Hello to everyone.
In the last 2 weeks my website emorroidi.imieirimedinaturali.it has a strange behavior in SERP: it disappears for the keywords ranked and then reappears, and so on.
Here's the chronicle of the last days:
12/6: message in GWT: Improvement of the visibility of the website in search.
12/6 the website disappears for all the keywords ranked
16/6 the website reappears for all the keywords ranked with some keywords higher in ranking
18/6 the website disappears for all the keywords ranked
22/6 the website reappears for all the keywords ranked
24/6 the website disappears for all the keywords ranked...
I can't explain this situation. Could it be a penalty? What Kind?
Thank you.
