Scopus quartiles and Web of Science indexing, shown directly on Google Scholar.
What you see on every article
Emotion and its relation to cognition from Vygotsky's perspective
Google Scholar tells you where a paper was published, but not whether that venue is any good. This extension adds that missing layer.
On every search result and every publication in an author profile, it shows the journal's Scopus quartile (Q1–Q4, from SCImago) and which Web of Science index carries it — SCIE, SSCI, AHCI or ESCI — along with the SJR score and open-access status. Above the list, a summary bar counts every index found.

The summary bar lists only the indexes actually present, each with a count.
Every chip is a + button.
The total is a union, not a sum: Q1 (30) plus ESCI (14) gives 38, not 44, because six publications are in both and each is counted once.
These metrics are useful, and routinely over-read. Here is what each one actually measures.
| Metric | What it measures |
|---|---|
| SJR | SCImago Journal Rank. Average prestige-weighted citations per document over three years. A citation from a highly cited journal counts for more than one from a rarely cited journal. There is no universal “good” value — 1.5 is strong in education and unremarkable in molecular biology. |
| Q1–Q4 | Journals in a subject category ranked by SJR and split into four equal groups. Q1 is the top 25%. Because quartiles are relative to a field, they compare across disciplines better than raw scores do. |
| SCIE SSCI AHCI |
The three selective indexes of the Web of Science Core Collection — sciences, social sciences, and arts & humanities. They are peers, not a ranking: which one a journal sits in reflects its subject area, not its standing, and a journal can appear in two. In many institutions, SSCI is the threshold that counts for hiring and promotion. |
| ESCI | Emerging Sources Citation Index — a separate, newer tier for journals that meet basic quality criteria but not yet the Core Collection standard. ESCI journals get no Journal Impact Factor. Many are perfectly respectable; it is simply not equivalent to SSCI or SCIE. |
| Journal h-index |
On hover. The largest h where the journal has h articles each cited at least h times. It accumulates with age, so old journals out-score young ones regardless of current quality. |
| Cites/doc (2 years) |
On hover. The closest figure here to the familiar Journal Impact Factor, but computed from Scopus rather than Web of Science — so it will not equal a JIF quoted elsewhere. |
| Coverage | On hover. The years Scopus has indexed the journal. A span that ended a few years ago means the journal was discontinued from Scopus, which is a meaningful warning sign. |
| OA | The journal is fully open access according to SCImago. This describes the journal's publishing model, not whether one article happens to be free to read somewhere. |
Written with graduate students and early-career researchers in mind, because these are the decisions where a misread metric costs the most.
scimagojr.com and mjl.clarivate.com before anything that goes in a CV or grant form.Sometimes no badge appears. That is deliberate, and worth knowing about.
On search pages Google Scholar often shortens a long journal name to something like International Journal of …. Hundreds of journals begin that way, so the name no longer identifies one. Rather than guess and risk showing you the wrong quartile, the extension shows nothing. Open the article to see the full journal name, or check the same paper on the author's profile, where names are not shortened.
A blank can also simply mean the journal is in neither Scopus nor Web of Science. And where a name is matched from an abbreviation or a shortened form, the badge is drawn with a dashed outline — a reminder to confirm it before relying on it.
You can loosen or tighten this behaviour in the extension's settings.
Nothing is collected and nothing is sent anywhere. The extension reads the journal name shown under a result, looks it up in the list of journals stored inside it, and draws a badge. That is all it does.
It saves two things on your own computer: your display preferences, and the journal names it has already looked up so that repeat visits are instant. Neither includes article titles, authors, searches or web addresses, and both can be cleared from the extension at any time.
It runs only on Google Scholar pages and asks for no access to any other site, so it cannot read anything else you browse. There is no analytics, no tracking and no advertising.
Quartiles, SJR scores, subject categories and open-access status come from the SCImago Journal Rank dataset, derived from Scopus and covering more than 32,000 journals. Index membership — SCIE, SSCI, AHCI and ESCI — comes from Clarivate's Master Journal List.
Both are annual snapshots, so a paper is shown with its journal's
current standing rather than its standing at the time of publication.
Indexing changes through the year, so for anything consequential — a
submission, a promotion file, a funding form — confirm on
scimagojr.com and mjl.clarivate.com.
