How To Check Impact Factor Of Journal: A Step-by-Step Guide For Researchers
The Journal Impact Factor measures the yearly average number of citations to recent articles published in a specific academic publication, serving as a primary metric for research evaluation. To check this metric accurately, researchers must utilize authorized citation databases like Clarivate's Journal Citation Reports while avoiding predatory publishers that display fake or misleading metrics.
Pre-Publication Research Assessment Checklist
Before submitting a manuscript to an academic publisher, validating the publication's official standing is critical to protect research integrity and prevent academic fraud. This evaluation phase ensures that citations count toward institutional tenure, funding requirements, and scholarly visibility.
- Essential Research Tools: Access to institutional subscriptions for Clarivate Analytics Journal Citation Reports, database credentials for Scopus, and official publisher profile pages.
- Prerequisite Knowledge: Understanding the difference between Clarivate's official Journal Impact Factor, Scopus CiteScore, and SCImago Journal Rank to avoid metric confusion.
- Resource Allocation: Zero financial cost if accessed via university network libraries; standard individual subscription fees apply for independent researchers. Time investment ranges from ten to fifteen minutes per journal verification.
Step-by-Step Workflow for Verifying Journal Metrics
Step 1: Access Authorized Bibliographic Databases
Begin the verification process by logging into your university library portal or institutional account that maintains an active subscription to Clarivate Analytics. Navigate directly to the Web of Science platform or the standalone Journal Citation Reports portal, as these are the sole originators of the official metric trademarked as the Journal Impact Factor. Avoid relying on third-party promotional banners on journal homepages, as predatory journals frequently fabricate these scores or misrepresent alternative metrics.
Pro-Tip: Always verify the ISSN (International Standard Serial Number) of the target publication. Journals often share remarkably similar titles, making the unique print or electronic ISSN the only foolproof identifier during database queries.
Step 2: Query the Target Publication Profile
Enter the exact journal title, abbreviation, or ISSN into the primary search bar of the Journal Citation Reports interface. Select the correct database edition, typically encompassing the Science Citation Index Expanded or the Social Sciences Citation Index, depending on your academic discipline. Once the journal profile page loads, examine the header data to confirm that you are viewing the correct volume year and category rankings.
Step 3: Extract and Calculate the Metric Components
Review the underlying data table provided in the journal profile, which displays the total number of citable items published over the preceding two years alongside the total number of citations received by those items in the current year. The Journal Impact Factor is derived mathematically by dividing the number of current-year citations by the total citable items published in the two previous years. Verify the quartile ranking within the specific subject category to understand the journal's relative standing among its peers.
Warning: Be cautious of the difference between the traditional Journal Impact Factor and the newer Journal Citation Indicator, which normalizes citation impact across different subject fields to account for varying citation cultures.

Comparison of Scholarly Metric Platforms
| Metric Name | Owning Organization | Calculation Window | Primary Database Source | Best Use Case |
|---|---|---|---|---|
| Journal Impact Factor | Clarivate Analytics | 2 Years | Web of Science | Institutional evaluation and traditional tenure review |
| CiteScore | Elsevier | 4 Years | Scopus | Broad disciplinary assessment and comprehensive publisher coverage |
| SCImago Journal Rank | Scopus / SCImago | 3 Years | Scopus | Evaluating journal prestige weighted by the citation network |
| Source Normalized Impact per Paper | Centre for Science and Technology Studies | 3 Years | Scopus | Cross-field comparison normalizing citation frequency differences |
Common Verification Failures and Field Fixes
- Root Cause: Finding a dramatically inflated impact factor advertised on a journal homepage that does not appear in official database queries.
- Actionable Fix: Cross-reference the title against the official Master Journal List and verify whether the publisher utilizes misleading metrics such as the Global Impact Factor or Universal Impact Factor.
- Root Cause: Inability to access the Journal Citation Reports portal due to missing institutional credentials.
- Actionable Fix: Authenticate through your university library proxy server, or utilize open-access alternative databases such as the SCImago Journal Rank platform to evaluate journal quartile rankings safely.
- Root Cause: Confusion arising from dual-format journals possessing both print and electronic ISSNs.
- Actionable Fix: Search exclusively by the journal title string or utilize the primary ISSN listed on the publisher's copyright statement page rather than promotional headers.
Frequently Asked Questions
What is a good Journal Impact Factor?
A strong metric varies entirely by academic discipline, as fields with high publication and citation volumes naturally exhibit higher scores. For instance, multidisciplinary science journals often reach scores above ten, whereas specialized humanities or localized engineering fields may consider a score above one to be exceptional.
Is the Journal Impact Factor the same as Scopus CiteScore?
No, these metrics are produced by different indexing corporations and utilize different calculation windows. While the traditional impact factor measures citations over a two-year window using Web of Science data, CiteScore measures a four-year window using Scopus data.
Can open-access journals have an impact factor?
Yes, fully open-access journals that meet rigorous editorial and peer-review standards are indexed in Web of Science and receive official metrics. Researchers should confirm indexing status directly within the database rather than trusting unverified claims on open-access landing pages.
Why do some legitimate journals lose their impact factor?
Journals can experience metric suppression if Clarivate detects anomalous citation patterns, excessive self-citation, or systematic manipulation of the peer-review process. Monitoring annual update reports ensures your target publication maintains its standing.
Streamline your academic publishing strategy by verifying journal metrics through official databases before manuscript submission.
