Webometrics Editions Explained: January vs July and How to Compare
Webometrics publishes two editions each year: the January edition is the first and the July edition is the second. The current edition is July 2026, labelled "2nd Edition – Final" on the ranking pages. Because a university can appear in both editions, the practical question for readers is how to compare a result across editions without mistaking a change in the data, or in the surrounding field of institutions, for a change in an institution's own web presence. Every university profile page on Webometrics.org also carries a Historical Ranking chart that shows an institution's results edition by edition. This article explains the edition cycle, how to read the edition label, how to use the edition history on a university page, and how to compare results responsibly.
Webometrics is a UNIRANKS project dedicated to the development and application of webometric university evaluation and research. Webometrics.org is the project's dedicated public website and publication platform. The indicators and their definitions are set out on the official Webometrics methodology page, which is the authoritative reference for anything described below.
What is a Webometrics edition?
An edition is one complete, dated release of the Webometrics results. Each edition presents institutions on the ranking pages with a World Rank and three indicator ranks: Impact Rank, Openness Rank and Excellence Rank. The three indicators are defined on the methodology page as follows: Impact concerns institutional visibility, authority and reach across the digital ecosystem; Openness concerns how effectively institutions make knowledge and resources publicly available and discoverable, including repositories and open-access materials; Excellence concerns the quality of scholarly and technical digital presence.
Two editions are published each year. The January edition is the first edition of the year and the July edition is the second. Webometrics does not tie readers to a fixed publication day, so the reliable way to know which edition you are looking at is to read the label on the page, not to infer it from the calendar.
How to read the edition label
The Webometrics methodology page states the current edition ("Current Edition: July 2026"). The world ranking, regional pages such as Asia and country pages such as Indonesia carry the label "July 2026 — 2nd Edition – Final". Read together, the label identifies three things: the month of the edition (July 2026), its position in the annual cycle (the 2nd edition of 2026) and its status (Final).
The label is a statement about the release being displayed. It is not a score, and it does not say anything about an individual institution. A reader who cites a position should always cite the edition label alongside it, for example "ranked Nth in the July 2026 Webometrics edition", because a position without an edition is ambiguous once a newer edition is published.
| Element on the ranking page | What it tells you | What it does not tell you |
|---|---|---|
| Edition month and year (July 2026) | Which release the figures belong to | When data for individual institutions were collected |
| Edition number (2nd Edition) | Whether it is the January (1st) or July (2nd) release of the year | How large the changes since the previous edition are |
| Status label (Final) | The status the ranking page assigns to this edition | Any rule beyond what the page itself states |
| World Rank and indicator ranks | An institution's position in this edition on each measure | The reason for any movement since an earlier edition |
The edition history on each university page
Each university profile page on Webometrics.org includes a chart titled "Historical Ranking". The chart plots four lines for the institution: World Rank, Impact Rank, Openness Rank and Excellence Rank. The horizontal axis lists the editions shown for that institution, labelled by year, with July editions marked "july" (for example "2025 - july" and "2026 - july"). The vertical axis shows rank position, so a line that moves upward represents a lower position (a larger rank number) and a line that moves downward represents a higher position.
The chart makes the points above visible at a glance. The four lines do not have to move together. On the Historical Ranking chart of Universidad Nacional Autónoma de México, for example, the World Rank line and the Openness Rank line follow clearly different paths across the editions shown, and in the most recent edition on the chart they move in opposite directions: the World Rank line moves down (a higher world position) while the Openness Rank line moves sharply up (a lower Openness position). Neither line alone explains the other. The example is an observation about how the chart reads, not a judgement about the institution or an explanation of the change.
Reading the chart is the quickest way to apply the comparison steps below, because it places every available edition for one institution on a single axis and separates the overall World Rank from the three indicator ranks.
Why positions move between editions
A rank is relative: it states where an institution sits among all institutions listed in that edition. A position can therefore change even when an institution's own web presence is unchanged, because other institutions have moved above or below it. Positions can also change when an institution's visibility, openness or scholarly presence has changed, and when the methodology is refined; readers should consult the methodology page for the current definitions.
