See the Google Update History [webmasterworld.com] for details.
There is a major crawl at this time, with some reporting full crawls simultaeously with the start of the update or just prior, while others are not crawled until after the update is complete.
For several months there's been spidering of sites going on all month, even in between the major updates, but this only represents a small percentage of sites and while it may or may not affect ranking changes, it doesn't affect the entire index.
There was a lengthy discussion of what's been called The Everflux Effect early in July:
[webmasterworld.com...]
We've been having a lot of threads starting with questions about this all month long, which makes it hard to find all the relevant information related to it. Also, the volume of posts is making it harder to find other information relevant to Google.
Let's confine discussion of the mid-month spidering and minor update pattern to one thread, to help everyone find the information they need more easily.
Perhaps, I've never been as excited about launching a new site, but I have never seen this and wonder if we did something wrong in the design of the site...or if this is common and I just need to wait a couple days.
As always...Thanks
I launched a site a couple of weeks ago and just last week it was picked up by google. I am assuming that from this point it will take a couple of months for the PR calculation.
In the case of sites already in the database, when there was an ODP update I saw one jump for a few days then go back to the previous position until the very next update.
What they pick up on a regular crawl is generally reflected the following update, other situations can vary.
pagename1.htm is now PR5 like the homepage and pagename2.htm is PR0 - it was apparently discounted, that's my guess. I'm not worried, but I do have to get in there and see what's hanging around to do some housecleaning/deletions of extraneous files.
I'm chalking that up to the possibility of a duplicate / orphan being detected in this case. Yours isn't an orphan, but just out of curiosity, is it almost identical to any other pages?
Look for info in the forums to point them to, may help them understand in the meantime.
Btw, welcome to the forums. :)
I have 3 domains in Google (1 regular domain, and two subdomains). I just searched to check my rankings, and 2 of the 3 are not showing up for their target keywords. I validated that they are in the database, as I can find them when using a more specific search. Both were showing up in the top 20 or higher for their keywords. Now they can't be found in the first 150 for these keywords. PR for both is still showing up as PR5 on the toolbar.
The SERPs seemed to be somewhat jumbled up too.
It gets wierder though.
I found a competitor's site at #50 in the SERP being displayed with the incorrect title, description, and page cache. The competitor's site is about "sales training", yet the title, description and page cache were for an online Meat Market selling chicken and cheese Bratwurst. I clicked through to the url, and sure enough it took me to the sales training site (sorry, no Bratwurst there!). This particular site is in ODP and the Google directory. The Google directory was listed correctly along with the incorrect title and description.
Anybody else seeing major ranking drops/disappearances or strange SERP description results?
If anyone wants to see a screen shot of 'sales training site'= Meat Market description swap I referred to above then stickymail me.
I have noticed since the July update (approx July 24) that Google seems to be cycling the results through 2-3 different indices AFTER the update has stabilized. All during August I checked my rankings. Almost everytime I checked I would be in a different position, but it was always one of three specific positions with the top 20. I am seeing similar cycling so far since the August update.
This leads me to believe that they are cycling different versions of the index into the results to make the database appears more dynamic/less static.
Has anyone noticed a cycling or rotation of different results inbetween updates?

Yes, for my one main keyword, www2 and www3 I see constant rotation. I am mainly in #7 on www2 and www3 and #11 on www. www2 and www3 occasionally cycle onto www, but mostly not. This is frustrating because I don't understand why www2 and www3 never permanently reside on www for this keyword.

To anyone who linked a few sites together:
Were they appearing highly and are now greyed out/disappeared from SERPs? Check your IP Class C subnets........
If they're all the same, thats your problem
-----------------------------------------------------------------
Is there much truth to this? I do indeed have a couple of sites,
all linked together. As you might have seen from an earlier post on
this thread. They're all new sites. Were spidered by Googlebot, showed up high on a listing for its relevant keywords, had stayed on for a few days, but has since disappeared from the index. I've been
told this is a common phenomonon, and should sort itslef out with the next update (which i am fine with), however, they are all served from the same host. I do a ping and all four of em, even return the same IP, that as well puzzles me...but do you think the sites disappeared because they're new and they're just going through the processes before being added with the next update? or might they have disappeared because of the validity of the statement above?
thanks for your thoughts on this....
I know of 20 sites all x-linked on separate domains. #1&2 for extremely competitive terms over a very long period. Now #437&438 (give or take)
No spam, no "above-the-radar" tricks used. But all showing same class C block. All dumped. The sites are very well established so its not because they're new.

thanks for replying. My sites are all hosted with one of those cheaper host providers. Having pinged each of the four, i realised they come back with the same IP. They're clean, no "above the radar" tricks. Do you think the same fate may await me? I know also, that Google doesn't list more than two pages from the same domain when a search is performed. Though all my sites have the same IP they have different domain names...does it look at the domain name or the IP when determining which two it'll throw up on the list.
Also, if you would kindly read my first post on this thread, in your opinion, was my site (being brand new, and spidered for the first time) 'temporarily' removed until the next update? or do i need to worry,they being on the same IP.
Also, what do you think i should do....get a new host? if i do, would google easily find me on my new IP?
thanks again
I think this has changed but if I'm way off-mark, someone please let me know.
RobPike, if I were you, I'd use a different class C for each domain and leave everything else alone & see what happens.
I don't know if G shows IP or domain. Domain is far more likely I'd have thought.
J
If you were to use a meta or javascript redirect, G will index the page the redirect is pointing to. Best to use a 301 server-side redirect though to avoid any penalties here.
J
Oké, this is my situation same as RobPike.
I have 3 highly optimized dutch spoken portals. Site A is my main site, site B is a help portal build on php with Mysql, and site C is BRAND new and is a portal about search engines en especially Google.
Now:
1) Site C (new one) has had the Googlefriend visit on 27 and 28/08 only 2 day after submitting it (me off course very happy :-)
2) Almost each day the last 4 days my sites have had the visit of the bot.
3) My brandnew site which was highly positioned after the primar index is dropped... no where to be seen in the index.
4) Site C and B are both on the same IP adres but alas, to make thing difficult. My hoster changed the servers IP adres,... this weekend.
So IP 1 and new IP2 are both pointing to site C and B.
My question:
1) Same IP address: I've read GoogleGuy's response but it's dated from 2001. As I understand this is a misty affair?
2) The brand new site is havilly concentrated on Google and SEO. I use a php CRM package to maintain the site. Could it be possible that the Google algo 'weights' the number of times the word Google is found on a site. Because if so I'm cooked...
Please mail me and I'll post the URL of site C....
I'll grab an aspirine and wait a couple of days but I hope I didn't get banned. Would not be a master marketing idea: SEO's site banned from Google... Tsss I wouldn't want to dream about it :-)
grtz
