Google Scholar Indexing Issue

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

  1. Register your site with
    search.google.com and analytics.google.com.
    A lot of people don’t do that.
  2. Add Schema.org markup and Open Graph meta tags to your site, especially articles.

I did everything but no use

@rcgillis The Google Scholar Indexing documentation has an outdated link for reference 2 “Indexing repositories: pitfalls and best practices” (in the last chapter).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.
