Google update history discussion

Discussion for the Google Update History Chart:

I dont see no trend. I think GG just flicks a switch and it goes into update mode :)



 4:13 pm on Apr 11, 2002 (gmt 0)

Yes very sexy tables with the rotating coloring going on. I think its even worthy of printing. GoogleGuy I dont think anyone here would like it if you posted the schedule in advance. Teoma may use the schedule to their advantage by updating before Google does ;) winning a few more webmasters over.

Darn! My printer didnt print the alternating table cell colors, now I have to bust out the highlighters.

3 missing bits of data: days between updates, the week of month, and moon phase of update ;)

Google's future update list?!

You might as well sacrifice a chicken over your computer while standing on your head counting backwards from one million... underwater.

GoogleGuy, if you wanted to start making some real money you could sell that list to SEO pros and web masters.

The Internet mafia..........


 5:13 pm on Apr 11, 2002 (gmt 0)

Do you mind if we send you the advance schedule?

For god sake, let him be! IF HE DON'T WANT IT HE DOESN'T WANT IT UNDERSTAND!!!

But you can send me a copy, just in case you have a servercrash ;)

>Sunday - 6 updates

You guys shouldn't work on Sunday, you should go to church ;)

>and moon phase of update

Everything you could ever want to know about the moon!


Trying a gentle nudge back in the direction of the original topic ;)


 5:35 pm on Apr 11, 2002 (gmt 0)

Great table!:-) So Brett, how often are you going to update this table?


 6:27 pm on Apr 11, 2002 (gmt 0)

Googleguy if you joined Plex later from the dates of the update of the schedule that Bret supplied, it is good to have a look..... :) just for history info


 10:33 pm on Apr 11, 2002 (gmt 0)

Add the days in between! That would help a lot!

>> and moon phase of update

I don't know that it makes a difference to when google updates but it makes a difference to where my site is in the index. (read earlier the update the higher my pages).


 1:41 pm on Apr 12, 2002 (gmt 0)

Do those date & times indicate the first signs of the update or when it seems to have "settled in"?

The most recent update seems to have taken the longest to stabilize of those in recent memory (i.e. first signs of changes on Sat. night, inconsistent results still showing up yesterday afternoon).


 2:10 pm on Apr 12, 2002 (gmt 0)

Those are the first time we noticed an update had occured. The www2/www3 phenom didn't start until early last year really. Not very many people like us watched for updates in 98-2000 because their was no clear pattern. The pattern didn't settle in until Googles hardware/software/data centers were flushed out in late 2000. I can still remember back to the fall of 98 when Google updated for the first time from 25m pages to 75m pages. Back then, we were still thinking it was going to be a edu search site only. There were alot of updates last year that took 4-5 days to settle down.

>So Brett, how often are you going to update this table?

With every update of course.


 4:24 pm on May 24, 2002 (gmt 0)

Again I printed out the tables :) Love the updates. That is what makes for a good site. (:


 1:15 am on May 25, 2002 (gmt 0)

Two things I found interesting - the average period between updates is closer to 31 days, not 28, and March was skipped in 2001 and quite late in 2002. Perhaps Brett takes holidays at this time of year (spring skiing??) and misses the update, or Googleplex takes a break. Brett? Googleguy?


 4:41 am on May 25, 2002 (gmt 0)

Found the long lost March 2001 thread. I don't know why that one disappeared from the system, but I was able to resurrect it from backups. It is now included in the tables.

March this year was just the way it is shown - not until April 6th. No explanation was ever given.


 10:11 am on May 25, 2002 (gmt 0)

Very nice, Brett!
I think you made a mistake with the links to the corresponding threads for October & November 2001 (same link).
It'd be great if you could add the number of days between two updates :-)


 1:52 pm on May 25, 2002 (gmt 0)

Brett, you are one amazing guy! When you write your autobiography (Brett Tabke: How I conquered the Search Engine World Using Gradients and Tables), I'd like a signed copy please.

Very nice job!


 2:52 pm on May 25, 2002 (gmt 0)

hehe. Everyone loves a good table.


 4:51 pm on Jul 23, 2002 (gmt 0)

Thanks oLeon. I have updated the display.


 1:10 pm on Aug 21, 2002 (gmt 0)

Brett, isn't it August 21, 2002? ;)


 8:46 am on Aug 22, 2002 (gmt 0)

Thanks - didn't get that col updated - all fixed up.

I also added moon data. It was programmed.


&moon("7","21","2002"); #month -1, day, year.

sub moon {

$src = "---/moon/"; #url to YOUR moon gfx directory
$base = 679268563.19; # "average" new moon on 21:42:43 7/11/91
$period = 2551443; # 29 days 12 hours 44.05 minutes synodical period
use Time::Local;

print "Content-Type: text/html\n\n";
($month,$day,$year) =@_;
$t = &timelocal($sec,$min,$hour,$day,$month,$year);

$phase = ($t - $base) / $period;
$phase -= int($phase);
$phase *= 32;
$phase = int($phase + 0.5);
$phase = 0 if ($phase > 31);
$file = $src . "moon_";
$file = $file . "0" if ($phase < 10);
$url = $file . $phase. ".gif";
print qq<IMG SRC="http://$url" height="32" width="32" border="0" title="moon phase">;


 8:55 am on Aug 22, 2002 (gmt 0)

Love the moon :)


 9:00 am on Aug 22, 2002 (gmt 0)

Can you also post the end date and time for each update ?


 9:24 am on Aug 22, 2002 (gmt 0)

nice table Brett,

GG, don't tease. If your going to hand over the schedule just do it.


 10:04 am on Aug 22, 2002 (gmt 0)

Brett - would it be possible to add a spider date to the table?
On one of my sites (not the profile one) I show the date using SSI code. Therefore, if I check Google's cache I can see when the site was spidered for inclusion in the update (e.g. the cache for www3 shows my site with a date of 6th August, meaning that this was when the spider passed by for the current update)

I believe we'd all like to have an idea of when the spider is doing it's major crawl for the updates.

Don't know if this is possible or not - maybe if you just took the webmasterworld.com site as an example.


 10:06 am on Aug 22, 2002 (gmt 0)

adding a spidering date field, would be near on impossible. Reason being that different sitesget spidered at different times and frequencies, dependant on traffic, content change, size, etc.
