A few days ago I made the same discovery. My longstanding site was not being indexed. It started July 8 and dwindled down to just a few clicks in a week. the ‘discourage search engines’ option I had no idea existed, had been checked. I checked with my SEO plugin AIO and they assured me no changes like this could be implemented. Since I unchecked it, a few days ago it has remained unchecked, but clicks have not improved.
