Sudden loss of ranking of every single keyword - is this normal?

[dereck]

My situation is that every single of my keywords has dropped since Thursday or Friday. I used to have roughly 20 low search volume keywords on page one of google - now they are are around the 100th page. Not a single one has survived. My search engine results are near zero.

So, it's not that one or two keywords have lost ranking and I can just focus on the other ones or new ones. It's my entire site.

Have you heard that before?

I can not imagine that this should be normal as it would put anybody completely out of business.

I have filed for reconsideration in webmaster tools.

I have no duplicate sites, no dodgy methods, only original content - everything looks fine in webmaster tools.

I have heard that this is 'normal' but can't imagine it is becasue it would kill anybody's business.
