Welcome to WebmasterWorld Guest from 220.127.116.11
In the past two upheavals by Google (8th March 2006 & June 27th 2006)it has been apparent that the changes have been roughly accross the board, with the obvious exception of the 18.104.22.168 DC.
The DC seems to use the same cache dates as the other DC's and has the same amount of supplemental pages also, and yet somehow it has ignored any penalties that have been applied to the other DC's and gives treats my site as though nothing were wrong.
Any idea what the purpose of this DC could be?
All the Best

Many PR8 and PR7 sites are marked down to PR6 and many PR6 sites are PR5s - Sub PR5s dont have many problems.
I wonder if this is a factor in the serps on these data centres we are seeing?
It continues to expand and contract, cyclically, iterative even. This brings me to a untestable crazy theory: maybe this microfilter is being used to temporarily protect sites that might otherwise be caught in a new spam filter, so that the spam filter can be tweaked. I have no evidence for that...just a musing.
Anyhow, we continue to build new sites for our business, and are being careful to make larger titles on this batch that will likely never trip 50% query to title matches -- dumb thing to have to do, but if it helps, then that's what will happen.
When doing a naked 2-word search for one of these subdomains, it is now not coming up at all. And the SERPS have degraded significantly. All the pages coming up have low usage of these 2 keywords in the title and the frequently are NOT immediately adjacent to each other.
One page coming in at #11 is displaying a snippet of text from the first <p> tag on the page for its title in the SERP. This page does have a Title tag in it - but all the title tag has for text is "Home".
Doing a naked search for the other subdomain yields a more "normal" result with high keyword density in the titles. My subdomin in that search is coming up at #4 and has been since 6/27.
Both of these subdomains have the keyword phrase in the URL.
My title tags tend to have a lot of words in them: 4-12.
My top level home page has mostly disappeared from the SERPs. Some days it shows up at around #25 or so (used to be #3 for years). Today it is only showing up at #25 when doing an allintitle search.
Yesterday at this time it was on:
If I had to guess, based on the expansion/contraction, I'd say that 2pm will have 11 datacenters with filtering as a peak, going down to 2 datacenters by 6pm (AZ time).
To summarize, my title is showing as "Blue Widgets World" and the keyword that I was dropped on is "Blue Widgets". Anyone see a similar trend in their titles where their keyword is very close to their title?
It is the first time I have ever noticed google altering a page title except for the maximum length of characters.

I'm not going to get too excited since I saw this briefly on Sunday, only to see the filters creep back in a few hours later. As elated as I'd be for this to be over, I'm a bit disappointed that we never figured out the "why" of it all.
I still think the title is key for those that dropped; if you ranked highly in the allintitle and the query was a close match >66% KW query to title...that seemed to fit thusfar. The geographic stuff made it hard to isolate if this was the case.
I'll check again at 4pm AZ time to see if it is indeed still gone; hopefully I won't be checking all night again.
The only difference I see between us is that your title is being modified on some searches, whereas mine never was. So, one of the filters might be off with others still on. If that's the case, I think the first title filter was on a datacluster level, where the filter you're currently under might be on a IP level (just a guess).
Hey Dazzlindonna, it looks like you were onto something in this collection of microfilters with your title modification/drop theory; smarty.
Hope things stick for you. I am still all over the place. On the DCs where I have disappeared, I always rank high with allintitle, but the allintitle results display the <title> from my site source code rather that the ODP title (Normaly Google is choosing the ODP title over the title in my source code). I am considering using the noodp meta tag to see what happens. I think the title that Google is grabbing from ODP may be what is hurting me. Has anyone been using the noodp tag? I haven't experimented with it yet and wanted to make sure it is not going to make things worse in the long run.
Is it a sign of the future and what's to come? If I knew that, I'd probably have a greater insight to the engine and would probably not be posting much about problems. ;)
Seriously though, I don't know. I think we can expect to see fairly regular data pushes now, at frequent intervals. Whether or not each push will be coupled with microfilters that drive us to the brink of insanity and making us backslide on 3 years worth of dieting...well, that remains to be seen. For now, we can just react to what is going on and try to use that data to anticipate future issues, in an attempt to avoid them altogether.
