Hello guys. Anyone any fall with his major keywords down the serp or it is just me? Because 3 of my major keyword have went down the serp (don't know in which page) on the same time. I have only made a new subdomain before this happens 4 days ago and added it to webmaster tool and targeted a country but my main domain does not target any country. Don't know does this thing has something to do with my main website? Some DPs says YES! so how about you?
