I have been monitoring a keyword for a long time. until a few days ago, I was #4 no matter where I checked from. but the last few days, I am #1 if I check from home. If I go to coffee shops around my house and check, I will be #4 just like usual. this is not a cookie issue. I have cleared history. I have opened a private window. I have tried different browsers. I have tried different laptops. same result. I don't have any google products installed on this site. I dont have analytics, I dont have google places, nothing. I dont get this, what is going on?
