I note that the MozCast Weather Report is now showing high change for Monday:
Penguin was for bad boys
I hope you mean that ironically, MrSavage.
My site was trashed by Penguin 1, apparently from a combination of organic backlinks Google didn't like and a big batch of unnatural-looking links that were probably negative SEO posted by a competitor.
It had not been affected by Panda to any noticeable extent.
The fact of my site's SERPs recovery for some key terms today suggests to me that the changes in the last 24 hours have had a strong Penguin element, probably either removing or substantially reducing some penalty factors (probably also removing or reducing any historical element of the penalties). There may well be other elements involved, but for my site it has always been Penguin.
