We operate a unique content article website and publish daily.
48 hours ago we published a group of 5 articles regarding an upcoming musical concert.
Then came in Google's strange indexing practice...
1) it shows all 5 articles in index, rating very high - visitors are coming
2) it drops all 5 articles from index. They are nowhere to be found, even searching "exact sentence or title" shows nothing. No more visitors.
3) it goes right back to step number 1. and keeps repeating the cycle every 6-7 hours.
Is this something that happens from time to time and what might be causing it?
I've been publishing articles for years now and don't believe I've noticed such behavior (maybe I wasn't paying attention)
Google recognizes our site as it has been around for almost a decade now. Usually whatever we publish appears in index under 5 minutes.