Independent research on university rankings shows why this distinction matters. Sorz and colleagues (2015, PeerJ) examined year-to-year changes in two global rankings and found that mean fluctuation rose from under 10% among the 50 highest-ranked universities to as much as 60% in the lowest-ranked group they studied. They concluded that such fluctuations most likely do not correspond to academic performance. Selten and colleagues (2020, Quantitative Science Studies) analysed three global rankings over time and found high rank correlations between consecutive years for the top 100 (Spearman 0.89 to 1.0), while noting that changes in data sources and in the number of institutions ranked may be connected to shifts in results. Both studies concern other ranking systems and say nothing specific about Webometrics; they are cited here for the general principle that rank movement has several possible causes and should not be read as performance change by default.
The Berlin Principles on Ranking of Higher Education Institutions, adopted by the International Ranking Expert Group in 2006, make a related point from the producer's side: Principle 6 asks rankings to be transparent about the methodology used. For readers, the corollary is simple: before interpreting a change, check what the published methodology says for the editions being compared.
How to compare results across editions
The following steps are a Webometrics reading guide for anyone comparing an institution, a country or a region across editions.
- Name both editions. Record the exact label for each, for example "July 2026 (2nd Edition)" and the January edition it is compared with. On a university page, use the edition labels on the Historical Ranking chart.
- Compare the same measure. Compare World Rank with World Rank, and Impact Rank with Impact Rank. Do not compare a world position with a national or regional one.
- Prefer indicator ranks over the overall rank when asking why. If an institution's World Rank changed, the three indicator ranks, shown as separate lines on the Historical Ranking chart, show whether the movement appears in Impact, Openness, Excellence or several of them. This describes where the change shows up; it does not explain why it happened.
- Look at the neighbourhood, not only the number. A shift of a few places among institutions that are closely bunched is a different thing from a shift across a wide gap. Compare against peers in the same country or region.
- Check the methodology page. Check the current definitions, and any refinement Webometrics has documented, before attributing a change to the institution.
- Allow for a single edition being a snapshot. A single pair of editions is a limited basis for identifying a trend; several editions give a clearer picture.
Comparing the two editions of the same year (January against July) and comparing the same edition across years (July 2026 against the following July) answer different questions. The first looks at change over a short interval; the second compares like with like in the annual cycle. Which is appropriate depends on what the reader wants to know, and the label makes either comparison transparent.
Implications for universities
Web, communications, library and research-office teams that report their Webometrics position internally or externally can make those reports more useful in three ways. They can cite the edition label with every position. They can report the three indicator ranks as well as the World Rank, so that colleagues can see which area the movement relates to, and they can share the Historical Ranking chart from the institution's own page rather than a single figure. And they can record the date they accessed the page, so that the figure remains traceable when the next edition replaces the current one. Webometrics does not promise that any particular action will change an institution's position in a future edition.
Readers who want to understand what the results are and are not designed to say can also read Is the WEBOMETRICS Ranking Reliable?

Practitioners interested in how an institution's indicators can be followed over several years may also find From Metrics to Action useful as a longitudinal case study.
Limitations
This article describes the edition cycle, the labels displayed on Webometrics pages and the Historical Ranking chart as they appear on the site. The chart shows the editions available for each institution, and the number of editions shown can differ between institutions. This article does not set out dates of future releases, does not describe the contents of earlier editions, and does not define rules for the "Final" status beyond what the ranking pages show. The two independent studies cited examine other ranking systems; their findings are used as general context and not as evidence about Webometrics results. The supporting UNIRANKS Web Growth Intelligence (GI) and UNIRANKS Open Index (OI) infrastructure is described on the methodology page and is outside the scope of this article.
Frequently asked questions
How many editions does Webometrics publish each year?
Two. The January edition is the first and the July edition is the second.
Which edition is current?
The current edition is July 2026, labelled "2nd Edition – Final" on the ranking pages. Check the label on the page you are reading, because it changes when a new edition is published.
Can I compare a January result with a July result?
Yes, provided you name both editions and compare the same measure. Treat the difference as a change between two snapshots, not as proof of why an institution moved.
Where can I see how a university has changed across editions?
On the university's own profile page, in the Historical Ranking chart. It plots the World Rank, Impact Rank, Openness Rank and Excellence Rank for each edition shown for that institution.
Why did an institution's position change between editions?
A position is relative to all other institutions in the same edition, so it can move because of changes in the institution, changes in other institutions, or methodology refinements. The indicator ranks show where the movement appears; they do not by themselves establish the cause.
Where do I find the official definitions?
On the official Webometrics methodology page, and on the current Webometrics ranking results.
