Yeah, I have not done one iota of linkbuilding into my "money maker" page in almost a year. Yet that page and a few other ancillary pages got dinged yesterday.
When I do linkbuilding, it's all high quality links from respected sites.
For almost all of my client sites (non personal), I have seen zero change (good or bad) in the past 24 hours. These clients range widely in their respective niches.
I'm going to go out on a limb here and say that there is some sort of filter in place for over optimization, thanks to the spammer morons out there who ruined it for the rest of us.
