September has been spectacular for my two main sites, 65% increase in earning and a large rise in page views. No idea why although my current impression is that G is trying to wipe out a huge number of mom and pop type sites in favour of larger sites. Just a gut feeling I have. G are stupid enough to do this because they believe they will always be the major player - time will alter their view on that.
Some of my EMDs have been wiped out although their earnings were always minimal, just a nasty surprise because they were part of my backup plan. They are still doing fine in Bing though.
