Google Slap on April 12th??

I just don’t get Google sometimes, it’s like they don’t want my money.
I have been spending $200/day consistently for about 8 months now on one site. I have lots of keywords and get plenty of clicks with a low CPC (months of hard work to get the CPC’s low). Then, on April 12th, its like they turned off traffic to my site. I didn’t change anything, but all of a sudden i was only able to spend $10-$20 per day. I still get the low CPC’s…but my main keywords barely show up anymore.
There’s no new competition (2 ads for my main keyword) but i still cant show up for less than 10 cent CPC.
What’s the deal???
