|Meaning of Google's Cache Date||gardener||6/25/09 5:47 AM|
I just looked at Google's cached page of a search result, and at the top it said
'this is a snapshot of the page as it appeared on Apr. 28, 2009"
Does this mean that Google's robot hasn't crawled this particular page since Apr. 28? If so, isn't this an unusually long time for Google to wait before crawling it again, since it has been almost two months? Could someone please give me more information about this matter?

You may think that the page hasn't change, but all my pages are recached on a regular basis and they do not change.
So, have you made changes to the page, cause looks like google doesn't like it anymore.

The Cache date is the last time that Google Crawled and took a copy.
If you look through your logs - you may see the bot hit that page after that date.
(At least, that seems to be the case?)
Remember there is often a gap between being crawled and stuff showing in the SERPs.
(so you may be seeing the 28th April .... but G may have visited on the 12th June.... and it simply hasn't pushed it to the SERPs yet!)
The time between crawls really does vary.
Depends on things like the age/trust/popularity of a site, plus the internal link structure, popularity of a given page and those it links to, the change frequency for a page/site etc. etc. etc.
Some pages may go for quite some time without being crawled.

Quickest way to find out, change your meta desciption, if it doesn't update in a keyword search then you could have issues. We find this a valuable way of checking there isn't something wrong with a page not being indexed.

Thanks for the replies. Actually, this page isn't part of my site, so I can't check the logs or anything. I was just wondering why it's been almost two months since the cache date. Does it mean that Google noticed that the page hasn't changed in a long time, so doesn't crawl it very often? Or could there be some other reason?

Please stop beating about the bush! Just tell us the URL of the page in question otherwise we are groping in the dark!

It is difficult to know exactly what the cached date you see means.
You are looking at only one Google datacenter, other people might see the cache presented
to them from another Google datacenter,
the site might have geo-targetting settings, that complicates things even further.
The Google algorithm and its implementation are very complex,
there are many layers and datacenters.
Usually when the date of the cached copy is a few months old, there is a problem with that URL,
either there are no (or very few) crawlable links to it,
or there is duplicate content in other URLs,
or there might have been some server errors that prevented Googlebot in updating the cache,
As Robbo wrote, without the URL (preferably the URL of the cache you are seeing),
we are just going in circles with this discussion.

Okay, here is the URL of Google's cache of the page, if anyone wants to look at it. Thank you

I have a question. I am trying to figure out how often Google crawls my site because it varies widely. I've been tracking the cache date. Yesterday my cache said it was 10/30, but today it says 10/21. Why does it revert backwards like that?

Christian - you really need to start a new thread.
|Re: Meaning of Google's Cache Date||christiannegordon||11/3/09 11:50 AM|
Thanks Ashley - I'll do that now. I didn't want to get in trouble for starting a thread that was already being discussed as I'm new here :-)
