Around 30 days back my site lost traffic about 40%. I guess it is most likely due to algorithmic/ranking issues.But if I see my Search Queries with change in the WMT I see all green and ever increasing without any red's. All the 7000 or so search keywords have infinity increase in change position. Has Google lost the historical search keyword data for my site? Here is copy of those stats. My site is around 3 years old.I'm bit confused as to how to interpret it ...
