Hello.. This happened to 4 of my sites, almost simultaneously. 80% of my content are unique, and most of the money keywords were on page one (#3-#10) previously my pages were not optimized at all, like loading 10sec for a important money page. I placed that site on cloudflare and MAXCDN, plus also changed the host. optimized to the max with W3tc....hoping SERP will increase... but got this instead: (IMAGE FROM WEBMASTER TOOL) i have same image for 3 other sites. Now for one of them, i did not optimized page loading. and didn't put that on CDN, but still got slapped. now, my thought is: changing host caused this. even after 11 days, my pages are dropping like rock. A super converting page, that was on #3, is now in 198. but that keyword is not pointing to original url, instead that's pointing to my homepage. one thing I must add, non of the pages are de-indexed. most of the keywords are now resting behind #200. which never happened to me before for google dance. If you guys have any advice please share. and if this is google dance, how long it might last?
