and one that's genuinely uncommon among computer science journals specifically.
IJACSA (the International Journal of Advanced Computer Science and Applications, published by thesai.org) is a concrete, checkable example: it holds active dual indexing in both Scopus and Web of Science, with a current CiteScore of 3.4 and Journal Impact Factor of 1.1, both listed at the Q3 quartile as shown on its official indexing and metrics page, figures you can verify directly on Scopus and Clarivate's own databases rather than take on faith. That verifiability is the point of this whole guide: don't take our word for the dual-indexing claim any more than you'd take any other journal's. Check it yourself using the steps above.
Disclosure: The author of this post is Editor-in-Chief of IJACSA. We're using it as the example below precisely because its figures are independently checkable. Verify them yourself the same way you would for any other journal, using the steps in the previous section.
Why Publishing in a Scopus Journal Matters to Your Career
Beyond the abstract credibility question, publishing in a Scopus journal has practical, often binding consequences for researchers:
Promotion and tenure reviews at many universities explicitly weigh Scopus- or Web of Science-indexed publication counts, though exact policies vary significantly by institution and country (FAU Libraries, "Faculty, Promotion, Tenure, and Impact Factors"; UTSA Faculty Review guide).
National research-assessment frameworks in several countries formally require indexed publications: for example, India's UGC-CARE framework and China's research-evaluation policies both lean heavily on Scopus/Web of Science status as a quality proxy.
Grant applications frequently ask applicants to list indexed publications as evidence of research productivity and impact.
Discoverability and citation tracking: a paper published in a Scopus journal is automatically pulled into citation counts, author profiles (like a Scopus Author ID), and institutional research metrics, which unindexed publications simply are not.
Exact requirements vary enormously by institution, country, and field. There's no single universal percentage to cite here, and any guide claiming otherwise is oversimplifying. The safe generalization: indexed status is a recognized proxy for quality in enough review systems worldwide that verifying it before submission is rarely wasted effort.
Frequently Asked Questions
Is Scopus the same as Web of Science?
No. They are separate products from separate companies (Scopus from Elsevier, Web of Science from Clarivate) with different core metrics (CiteScore/SJR/SNIP vs. Journal Impact Factor), different selection boards, and overlapping but non-identical journal coverage. A journal can be indexed in one, both, or neither.
How long does Scopus indexing review take?
Elsevier does not publish a fixed universal timeline, since review depends on the CSAB's schedule and the completeness of a journal's application, but the process involves an initial technical screening followed by a separate substantive CSAB review, meaning it is a multi-stage process measured in months, not a same-day approval, regardless of what any journal's marketing suggests.
Can a journal lose its Scopus indexing?
Yes. Acceptance is not permanent. Elsevier's own content-policy documentation confirms Scopus reviews indexed titles on an ongoing basis and removes any that no longer meet its standards, publishing the result as a public discontinued-sources list (Elsevier, "Scopus content policy and selection"). This is exactly why checking a journal's current status directly on scopus.com/sources, rather than trusting an old claim, screenshot, or badge, is the only reliable verification method.
Is a high CiteScore always better than a lower one?
Not necessarily across different fields. CiteScore is a raw citation ratio and doesn't adjust for the fact that citation norms vary enormously by discipline. SNIP exists specifically to make fair cross-field comparisons: a lower CiteScore in a naturally low-citing field can represent stronger relative performance than a higher CiteScore in a heavily-citing one.
Does a journal being Scopus-indexed guarantee it isn't predatory?
It substantially reduces the risk, since indexed journals passed independent editorial review, but it isn't an absolute guarantee. That's exactly why Scopus maintains a discontinued-sources list for journals removed after the fact. Ongoing verification (checking current status, not a one-time historical fact) remains the more reliable practice than treating indexing as a permanent, unconditional stamp of approval.
Where can I check a journal's real Scopus status myself?
Directly at scopus.com/sources, free and without a subscription. Search by exact ISSN, confirm the listing is current (not on the discontinued list), and check the specific coverage years shown. Don't rely on logos, badges, or claims on the journal's own website.
Why do some journals only advertise "Scopus indexed" without naming a specific CiteScore, SJR, or SNIP value?
It can be a simple omission, but a journal that names only the fact of indexing, without a specific, named, sourced metric, makes it harder to independently assess its actual standing relative to other journals in the field. Cross-checking the exact figures directly on the journal's official Scopus source page closes that gap in under a minute.
Conclusion
The single most useful habit this guide can leave you with is simple: never take an indexing claim at face value. Check it yourself, directly on scopus.com/sources, by exact ISSN, every time. Being a genuine Scopus journal is a real, meaningful, but conditional status: one that thousands of journals apply for annually, a minority earn, and a smaller number occasionally lose.
If you're evaluating computer science journals specifically and want a verifiable example of what dual Scopus and Web of Science indexing looks like in practice, IJACSA's indexing and metrics page lists its current CiteScore, Impact Factor, and indexing status directly. It's worth a look as a reference point, not a pitch, for what to check on any journal you're considering. Authors weighing a submission can also review IJACSA's author guidelines directly.
