How to Check if an Article Is Peer-Reviewed in Google Scholar


Google Scholar is one of the most widely used tools for academic research. It provides quick access to millions of journal articles, theses, books, and conference papers. However, Google Scholar does not label which articles are peer-reviewed. This creates confusion for students, researchers, and professionals who want to make sure they are using credible, scholarly sources.

This guide explains practical steps you can use to determine whether an article found on Google Scholar is peer-reviewed. It also covers how to cross-check journal credibility, use publisher databases, and identify reliable academic content.


Understanding What Peer-Reviewed Means

A peer-reviewed article is one that has been evaluated by experts in the same field before publication. This process ensures that the research is accurate, original, and meets academic standards.

Peer review usually involves:

  1. Submission of the manuscript to a journal.

  2. Review by two or more independent experts.

  3. Feedback and revisions from the author.

  4. Final approval by the journal editor.

Peer review protects against poor-quality or biased research. When you cite peer-reviewed work, you build credibility and show that your arguments are supported by evidence verified by professionals.


Why Google Scholar Does Not Mark Peer-Reviewed Articles

Google Scholar indexes a wide range of content, including journal articles, preprints, dissertations, conference papers, and even reports hosted on university websites. Because of this diversity, it does not display a specific badge or tag showing whether a source is peer-reviewed.

Instead, it relies on publishers and databases to provide metadata. Some of these publishers include peer-reviewed journals, while others do not. The researcher must verify this manually.


Step-by-Step: How to Check if an Article Is Peer-Reviewed on Google Scholar

Step 1: Search for the Article

Go to scholar.google.com and enter the title of the article. Use quotation marks around the title to get an exact match.

Example:
“Effects of Climate Change on Crop Production in Sub-Saharan Africa.”

This helps you locate the correct paper and its full citation.


Step 2: Identify the Journal or Publication Source

Look at the line beneath the article title in Google Scholar search results. You will see the journal name or the platform where it was published.

Example:
Journal of Environmental Science and Policy, 2023.

If you see a university repository, conference name, or working paper series instead of a journal, that source may not be peer-reviewed.


Step 3: Visit the Journal’s Official Website

Once you have the journal name, open a new tab and search for it on Google. Use a query like:

“Journal of Environmental Science and Policy peer review policy.”

Every reputable academic journal has a page that explains its peer review process, editorial board, and publication standards. If the site confirms that all articles undergo peer review before publication, you can trust that your selected paper is peer-reviewed.


Step 4: Verify the Journal’s Status in Reputable Databases

To ensure the journal is recognized, check if it is indexed in trusted databases. Peer-reviewed journals are usually listed in these platforms:

  • Scopus (Elsevier)

  • Web of Science (Clarivate Analytics)

  • PubMed (for health and medical sciences)

  • Directory of Open Access Journals (DOAJ)

  • Ulrichsweb Global Serials Directory

If the journal appears in one or more of these indexes, it is peer-reviewed or scholarly.

Example:
If you search Ulrichsweb for “African Journal of Public Health,” the entry will show whether it is “refereed.” Refereed means peer-reviewed.

Step 5: Check the Publisher’s Reputation

Publishers play a major role in maintaining quality standards. Trusted publishers known for peer-reviewed journals include:

  • Elsevier

  • Springer Nature

  • Taylor & Francis

  • Wiley

  • SAGE Publications

  • Oxford University Press

  • Cambridge University Press

If your article is published by one of these, it is likely peer-reviewed. Avoid journals from publishers with no clear peer-review process or those listed on predatory journal warnings, such as Beall’s List of Predatory Journals.


Step 6: Review the Article Structure and References

Peer-reviewed papers usually follow a formal academic format. Check if the article includes these sections:

  • Abstract

  • Introduction

  • Methodology

  • Results or Findings

  • Discussion

  • References

Each section should use formal academic language and include citations to previous studies. Articles without references or with poor structure may not have gone through peer review.


Step 7: Look for a DOI (Digital Object Identifier)

Most peer-reviewed journals assign a DOI to their published articles. It is a unique digital code that allows permanent identification and easy citation.

