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:
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.
I was wondering if the "everflux effect" affected all sites or just newly included ones - and if it ever settles down?
One of my sites was created around the 1st week of July and was included in the July update at #10 for my main phrase. It stayed that way w/o change until the August update, at which time it bounced between #6 and #7 for the same phrase during the dance and then around the end of August, dropped off the face of the planet. :-(
The strange thing is, during the dance, it was NOWHERE to be found in www3 and www2, but still was bouncing on 6 or 7 in www (up from it's pre-dance position).
Now it pops in and out of www at 6 or 7 about 2 or 3 times a day and then disappears the rest of the day, and on www2/3 it has moved to page 2 and is steadily climbing up.
What gives here? Is this everflux or just some weird "glitch" that I wish would happen on any search engine OTHER than Google since I REALLY like those brief shining moments at #6. ;-)
I would not worry if you have multiple sites on one IP address, if you do things that Google don't like then using different IPs doesn't help in my experience.
Changing IP address is often a problem, you may disappear from Google for a month or even two.
I would be very surprised if Gooogle penalised you for mentioning Google too often. Of course linking to SEO sites (especially those penalised for link farming) is another matter.
How about if you've been ranked top for over a year for highly competitive KWs, are not doing anything spammy, yet you've just been dumped in the SERPs???
This is the situation for a company I know of with 20 sites. The only remotely bad thing they do as far as I can see is have them spread across the same 3-4 IPs. Nothing else.
Any clues? can stickymail you the url but its very standard
I've spammed. I didn't know how I was spamming until after my PR0 penalty. I've learned my lesson and to be on topic - I have several new domains with a cache date of September 8th... and I am showing high in the serps but history shows me that just because my site is caught up in the ever-flux it doesn't mean I will be in the update at the same position next month during the normal update.
1) Google now is using multiple indices that alternate all month long between updates. I believe that there are 2 or 3 of these indices.
2) Each of these indices is subject to minor but constant ongoing change between updates (what we've dubbed the everflux effect).
Conclusion #1 is very significant as it is a new wrinkle in how Google works. It has been going on for at least two update cycles from what I can tell.
I believe that this is the latest manifestation of Google's desire to have more frequent updates. It isn't really more frequent, but the results would appear to be more dynamic to the non-SEO-geek-observer. :)
1. Google updates every 2-4 days
2. Each update usually includes pages from 2 dates. For example, this update includes Sept 9 and Sept 10th.
3. Pages older than 2-3 days lose the fresh date. For example, the pages that said Sept 8 no longer say anything.
4. Contrary to some comments I've seen, there are not any pages that get a daily update.
5. Placing a link on a page that is refreshed on every update causes the linked page to get updated most of the time.
This is what I am talking about. Google is alternating results between 2 or 3 different indexes. Do the same search over different times of the day, and over a few days and you'll see what I mean.
For a given search, you'll generally notice a pattern of 2 or 3 different total results, as well as different rankings.
This has been going on for at least 2 mos. now.
Within days literally, it was ranking no.2 for my target keyword. It had a fresh tag beside it. Now just 2-3 days later it has completely gone!
Could someone please inform me on if I have done something wrong, or if this is usual. I am suspecting that it has dropped out because it is no longer fresh, but wasn't in the actual database yet. I am hoping I am not being penalised.
Thanks in advance!
This month something that I never have seen before happened. A new site which I put up in the end of last month (hoping to be in this months update) started geting traffic from google. I was surprised and checked google. And to my surprise the indexpage was in the database...this was one week ago. Today I checked and another 30 pages had made it into Google.
Anybody else experienced this?
I have a new site that google has picked up but its only displaying the main index page in the results, is it normal to have a delay before the rest of my pages are showing up on the results? And if so how long does it normally take for the rest of the site to appear!?
The site first appeared on 10th Sep, then is disappeared for a few days and now its back... but still only the main index page...
(i have text links to other pages from index page!)
Thanks for any info, im new to this and find your postings very valuable!
As you read back, you'll notice that mid-cyle adds can drift in and out; there's steady fluctuation all the time now. It's hard to know a specific for a site, it would depend on how many pages they got and when they got them. The best indicator is seeing what's happened with other people in similar circumstances. A lot depends on luck and timing.
