Google's rolling update

Every 3 days

[coconutz]

We added a new page in mid-May that hasn't been too difficult to get links to and the number of results returned when searching for the unique title has increased usually every third day over the past month or so.

Others have mentioned that googlebot seems to be deep crawling every 10 days, but we're seeing behaviour unlike freshbot approximately every third day. The SERPs appear to reflect a minor update about as often. The largest increase in results was yesterday.

Anyone else observing anything similar?

I'm seeing a constant cycle of one week, freshtags for about 2-3 days(eg.7/6 then 7/9), then (7/13) reverting back to an old page (1 month old). The old page is listed for about a week, then freshtags appear agin.

The page is toolbar PR3 but should be a 5/6 -internal pages are 4s, dmoz listed, # 4 in the serps for a one word term, #3 when freshtags are present.

I see the googlebot often, but the period is hard to nail down, and seems to vary greatly with PR (or what I think the current PR of a given page should be since it is no longer available with any certainty). It is also increasing for this particular site.

Here are my googlebot counts by day. I suspect that a careful analysis may be able to pul out some harmonics based on the PR of some of the pages with higher PR pages having a higher frequency.

If only they would update the damn backlinks.

I really feel that Google have updated the links in theory but havent displayed them yet.I have a site thats a pr7 because of a link from a pr8 that hasn't been there for at least 6 wks.I just had to add a page and I automatically went to the top of the serps.Last week I got dropped just as I would expect from google discounting my pr8 link even though it is still showing it.
Another site has climbed just as if they have counted a link that I have recently acquired.

exactly the same for me Cabbie. Looking forward to it permanently acknowleding my new incoming links.

Yep, it seems to be that Google knows about backlinks (for some sites at least) but doesn't choose to report them, and not because they are below PR4.

I have several sites that are placed according to backlinks and anchor text I know exists, but Google denies any knowledge when questioned.

Having said that I also have some sites that are still suffering with the similar backlinks that Google hasn't yet found and of course still denies.

I'll live with the lack of good reporting features, i.e. link: and toolbar PR as long as the SERP's reflect reality.

Exactly the same pattern for a couple of our sites that are about 2 months old.

On closer inspection of my own numbers that I posted, it does seem like a one week deeper crawl cycle with the deeper crawl on Sundays (makes sense - slowest day of the internet). I believe the freshdates are down again today, and I also remember that one sign of the old dance was that fresh dates dissapeared.

There are a few spikes in that time, but I suspect that that is from addition of links in (I don't remember the dates).

The googlebot is gettin' busy on this site as I post.

I still don't see the three day period, except that there is an apparent day of rest on Mondays, where numbers may be crunching.

Hmm...maybe not every sunday, here is another site's googlebot visits:

We had pages updated last night. They are new pages, put up on Friday the 25th, spidered on Sunday/Monday, in the serps today (Tuesday th 29th).

Hopefully these will stick - this seems to be the pattern, and if so, we were 'updated' again on Monday/Tuesday (28th-29th).

*really loving this new Google. So much easier to see the results of new content!
