In this case, there is only one solution. It is to specify in the code, meta tags, or somewhere else that this is not a journal, but a repository.
I draw a parallel with EPrints or DSpace.
All our articles uploaded to the platform where the EPrints repository is installed have been in Google Scholar for years.
Now we need to think about how to do this.
Do I get it right that you have a parallel repository in EPrints that contains the same content as in OJS, and gets indexed in Scholar from there?

The EPrints repository does not belong to our organization. It operates for many institutions. We are simply required to submit our articles, monographs, theses, etc., there.
Hereās the thing: if you submit an article, monograph, thesis, etc., it will appear in Google Scholar, but the journalās website does not recognize it in any way.
After writing the post, I visited a Scopus Q2, Web of Science journal: https://journals.sub.uni-hamburg.de/hup2/ijrvet/article/view/1394
This journal is also missing from Google Scholar
But, to my surprise, I found an article from it: https://journals.sub.uni-hamburg.de/hup2/ijrvet/article/view/1394
Here: Google ŠŠŗŠ°Š“ŠµŠ¼ŃŃ
And when we go to the site, itās EPrint.

Hi @Oleksandr_Radkevych, @asmecher, @kmccurley,
our experience is different:
Google Scholar coverage of our journal platform is near 100%. Even articles that have no citations and even very young journals. So I donāt think citations are the quality indicator GS takes.
Google Scholar coverage of our EPrints repository stagnates at about 30%, although we have tried many different measures to improve that ratio.
I agree with @openaccessjournals that there might be some quality algorithm by GS that works on content. I see this especially for one journal that has mixed content: scientific content is being indexed very quickly, community content is not (which is correct in my opinion).
New journals are indexing normally. But after sometime same indexing problem with the new journals also.
im so interest this explanation.
is possible to combine this solution with proxy in config.inc.php ?
here the code
[proxy]
; Note that allow_url_fopen must be set to Off before these proxy settings
; will take effect.
; The HTTP proxy configuration to use
; http_host = localhost
; http_port = 80
; proxy_username = username
; proxy_password = password
is this make our journal get new IP Address?
Interesting approach. The question is which proxy to use. Free or paid, within the country or outside it. Should the IP be static or dynamic?
Hi all,
Those proxy settings are for OJS to be able to make outgoing connections, when a proxy is needed. I donāt think thatās what youāre looking for.

I read the openaccessjournals commentar above sir.
maybe proxy able as a solution for Google Scholar issue
Our new journals were indexed properly also having doi and ISSN but after 3 months yesterday I saw that the latest issue of our all journals were deindexed only previous issue is available on Google Scholar. Still I am not getting the proper sloution of this. There is repository named as Neliti.com from there our few journal papers are indexed but not from our site
@asmecher The repository link given by @Oleksandr_Radkevych below is from the University of Zurichās ZORA repository. One of the authors is from University of Zurich and was allowed to deposit the article there.
Google Scholar indeed indexes the article below from OJS, see
https://scholar.google.com/scholar?hl=en&as_sdt=2007&q=10.13152%2FIJRVET.12.2.1
then click on ā2 versionsā. The second version is from journals.sub.uni-hamburg.de
However, what I see from gs header data in the OJS article is that the element citation_abstract is missing (although the abstract is present in the article details page at https://doi.org/10.13152/IJRVET.12.2.1). Might there be specific reasons why the abstract is not exported by the GS plugin?
Hi @mpbraendle,
The <meta name="citation_abstract" ...> element is excluded if the article doesnāt have an abstract.

Alec Smecher
Public Knowledge Project Team
Yes, but on https://doi.org/10.13152/IJRVET.12.2.1 there is an abstract, but no <meta name="citation_abstract" ...> element. Thatās why I am asking.
Hi @mpbraendle,
Ah, thatās OJS 3.3.0-x. The Google Scholar plugin for OJS 3.3.0-x does not include the citation_abstract meta tag; it was added for 3.4.0 with this change.
@bozana, do you remember why the citation_abstract was added? Was this a new Scholar requirement? (Perhaps we should back-port it to stable-3_3_0 too.)
Regards,
Alec Smecher
Public Knowledge Project Team
Oh, @asmecher, I do not remember any more 
In any case, when we initially added Google Scholar support, this wasnāt a requirement ā and still isnāt documented as one in the scanty Scholar meta tag documentation. Scholar has reviewed our meta tags for 3.3 and 3.4.

My experience is almost identical to yours. We also developed our website, and with the exact same technology stack and parameters, some journals are indexed while others are not. Therefore, I believe this is definitely not a technical issue.
Yes, because the code functions the same for all websites, journals, and articles.
Anyone get any sloution or at least the issue why journals are getting deindex?
We are checking AI and copy materials from turnitin before publication still journals are getting deindex after few time. We are not doing self citations we have doi still our some new journals again deindex
GS problem is still there. I am also facing this issue since more than 6 months. I also email to gs 2-3 times but no reply.
