I am using the OJS {PKP} tool for my journal. Recently, I am facing an issue in indexing with Google Scholar. Google Scholar removed some of my articles from Google Scholar.
It seems like the issue you’re experiencing with Google Scholar not indexing or removing articles might be related to several factors. Based on the information provided and my observations, here are a few potential causes:
Broken URLs: Some of the URLs that were previously indexed by Google Scholar and Google are no longer available. For example:
Incorrect Publication Dates: Some of your articles appear to have inconsistencies between the publication year in the PDF (e.g., 2022) and what is displayed on your site (e.g., 2024). This can cause confusion for indexing services like Google Scholar, which may see these as different articles or may not index them correctly.
Recent Changes: It seems that there have been some changes to your article URLs and files recently. If the structure or naming of these articles has changed, Google Scholar may have trouble recognizing and indexing them.
Suggested Solutions:
Restore or Correct URLs: Ensure that the URLs that were previously indexed are still available and functioning correctly. If they’ve changed, consider implementing 301 redirects from the old URLs to the new ones.
Check and Correct Publication Dates: Verify that the publication dates in your PDFs match those on your site.
Resubmit Your Site to Google: After fixing these issues, you might need to resubmit your site to Google via sitemap for indexing.
