If you\u2019ve ever Googled \u201chow to increase your h-index,\u201d you\u2019ve most likely come across the same advice over and over again: \u201cpublish more,\u201d \u201cchoose popular topics,\u201d \u201ccite yourself.\u201d Some of this is true. But only some of it.<\/p>

At the same time, there are methods that researchers consider effective, but which in reality either yield no results or even damage one\u2019s reputation. It is especially important for those who publish in Scopus or Web of Science to understand this\u2014after all, that is where your actual Hirsch index is calculated. Regarding, How do journals get into Scopus, and what are the criteria?<\/a>, as we've mentioned before.<\/p>

This article contains only facts backed by research. No fluff, no nonsense. 7 real factors + 3 myths that need to be debunked once and for all.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

1. Co-authorship of highly cited articles<\/strong><\/p>

Impact:<\/strong> HIGH<\/p>

The Hirsch index is allocated equally among all co-authors of an article. If an article has received 80 citations, each of the five authors receives all 80 of those citations toward their h-index. In full.
But what\u2019s more important is this: each co-author brings their own citation network\u2014colleagues from their university, country, and field. This multiplies the visibility of the work.<\/p>

Perneger\u2019s study (2023, *Research Integrity and Peer Review*)\u2014an analysis of 18,231 leading researchers\u2014shows that an author\u2019s \u201cmid-list\u201d status correlates with the h-index at a level of r = 0.64. In contrast, the correlation for sole authors is negative (r = \u22120.06).<\/p>

Conclusion:<\/strong> Strategic collaboration on high-quality projects is one of the most powerful drivers of growth in the Hirsch index.<\/p>

\u00a0<\/p>

2. Open Access<\/strong><\/p>

Impact:<\/strong> MEDIUM\u2013HIGH<\/p>

An open-access article is available to any researcher, regardless of whether their university has a subscription. This broadens the pool of potential readers\u2014and those who might cite you.<\/p>

The meta-analysis by Langham-Putrow et al. (2021, PLoS ONE) included 134 studies: 64 of them (47.8%) confirmed the citation advantage of open access. Open-access articles are cited 18% more than the average; paywall articles are cited 10% less.<\/p>

The trend is intensifying: according to Frontiers Policy Labs, the proportion of studies confirming the advantages of OA has increased from 66% (2001\u20132015) to 82% (2016\u20132021).<\/p>

\u00a0<\/p>

3. Quartiles of the journal (Q1 vs. Q4)<\/strong><\/p>

Impact:<\/strong> HIGH<\/p>

Q1 journals have a larger readership, are better indexed in Scopus and Web of Science, and are cited more frequently on a consistent basis.<\/p>

An important nuance:<\/strong> Citations are counted toward the Hirsch index only if they are indexed in Scopus or WoS. An article published in a non-indexed journal is \u201cinvisible\u201d in terms of citations.<\/p>

For more information on, how Scopus evaluates and accepts journals,<\/a> And to find out why quartiles are so important for your citation count, read our separate article.<\/p>

A study by radiology departments (ScienceDirect, 2016): Each unit increase in the faculty\u2019s median h-index raises the department\u2019s h-index by 15.7 points\u2014and this is primarily due to publications in journals with high impact factors.<\/p>

\u00a0<\/p>

4. Self-citation\u2014a minimal but real effect<\/strong><\/p>

Impact:<\/strong> LOW (at the start of his career\u2014MEDIUM)<\/p>

Self-citation can help an article exceed the citation threshold required for inclusion in the h-core. But this applies only to authors with a low h-index.<\/p>

Mayo Clinic (Academic Radiology, 2012) \u2014 487 researchers: after accounting for self-citations, the h-index rose only from 13.7 to 14.0. For the 77% authors, the h-index did not change at all.<\/p>

For an experienced researcher, self-citation has almost no effect on the outcome. For a beginner, it may slightly accelerate initial growth.<\/p>

\u00a0<\/p>

5. Interdisciplinary Research<\/strong><\/p>

Impact:<\/strong> AVERAGE (depends on the field)<\/p>

Interdisciplinary works can be cited by researchers from various fields, which broadens their audience. But there\u2019s a catch: if the range of topics is too broad or the distribution across fields is too even, it reduces their citability.<\/p>

Yegros-Yegros et al. (2015, PLoS ONE): The diversity of fields in the reference list correlates positively and significantly with citations. However, excessive disparity among fields has a negative effect.<\/p>

