Earlier when I happen to find the problem (all this can be skipped)::

After several months of loosing users, today I found that my site has been blocked/forbiden to Google !!!

More Earlier, how I found this problem, all can be skipped:

I did read almost all of this meta topic before asking.

In Aug2024, I noted that traffic to my website has reduced up to 95%. But I ignored it thinking that may be I wasn’t posting enough.

Bt today I found that whatever term I might search on google, restricting the search to my own site only: ***site:BathindaHelper.com jobs in bathinda*** , it was giving ZERO result (the single result it is showing from my site is actually just a suggestion that I create google ads to show this result from my site, which indicates that my site HAS indeed been indexed):

The image shows a paused Google ad campaign for "BathindaHelper.com jobs in Bathinda" on a search page, with a summary indicating that the ads are not showing due to the campaign being paused and an option to "Resume" the campaign. (Captioned by AI)

And finally I also checked Google Analytics (perpahs renamed to Google Events) and it s clearly showing that from 17 June, 2024 Google isn’t referring my site any more.
