Gentlemen,
I've been seen a lot of sites do this recently:
Normally this precedes them disappearing from the SERPs.
Some of these sites are mine, and some are ones I track for fun.
I see this happen to sites that are currently having SEO work done to them as well as sites that are having no SEO work done to them.
