An alarming trend that still hasn't corrected itself. I have 6 sites on a server and April 18/19 this year something happened that I cant figure out.
Traffic dropped by about 75% on all of them. SERPs dropped big time. from top ten to 50-60 range.
My first thought and still most logical one is server was hacked - which has happened before despite my attempts to secure...
I am in process of cleaning everything with new directories, fresh installs of WordPress and fresh plugin download installs, etc.
Can you think of something else that would affect all the sites on server do drastically? Any advice to turn around?
The sites are older established and good content so don't think being penalized.
