I'm discussing about one of my site's penalization in other thread but this thread is completely different and I'm seeing a strange thing.
For 4 target keywords, one page of my site example dot com/abc.html was ranking on Page #1 for several months.
About one week ago, my page 1 rankings (sitewide) disappeared and now for those 4 target keywords, I've 3 different pages ranking. Not on page 1 but Page 5.
The main thing is, those pages have no backlinks at all. I'm tracking rank and this happened exactly on the same day when rankings dropped.
To make it more clear, right target page was ranking for 4 terms correctly. Then one day, rankings vanished and incorrect pages start ranking. The pages are kinda switching. One day correct page ranks and then another day, incorrect page ranks.
I was thinking If it is a penalty or something else? Very strange and I'm really learning a lot with all these sitewide penalties.
