Hi all Not sure this thing happened just today or when. but when i try to input the keywords of my site to check the SE ranking result, I found that the keywords that used to have like 36,000,000 results only show 16,000,000 results and 2,000,000+ keywords result now only got like 400,000 results!! Fortunately my ranking still in the same postition (Top 10 in most keywords) but i'm not sure what just happened. Can anyone explain this?
