I saw on many forums many people reporting a drop in index and rankings as well, so does this mean Caffeine is roll out or something?
No you can't just say Caffeine is shooting out. There could be number of reasons regarding indexing & ranking.
I've checked plenty of websites - and none of them have been affected. I've tried to find affected websites just to see, but they must be such a small percent, lol.
I think like most things that they do it's done on such a huge scale the changes are rolled out systematically. There are lots of reports from within our industry of major fluctuations starting as far back as 1/2010.
I don't think there's any way to know for sure unless Google releases a statement. That said, I'm glad the results are changing as I've moved up about fifteen spaces in the past ten days.
Typically before a big update there are large variations in search results, but it typically only lasts a few days then things settle down and return to normal.
mabey google didnt like some of the backlinks mabey spam who knows thats why i am doing my links manually dont want to take a chance. may take 14 hour days but worth it in the long runn.