Example: https://doi.org/10.1016/j.jenvsci.2023.04.008

If your article has a DOI and is hosted by a recognized publisher, it is a strong sign that it was peer-reviewed.


Additional Tips for Confirming Peer Review

1. Use Google Scholar Metrics

Google Scholar provides a Metrics section where you can explore top journals in different subject categories. Journals listed in Google Scholar Metrics are usually peer-reviewed and ranked by their h-index.

To access it:

  • Go to Google Scholar Metrics.

  • Browse by category (for example, “Public Health” or “Computer Science”).

  • Look for the journal name from your article.

If it appears in these rankings, it follows recognized peer-review standards.

2. Use University Library Resources

Most universities provide access to journal databases that label whether articles are peer-reviewed. You can search the same article title in your university’s online library to confirm.

Examples of academic databases that mark peer-reviewed content:

  • EBSCOhost

  • ProQuest

  • ScienceDirect

  • JSTOR

If your institution subscribes to these platforms, use their filters such as “Peer-Reviewed Journals” or “Scholarly Articles Only.”

3. Contact the Author or Editor

If the journal or publisher information is unclear, you can email the article author or the journal editor. A short message asking whether the paper was peer-reviewed before publication is enough. Scholars often respond and provide details.




Common Misconceptions About Peer Review and Google Scholar

Myth 1: Everything on Google Scholar is peer-reviewed.
False. Google Scholar indexes academic-looking content, including preprints, theses, and working papers, many of which are not peer-reviewed.

Myth 2: Free-access articles are not peer-reviewed.
False. Many open-access journals are fully peer-reviewed. Examples include PLOS ONE and BMC Public Health, both indexed in PubMed and DOAJ.

Myth 3: Only journals with impact factors are peer-reviewed.
Not true. While many high-impact journals are peer-reviewed, some quality journals in niche fields may not have an impact factor but still conduct peer review.


Practical Example: Checking Peer Review Status

Suppose you find an article titled “Artificial Intelligence in Healthcare Delivery in Africa” on Google Scholar.

  1. You open the result and see it was published in the African Journal of Health Technology.

  2. You search the journal online and find its homepage.

  3. The “About” section explains the journal uses a double-blind peer review process.

  4. You check DOAJ and confirm the journal is listed as peer-reviewed.

  5. The article includes a DOI and formal sections (Abstract, Methodology, Discussion).

This confirms that the article is peer-reviewed and credible for academic use.


Red Flags That an Article May Not Be Peer-Reviewed

  • The journal has no official website or contact information.

  • The publisher charges submission fees but does not explain its peer-review process.

  • The article has grammatical errors or lacks citations.

  • The research claims unrealistic results or lacks a clear methodology.

  • The paper is published on a personal blog or institutional repository without peer review confirmation.

If you notice any of these warning signs, avoid using the source for academic writing or research projects.


Why Peer Review Still Matters

Using peer-reviewed sources strengthens your academic work in several ways:

  • It ensures your references come from credible research.

  • It builds trust in your findings and analysis.

  • It helps prevent misinformation and low-quality scholarship.

Whether you are writing a research paper, thesis, or policy brief, confirming peer review status should be a key part of your research process.


Summary Checklist

Before citing an article from Google Scholar, confirm these five points:

  1. Identify the journal name.

  2. Check the journal’s peer-review policy on its official site.

  3. Verify its indexing in Scopus, Web of Science, or DOAJ.

  4. Look for a DOI and academic article structure.

  5. Review publisher reputation and avoid predatory journals.

If all five boxes are checked, the article is likely peer-reviewed and suitable for academic use.


Final Thoughts

Google Scholar is a valuable starting point for research, but it does not automatically verify the quality or review status of articles. As a researcher or student, you must take extra steps to confirm whether an article is peer-reviewed.

By checking the journal’s official website, verifying its presence in reputable databases, and understanding basic scholarly publishing standards, you can ensure your references are credible and academically sound.

This approach improves the quality of your assignments, reports, or research papers and helps maintain academic integrity in your work.
