When a site is volatile with it's results in the SERP's it would seem to mean that either the competitive efforts of other sites is a factor, or , the site is sliding below a "trust" threshold where Google re invokes it's filters. Different DC's would presumably be tweaked to different levels and thisis where the movement between DC's may have it's exposing effects.
Those filters likely comprise of the sorts of things that you describe to revalidate it.
Sites like Yahoo Answers , Gumtree etc have a high trust ranking with Google and refresh very quickly, probably not just because they are well known, but a whole host of other factors which validate the trust.
I'm noticing Yahoo Answers at the top of the SERP's and there is no visible PR.

I have noticed the same thing.
My blog seems to come and go for various terms.
Interesting enough the terms in the domain name also come and go.
I chose the domain name to represent some terms that were interesting to me, and now those terms only seem to rank on google.fr
Dunno, back to the drawingboard I guess..

Whitey sorry what do you mean by DC.

I have just added a load of content to a long-existing site and its rankings have disappeared. I'll post back to this thread should my site get its rankings back.

DC = Datacentres , one of many data centres that Google uses.
Different data centres may produce different results, with some filters tweaked higher. Hence the variations in the vulnerabile areas of a site. IMO

Exactly the same thing i am seeing here. websites that i lost interest in updating them are ranking where they should be now but for those that i work hard on them, tends to swing around the top pages to no where.
Previously i thought it was related to supplementary results but yesterday, my site just disappeared from the Google SERP (after i add in some new contents and new links on the homepage)...
Wonder does it means doing less is more to Google? definately not an idea appreciate by my site visitors.

now what is this yoyo effect
| 2:22 am on Feb 28, 2007 (gmt 0)|
Yo yo effects (in my dictionary): Top 3 spots in SERP over ALL Google DC this month, no where to be found on next month. I've been experiencing this for quite some time.
One question for those who experience the same thing: Does your website remains top ranking for certain keyphrase? Mine does. for a few keyphrases, the said website remain #1 no matter how it performs in other search phrase...

Yes, I have seen this too. For a few competitive phrases my site is still number 1. For others (including the name of the company) we have all but disappeared.

Don't agree ...
I see a lot of competitors, who just bought old domain, then make new content and they are at top now.
So new content <> new domain.
Age of domain is very important, if it stays in google index and doesn't go "parking" or expired.
