but I sure can't catch Google "disappearing" my sites from the SERPs even for a minute
On a couple occasions, I've seen this happen for the keywords I track, but it's only been a couple times and my site comes back when I go back to look again. It's hard to catch because the first thought we have is that the site is just ranking lower on that particular search. Then we still don't see it and go back, but it's showing up by that point.
I've recently wondered if Google has a problem where it thinks multiple pages ought to rank in the same position but it obviously can't show more than one site in the same position at the same time, so it will allot some time to one site and some time to another site and so forth.
