I was thinking about an issue! “Self citation”. Do you have any case regarding self citation?
Which means cited articles which are published in your journal. If you have any thought, let me know please.
If you get any positive feedback, please don’t forget to share.
Many authors have bee suffering regarding this issue from my side
we are facing the same issue like you, checked everything and did not find any issue
We have lost scholar indexing with our rest of the publisher houses. Most precisely every article has vanished which are published after June 20, 2024!
Hello all,
PKP does not have any special insight into how Google Scholar operates. The Google Scholar plugin for OJS just adds meta tags to the article pages that Google Scholar can index when it crawls your journal website. You can verify that the meta tags are in place by looking at an article’s landing page and looking for meta tags that look like this:
If those tags are present in your page source, then the OJS Google Scholar plugin is working properly.
From there, it’s up to Google Scholar to find and index the content. Again, we have no control over this or insight into how it works. We won’t be able help answer questions about why your journal is or isn’t indexed.

Please Help me too mu all articles deindexed from Google scholar our journals are also not on Google Scholar now
gassjournals.com
please have a look and tell me how I can fix it
I don’t know if this will help or if there’s something else going on, but I’d suggest
- Register your site with
search.google.com and analytics.google.com.
A lot of people don’t do that. - Add Schema.org markup and Open Graph meta tags to your site, especially articles.
@rcgillis The Google Scholar Indexing documentation has an outdated link for reference 2 “Indexing repositories: pitfalls and best practices” (in the last chapter).
The reference can be found best in Zenodo (which stores all Open Repositories contributions), at https://doi.org/10.5281/zenodo.6521981 . Please replace with this link.
Hi @mpbraendle,
Thanks for pointing this out. Have made the correction: Corrected Link to Indexing Repositories document by rcgillis · Pull Request #1270 · pkp/pkp-docs · GitHub (it may take a bit before its merged and the docs hub is reindexed to reflect the correction).

Hi @Abdul_Samad,
I guess one of the reasons that Google Scholar deindexed your journals is that the articles don’t have a DOI. I suggest that you first register your journals with Crossref (they already do have an ISSN, so one prerequisite is fullfilled) and then deposit the articles. While this involves some cost, it will help them a lot for findability and visibility of the articles and persistent reference. Also, other databases profit from Crossref metadata and visibility of your journals will be increased.
Thank you for your suggestion regarding Crossref registration and DOI assignment. While having DOIs for articles is indeed beneficial for visibility and findability, we do not believe that the absence of DOIs is the primary cause of this specific issue.
Our journals, which previously had all articles indexed on Google Scholar (including those with assigned DOIs), have recently encountered a problem where not only are new articles no longer being indexed, but previously indexed articles have also disappeared from the Google Scholar database. This issue is not isolated to a single journal; we have observed it across multiple journals, even those fully compliant with Google Scholar guidelines and equipped with DOIs.
We suspect that this problem may stem from recent changes on Google Scholar’s side, as OJS has historically been compatible with their indexing requirements. Despite reaching out to Google Scholar multiple times for clarification, we have yet to receive a response.
We are actively investigating the issue to determine the root cause and will continue to share updates as we make progress. If anyone else has encountered similar issues or has insights into this, we would greatly appreciate your input.

Did any one get any clue that how we can resolve deindexing problem?
still learning bro, i have try many ways, but still didnt solved
please someone help
would you like to explain about schema.org ? what should we do in this site?
Here is one of our journals, look at the source code
https://universaljurnal.uz/index.php/jurnal/article/view/1428
There is more information here
https://schema.org/Article
Don’t forget to register your magazine in google
I also recommend making Open Graph tags.
Many people in this conversation are dealing with the same issue: Google Scholar has removed their articles and journals from its database, and attempts to contact them are met with no response. I have been working in the industry for over 7+ years as a tech professional (specializing in journal website development), and I’ve tried everything to resolve this problem.
Recently, I connected with someone facing the same issue, and after discussing it, they shared that Google Scholar has been removing a lot of journals from its database. This is often because Google Scholar flags them as “predatory,” or sometimes due to uncertainty about the quality of the journal’s content. Based on my experience, this seems to be a likely cause.
In the past, I developed over 50+ custom-coded websites (without OJS) for clients, ensuring I included all necessary tags for Google Scholar indexing. Initially, the indexing worked fine, but over time, Google Scholar removed all the indexed articles from those custom-coded websites.
I initially thought the issue was related to my custom-coded websites, so I tried running 1-2 journals on OJS to index the articles. For 2-3 months, it worked and the articles were indexed. However, after 4-5 months, Google Scholar removed those articles and journals as well.
Based on my observations, it seems there’s an algorithm at work behind the scenes in Google Scholar that filters journal quality. This suggests that the issue lies with how Google Scholar evaluates journals and articles, rather than with OJS or custom coding.
To further address the issue, I created an article-sharing platform (similar to Academia.edu and ResearchGate) to help index articles. This worked for a while, but after about 6 months, Google Scholar removed all the indexed articles again.
Additionally, I tried changing my hosting provider. Sometimes, if a server’s IP address is blacklisted or flagged by Google Scholar as spam, it may prevent indexing for other journals and articles hosted on the same IP. I thought this might be the issue, so I switched hosting, and it worked for 3-4 months. However, after that, the problem returned, and Google Scholar removed our articles once again.
I know this might sound surprising, but if you’d like to verify my experience, feel free to check my LinkedIn profile (LinkedIn Profile: https://www.linkedin.com/in/yogeshsinghbisht/) and portfolio website (Portfolio Website).
To clarify, this issue is not related to PKP OJS.

I believe that you are correct that Google Scholar is using their own metrics and features to decide what to include. The concept of “quality” is ambiguous, but classical ranking methods are usually based on bibliometrics involving bibliographic citations. Those have unfortunately become subject to manipulation just like the original PageRank algorithm. If a paper receives no citations then it’s very unlikely to get listed in Google Scholar unless it is part of a journal that regularly receives offsite bibliographic references and are not self-citations by the same authors. Sometimes only a subset of the papers from a journal will be listed in Google Scholar.
Note that there are a lot of articles that get published and receive no citations at all. It varies quite a bit from one field to another. Everyone wants recognition for their work, but it isn’t distributed uniformly to everything that is published.
