maybe the wave haven't reach to my country? but I didn't see any sign of my ranking drop in google US (google.com) either. My ranking technique is a bit shady, 80% link packages in BHW, 20% natural. I think I want to conclude in 2 things. 1. my link profile looks is much more make sense. - although I blast lots of BH links but the timing was perfect to gain many good and natural links. 2. my on-page is perfect. - My other site which I try to rank with the exact link building for my first site didn't get hit. 3 kws in page #1 within 2 months, but my content is solid, and silo type. I mix them around with common sense thing like social presence and responsive theme.
