Terrible for us today too, infact this week has been the worst in ages(on the back of an excellent week last week(apart from Friday)-go figure!). The SERP's always look good for us so it comes down to what Google is sending us. Our one site has had the SAME number of visitors every day this week! Traffic throttling problem?