Practical note:<\/strong> Interdisciplinary works often have a delayed citation cycle\u2014the effect becomes apparent after several years, rather than within the standard 2\u20133-year window.<\/p>

\u00a0<\/p>

6. Academic Age \u2014 Time in Science<\/strong><\/p>

Impact:<\/strong> HIGH (structural)<\/p>

The Hirsch index can only go up\u2014it never goes down. Hirsch (2005) described it this way: h increases approximately linearly with the number of years of active research.<\/p>

A study of approximately 1,400 Italian physicists (Rossi et al., 2013): the average h-index\/academic age ratio \u2248 3.8. Comparing the h-indices of researchers at different career stages without normalization is methodologically incorrect.<\/p>

A researcher with h = 20 after 10 years of work may objectively outperform a colleague with h = 28 after 30 years. It is important to understand this when evaluating yourself.<\/p>

\u00a0<\/p>

7. Popularity of the topic and alignment with trends<\/strong><\/p>

Impact:<\/strong> HIGH (structural)<\/p>

If your topic is at the center of active scientific discourse (AI in medicine, climatology, mRNA technologies), your work will be cited more often simply because of the larger audience. Current trends in scientific publications in 2026 confirm that choosing a topic is a strategic decision.<\/p>

Hirsch (2005) himself cautioned that the Hirsch index should only be used to compare researchers within the same field\u2014due to fundamental differences in citation norms.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

Myth 1: Publish widely and frequently\u2014in low-quality journals<\/strong><\/p>

Why do they think that?<\/strong> More publications = a better chance of getting citations.<\/p>

Why it doesn't work:<\/strong><\/p>

\u2022 Journals with a low impact factor have a small readership and are rarely cited;
\u2022 The h-index is mathematically independent of the number of articles with 0\u20132 citations. A hundred such publications will not raise the h-index by even a single unit;
\u2022 According to Seglen (1992): in most journals, ~85% articles are cited less frequently than the journal\u2019s own average.<\/p>

A mathematical property of the h-index: a concentration of high-quality publications in a few highly cited works is always better than spreading them out across dozens of weak ones.<\/p>

\u00a0<\/p>

Myth 2. Publishing in predatory \u201cindexed\u201d journals<\/strong><\/p>

Why do they think that?<\/strong> If a journal states that it is indexed in Scopus \/ WoS, that means citations will be counted.<\/p>

Why it doesn't work:<\/strong><\/p>

\u2022 Scopus and WoS count only citations from journals that are actually verified in their databases.
\u2022 Following a comprehensive review in 2017, Elsevier removed all journals on Beall\u2019s List from Scopus.
\u2022 Analysis of 7 predatory journals (MIT \/ Scholarly Kitchen, 2019): Citations virtually ceased after the expos\u00e9.<\/p>

About that, How Ukrainian Researchers Are Being Deceived by Journals That Are Supposedly Indexed in Scopus<\/a>, \u2014 we discuss this in detail in a separate article.
JMLA (2025): Of the 3,671 articles published in 26 predatory medical journals, only 31.4% were cited at least once in the verified WoS literature.<\/p>

\u00a0<\/p>

Myth 3. Citation rings and forced citations<\/strong><\/p>

Why do they think that?<\/strong> Cross-citation among a group of colleagues quickly boosts the metrics.<\/p>

Why it doesn't work and what the risks are:<\/strong><\/p>

\u2022 The Scopus and WoS algorithms identify anomalous citation clusters.
\u2022 If detected\u2014retraction of all related articles and a record in the permanent scientific reputation database.
\u2022 COPE (Committee on Publication Ethics) 2026: If a single article is found to be part of a ring, all articles in the network are subject to retraction.<\/p>

Case Study: SAGE \/ Journal of Vibration and Control (2014) \u2014 60 retractions following the discovery of a citation ring. The editor\u2019s career was ruined.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

The Hirsch Index is neither a matter of chance nor a lottery. It is a measurable result of systematic decisions: the right journal, the right co-authors, and the right topic at the right time.<\/p>

Three factors that you can control\u2014where you publish, with whom you publish, and how in-demand your topic is\u2014produce a real, predictable effect.<\/p>

Workarounds\u2014predatory journals, citation rings, and scattering articles across dozens of low-quality publications\u2014either yield no results or ruin one\u2019s reputation. These are no longer mere opinions, but documented facts from peer-reviewed studies.<\/p>

Increasing your Hirsch index is like running a marathon with a strategy. But if your strategy is right, the result is predictable.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
