I'm not talking massive drops but what I am saying is on one day we can be 40% UP yet have zero conversions, the next we can be 40% DOWN but have conversions well UP on normal ("normal" being when I could draw the GA chart for the whole week on a Monday & be correct to +- 10 visitors!). Sometimes it's not even over the period of a day(which seems along time at the moment!)in the morning we can be well up or down other times it's the afternoons. Traffic spurts also lead me to believe this is Google, doing nothing all day a for a flood of sales & traffic to arrive in a small(less than 2hr, sometimes half hour!) window? That smacks of some kind of traffic throttling issue to me.
