There can be several reasons why new citations to your paper may not show up in Google Scholar immediately. Here are some possible explanations:
Delay in indexing: It can take some time for Google Scholar to index new citations. The indexing process can take several days or even weeks, depending on the frequency of updates to the database.
Citation format: Google Scholar may not recognize certain citation formats, such as non-standard or incomplete citations. Make sure that the citing authors have provided a complete and accurate citation, including the title, author names, publication date, and journal or conference name.
Citing article is not indexed: If the citing article is not indexed in Google Scholar, the citation may not appear in your profile. In this case, you can try to manually add the citation to your profile by clicking on the "Add article" button in your Google Scholar profile and entering the citation details.
Duplicate publications: If the citing article is a duplicate publication of your paper (e.g., a conference paper that was later published as a journal article), Google Scholar may not count it as a new citation. In this case, the citation may already be included in your profile as part of the original publication.
If you are still experiencing issues with citations not appearing in your Google Scholar profile, you can contact Google Scholar support for assistance.
wait in indexing: Because Google Scholar adds new citations to its database on a regular basis, there may be a wait before your paper's new citations appear in the system. It's possible that the citations will eventually surface in Google Scholar.
Citation style: Citations may not be indexed by Google Scholar if they don't follow a given style guide or if they don't satisfy certain requirements. Make that your paper's citations are in a format that Google Scholar can understand and contain all the relevant details, including the authors' names, the title of the publication, the year, and the page numbers.
Self-citations may not be included in Google Scholar's citation count, thus if the new citations come from your own work, they might not be reflected in the total.
Source reliability: Citations from questionable or predatory sources may not be indexed by Google Scholar, which gives priority to reliable sources. Ensure that the references to your work are coming from reliable, trustworthy sources.It's likely that the new citations are not appearing because they are not accessible to the general public if your Google Scholar profile is set to private.
There could be several reasons why new citations to your paper are not showing up in Google Scholar:
Indexing Delay: Google Scholar doesn't index new citations instantly. It can take some time for Google Scholar to discover and index new citations to your paper. This delay can vary, but it's not unusual for it to take several weeks or even months for citations to appear.
Citation Format: Google Scholar relies on proper citation formats to identify and index citations accurately. If the citing paper doesn't follow a standard citation style or if the citation is incomplete or incorrect, it might not be recognized by Google Scholar.
Citation Source: Google Scholar primarily indexes academic and scholarly sources. If the citing paper is not from a reputable academic or scholarly source, it might not be included in Google Scholar's database.
Access to Full Text: Google Scholar often requires access to the full text of the citing paper to accurately index citations. If the citing paper is behind a paywall or not freely available online, it may not be indexed.
Privacy Settings: Check your Google Scholar profile settings. Make sure your profile is set up correctly, and you've added your publications to your profile. If your paper is not associated with your profile, citations may not be attributed to you.
Inaccurate Metadata: Ensure that the metadata associated with your paper (title, authors, publication date, etc.) in Google Scholar is accurate. If there are discrepancies, it might affect how citations are linked to your paper.
Patience: Lastly, sometimes it's a matter of patience. As mentioned earlier, Google Scholar's indexing process can take time, and not all citations may appear immediately.
If you believe that your paper has received citations that are not showing up in Google Scholar, you can try waiting for some time to see if they eventually appear. You can also double-check the citing papers to ensure they are properly formatted and come from reputable sources. Additionally, make sure your own Google Scholar profile is set up correctly and includes your publications.
the paper cited in 2021 in a well reputed journal still does not appear in google scholar citation....it does not seem to be only about source, or patience!
Google Scholar typically updates its citation database periodically, and it may take some time for new citations to appear. Several factors can influence when and how citations to your paper are indexed and displayed on Google Scholar:
Publication Date: Google Scholar may prioritize indexing and displaying citations to recently published papers more quickly. Older papers might not receive real-time updates.
Source: Citations from reputable sources, such as peer-reviewed journals, may be indexed faster than citations from less authoritative sources.
Indexing Frequency: Google Scholar updates its database at irregular intervals, so there is no fixed schedule for when new citations are added. This can result in variations in when citations appear.
Publisher and DOI: Papers published by journals with strong online presences and papers with DOIs (Digital Object Identifiers) may be indexed more promptly.
Author Profiles: If you have a Google Scholar profile and you've claimed your publications, citations to your papers may be associated with your profile more quickly.
Citation Source: Citations from scholarly articles, conference proceedings, and reputable websites are more likely to be indexed compared to citations from personal blogs or less reputable sources.
To improve the visibility and indexing of your paper's citations on Google Scholar, consider the following steps:
Ensure that your paper is properly formatted with complete citation information, including titles, authors, publication sources, and publication dates.
Encourage colleagues and collaborators to cite your work in their research papers and publications.
Claim and verify your author profile on Google Scholar if you haven't already done so. This can help Google Scholar associate citations with your profile.
Provide accurate and complete metadata for your papers when submitting them to academic databases and repositories.
Be patient, as indexing and updating processes can vary, and it may take some time for citations to appear.
Remember that Google Scholar aims to be comprehensive, but it may not include every citation to your work, especially if the source is not easily accessible or if it is not from a scholarly or reputable source. If you continue to experience issues with the visibility of citations to your paper, you can reach out to Google Scholar support for assistance.
With regards to missing citations on my GS account, I think it is none of the reasons given above. I am wondering if GS has changed some of its search algorithm settings?
I currently have a list of 12 full-text PDF published academic articles, which site my work, not showing up on my GS account. Five of these articles have been added to my citation count on Scopus. As some of you would be aware, Scopus has a focus on quality peer-reviewed articles, with many checks before citations are added.
In my opinion, GS used to pickup most published academic articles (regardless of quality) but I now have evidence it is not picking up articles being listed in Scopus. Something very odd seems to be happening with GS.
Please ignore this if someone has already responded to you. In my case (more than once), the journals (top international journals!) that cited my work split my article's DOI. Then, I had to report the journal that published my paper about the issue. My journal contacted the paper citing my article and asked them to correct the incorrect DOI. Once the DOIs were fixed, the issue was resolved. You can see the citation appear in your ResearchGate and Google Scholar in a couple of days. But remember that I am talking about citation in top tier journals!
