In today's scientific environment, where competition for recognition and citations is extremely high, SEO optimisation of scientific articles is becoming an important tool for researchers. It not only increases the visibility of publications in the digital environment, but can also have a positive impact on the Hirsch index, a key indicator of scientific productivity. In this article, we will look at what SEO optimisation is, how it works in the context of scientific publications, and how it contributes to increasing the Hirsch index.

What is SEO optimisation?
SEO optimisation is a set of measures aimed at improving the visibility of content in search engine results, such as Google and Google Scholar, or specialised databases (Scopus or Web of Science).
In the context of scientific articles, SEO optimisation involves using strategies that help articles appear higher in search results, making them more accessible to researchers, students, and other users.
The main elements of SEO optimisation for scientific articles include:
- Keywords: the use of relevant and popular terms that correspond to the topic of the article and the queries of the target audience.
- Metadata: clear formatting of titles, abstracts, and keywords to facilitate indexing by search engines.
- Quality content: creating structured and readable texts that meet academic writing standards.
- Links: including links to authoritative sources and ensuring backlinks to the article from other resources.
- Technical optimisation: ensuring correct formatting of the article (e.g. in PDF or HTML) for fast loading and indexing.
How does SEO optimisation helps to increase the Hirsch index?
At first glance, it may seem that there is no connection between SEO optimisation of an article and an increase in the Hirsch index. However, such activities contribute to an increase in the citation rate of scientific articles, which is a key factor in the growth of the index. Below, we will look at the aspects that make this happen.
Improving the visibility of articles in search engines
An SEO-optimised article is more likely to appear at the top of search results, for example, in Google Scholar or other academic platforms. This allows researchers from around the world to find the article more quickly, which increases the likelihood of it being cited.
The use of relevant keywords in the title, abstract, and text of the article plays a key role in this process, as they ensure that the article matches search queries.
Increased accessibility to an international audience
Another advantage of publication optimisation is an increase in the number of potential readers. SEO helps articles reach a wider audience, including researchers from different countries and disciplines. For example, translating the abstract into several languages or using universal scientific terms can attract the attention of foreign scientists, which in turn has a positive effect on the citation rate.
Improving metadata quality and citation rates
SEO involves creating clear and complete metadata (title, authors, keywords), which facilitates the automatic detection of articles by bibliometric systems. It also promotes accurate citation, which is important for calculating the h-index.
For example, a high-quality abstract with keywords increases the likelihood that an article will be included in reviews or bibliographies.
Attracting backlinks
A backlink is a hyperlink on a website or resource that leads to another website, page, or document, such as a scientific article. In the context of scientific publications, a backlink usually refers to your article or research from another source, such as a website, blog, repository, social network, or other scientific work.
This way, because your article will be mentioned on various platforms, the likelihood that your work will be cited by other scientists increases.
Supporting long-term relevance
SEO optimisation ensures that an article remains visible even years after publication. This is especially important for researchers, as the Hirsch index takes into account citations over a long period of time.
SEO optimisation of scientific articles is not only a tool for improving their visibility in search engines, but also an effective way to increase citations, which directly affects a researcher's Hirsch index.
