In our case, the drop off may have started with older papers. But now, even the newest papers published as recently as this week are no longer appearing in the SERPs.
It used to be very quick for Google to pick up new papers for this site. Now, searching for the exact title of the papers are not yielding the page. Except for:
- the PDF version in the Amazon Web Services URL
- For papers that are still in the homepage's list of most recent papers, then the homepage of the site shows up
- the RSS feed of the issue area, if it still has the paper
- all the other sites that copied the paper
