Datacenter Watch: 2006-07-21

< continued from [webmasterworld.com...] >

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 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

Col :-)

Hey, did you guys notice there is no option of "language tools" to selec only sites in the USA on the gfe-cw.google.com datacenter?


 4:53 pm on Jul 25, 2006 (gmt 0)

I can't believe it. When I select "only sites listed in the USA" my site disappears. It only shows when I selet UK sites. Grr... What can I do about this? I'm sure that this is the cause of our loss of traffic since June 27th.

The last DC mention by MC is

Somebody knows which DC or group of DC use Google for the last refresh?

Just slightly o/t i notice a certain future page rank tool is marking sites down currently - its looks like new PR is currently being calculated and the new page rank is a lot harder to gain for PR6 upwards.

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?

10am AZ time; here's the two hour update. I should note that the # of results returned on filtered dataset hasn't changed in the last 4 hours, unlike yesterday, where it was changing every 2 or so.

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.

Today 2 of my subdomains show up back at #1 when doing an allintitle search - they didn't yesterday.

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.

>>>The top level home page has mostly disappeared from the SERPs


I did find the top level home page in the SERPS, google has removed everything but first word. So it would appear that the meta title of the home page is involved in this filter.


 7:16 pm on Jul 25, 2006 (gmt 0)

Noon update: spreading again, still no change in result set size. Filters appear on...

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).



 8:56 pm on Jul 25, 2006 (gmt 0)

I am interested in the title of everyone who has been affected. I currently do not use the <META NAME="ROBOTS" CONTENT="NOodp"> tag so Google ignores the <title> tag on my site and takes it from ODP. The title that ODP has for me is three words long and is equivalent to "Blue Widgets World". The keyword that my site was dropped from is equivalent to "Blue Widgets".

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?


 9:02 pm on Jul 25, 2006 (gmt 0)

Yes, it seems to have a lot to do with the page title on your home page. On another SERP, I found my home page and google has actually stripped all the text from the page title except the first word.


It is the first time I have ever noticed google altering a page title except for the maximum length of characters.

Hi Rugles,

Are you using the <META NAME="ROBOTS" CONTENT="NOodp"> to get Google to recognize the title tag on your site, or is it doing that without the tag? Also, is your title the same in ODP (DMOZ) as the the title listed on your site?



 9:08 pm on Jul 25, 2006 (gmt 0)

Is everyone still seeing the filter? I did my usual 2 hour check here at 2pm AZ time and found the following with the filter:

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.



 9:10 pm on Jul 25, 2006 (gmt 0)

No, I am not using that tag.

No, it is different than the OPD. It appears to be my Meta description when I put quotes around the keyword in question. That is different from yesterday.


 9:12 pm on Jul 25, 2006 (gmt 0)

I see the filter still. The IP I am connecting to is


 9:21 pm on Jul 25, 2006 (gmt 0)

Well Rugles, you just helped to confirm that it is query-based filtering too...the filter is completely gone for me on gfe-mc.google.com and the associative 66.102.7.x IPs.

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.



 9:26 pm on Jul 25, 2006 (gmt 0)

Now, is this an experiment by G, or is this a look into the future?


 9:27 pm on Jul 25, 2006 (gmt 0)


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.



 9:45 pm on Jul 25, 2006 (gmt 0)

I'm not an expert on NOODP by any stretch of the imagination, primarily because I don't bother much with dmoz in general. This would be a decent starting point I think:

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.



 10:33 pm on Jul 25, 2006 (gmt 0)

Thanks Cygnus. I hadn't seen that thread. I will try it and let everyone know if it makes a difference.



 11:43 pm on Jul 25, 2006 (gmt 0)

Haven't read the rest os this thread but if there are still some DC watchers out there take a look at

just saw big changes for one of my keywords...


 12:07 am on Jul 26, 2006 (gmt 0)

Another numeric datacenter that stinks, gee more blogs how niiiiice, but it is interesting in that it seems a few more sites are lost on that DC too.


 12:25 am on Jul 26, 2006 (gmt 0)

Well for the keyword in question I was #1 and now I'm #23

#1 and #2 are now two different pages from the same directory and one of the pages links to me heheh

So I guess this won't hold. Results were very relevant for some weeks now with all the top spots pointing to good sites.


 6:17 am on Jul 26, 2006 (gmt 0)

keep an eye at
something's cooking there.Site holding #1 for ages mooved now to #2 while newer site that never made it (until now) to the first page now got the #1.


 6:33 am on Jul 26, 2006 (gmt 0)

This morning I see a specific site vanished while it used to be #1 or #2 on all the DCs for my search phrase. I don't think its a filter effect. Maybe a new "Matt Cutts - Data Refresh" or "Bad Data Push" or... anything else. Who knows of the real reason.... and who cares :-)


 8:07 am on Jul 26, 2006 (gmt 0)

I unfortunately see the same good old link brokers winning the game ... I though they would be off for good this time.


 9:26 am on Jul 26, 2006 (gmt 0)

For what its worth: is also known as gfe-gv4.google.com is also known as gfe-hk.google.com


 9:56 am on Jul 26, 2006 (gmt 0)



However, I prefer the good old numerical IPs ;-)


 11:55 am on Jul 26, 2006 (gmt 0)

I am seeing 3 data sets, common denominator, the spam sites with redirects to paid search, still dominating on all 3.

1. (Not found, found with " " )
2. Found
3. Found + 3 positions higher.


 12:50 pm on Jul 26, 2006 (gmt 0)

Welcome to the club Reseller.

Does your site come back to 1 or 2 with quotes around the search term?


 1:40 pm on Jul 26, 2006 (gmt 0)

Seems as of this morning our keywords are gone on all the DC's. With quotes, we are still there.

Today is also the first day they are showing our NOODP tag has been taken. (It took 7 days)

The club keeps getting bigger.

Anyone find a solution yet?
