1. Not returned
2. March 14 -
3. 50%-60% from March level traffic. My site was growing at 30% month-on-month till March. Effectively, this is my Nov '09 traffic
4. No problems..always on the growth path
Looks like Google's mocking me of late. A keyword where I used to rank number 1 earlier is shown on top of SERPS during daytime here in India (when the traffic on my site anyway crawls) but as soon as it is daytime in the West (where most of my traffic comes from), another dataset of results show up where my webpage is nowhere to be seen. This has been happening for two days now.
