when search in google,some result's belower have some words like"- 6 visits - Feb 28". I want to know what's the signs mean? And why others no appear?
when you sign in google account & search with google, google saved search informations. If you sign in google account from a computer & other people search from same computer, other people's search information will be saved on your account.
Everybody has already told you. You're signed into a google account and it's showing you your own search history. Look for your search history in your google account and it will match it.
Yeah it's Google personalized search history as people have said, go to "My Account" in the top right of your Google homepage then "Web History" and disable it.
