A publication in a scientific journal can be considered successful only if it contributes to increasing the author’s h-index. However, it is important to understand that not every article automatically has a positive impact on this indicator. Whether a paper affects the h-index largely depends on how it is recognised and indexed by a particular database. For this reason, profiles in Scopus, Web of Science, and Google Scholar have become an important tool for building a scientific career. Below, we will examine how exactly these profiles influence the h-index and whether it is possible to manage without them.
Briefly about the h-index
Before examining the role that database profiles play in increasing the h-index, it is necessary to understand the principle behind the calculation of this indicator.
The h-index reflects the relationship between the number of an author’s publications and the number of citations those publications receive. Its calculation principle can be described using the following formula:
h-index = h, where h represents the number of articles that have received at least h citations each.
For example, if a researcher has 10 publications and each of them has been cited at least 10 times, their h-index equals 10. In contrast, if an author has 100 publications but only 5 of them have received 5 or more citations, while all the others have 4 citations or fewer, the h-index will only equal 5.
In practice, the h-index depends not on the total number of published papers, but on a stable and sufficient level of citations across a certain body of work. Even if one of your papers has a very high citation rate, while dozens of others remain largely unnoticed by the scientific community, your indicator will barely increase.

What role do databases play in shaping the h-index?
The main feature that early-career researchers often overlook is that the h-index is not a single universal number. Each scientometric platform calculates it independently, relying only on the publications and citations indexed within its own database. This is why the same researcher may have significantly different h-index values in Scopus, Web of Science, and Google Scholar.
How do author profiles work on different platforms?
Each platform creates a separate identifier and author profile containing the researcher’s publications, citation metrics, and h-index.
- Scopus – Scopus Author ID (created automatically after the first publication in journals indexed in the Scopus database).
- Web of Science – ResearcherID (must be created manually after the first publication).
- Google Scholar – personal Google Scholar profile (created and configured manually).
At this point, it is important to understand the key difference between the data these platforms use when calculating the h-index.
Author profiles in Scopus and Web of Science include only publications that appear in journals, conference proceedings, or books indexed in the respective database. For example, if a journal is not indexed in Scopus, the article will not appear in your Scopus profile and will not affect your h-index in this system. The same principle applies to Web of Science.
As for Google Scholar, it indexes virtually everything it can find on the internet: journal articles, preprints in repositories (such as arXiv or bioRxiv), dissertations, books, book chapters, conference proceedings, and even some patents.
What can lead to an incorrect h-index calculation?
Simply publishing in indexed journals is not enough. If an author profile is not actively maintained, some publications and citations may be lost or remain uncounted. As a result, the h-index may increase much more slowly.
The most common problems include:
- Duplicate profiles. The system may create two or more profiles for the same author due to different variations in the spelling of the name (for example, Smith O. and Smith Otto). Publications and citations become divided between profiles, and none of them reflects the real picture.
- Name similarities and authors with the same surname. This issue is particularly common for widespread surnames. Other researchers’ articles may appear in your profile, or your own papers may be assigned to someone else.
- Changes in affiliation. When moving to another university or when the institution changes its name, new publications may fail to link to the existing profile.
- Missing publications. Articles may not appear in the profile due to metadata errors, recent indexing of the journal, or an unusual spelling variation of the author’s name.
How can these problems be avoided?
To avoid incorrect h-index calculations, it is essential to properly configure and regularly monitor author profiles in scientometric databases. It is important to combine all variations of your name into a single profile and ensure that new publications are automatically or manually added to your author record.
In Scopus, Web of Science, and Google Scholar, researchers should periodically review their list of publications, remove incorrectly assigned papers belonging to other authors, and confirm their own works. Having a stable author identifier, such as ORCID, significantly reduces the risk of duplicate profiles and data loss.
In addition, it is important to use the same spelling of your name and affiliation in all publications, regardless of the journal or country of publication. This enables databases to correctly link articles to a single profile even if the researcher changes institution. Regular monitoring of profiles and timely correction of inaccuracies help ensure the accurate calculation of the h-index and the complete representation of a researcher’s scientific activity.
The absence of scientific profiles in Scopus, Web of Science, and Google Scholar, or their incorrect maintenance, may result in the loss of citations and slower growth of the h-index. Therefore, proper profile management is an important tool for increasing the visibility of scientific publications and strengthening a researcher’s academic reputation.
