Are you talking about b2evo stats? Try to add Google Analytics and see if It shows similar results.

Yup. Yesterday: 28 visits (my last "normal" sunday 198) , total Adsense income 50% down for the period. I have had 2 consecutive days with 0,00 Adsense income, which had not happened in the last 2 1/2 years!
Bevo stats for yesterday: search hits 15 (down from 200+; referrer hits 4 (down from 20-35), direct hits: 37 (down from 150-200) and self referred 56 (down from between 200-400).
I'm really desperate. Even if the Google algorithm change were to affect me really badly in one way or another, why would direct hits be down too?

Do you see anything odd in error logs?
It looks like your website lost positions in google. I don't know why direct hits went down too.

Nothing odd in the error log, but you're right: I've lost Google almost completely. Any clues on why that might have happened?
Or better still, what I might do to fix this?

Here's the answer

My website lost 50% of traffic and income too. I have no idea as how to get it back.

If I find something I'll let you know. A lot of people complaining on the web.
I for one am not guilty of keyword stuffing or content spinning, the two capital sins for Google.
I will reduce the size of the header to see if that helps any, but still digging for some explanation from Google on how legit sites may get their traffic back.
By the by, I understand that Google pushed out the latest algorithm on april 24th, which coincides with my big, bad drop.
