Google Does Not Update Cache On Each Crawl

googlebotProbably obvious to many SEOs and webmasters out there, Google does not update the cache of your web page every time they crawl your web page.

As you know, Google spiders, aka GoogleBot, will crawl sites like this hundreds of times per day. Google obviously won't update the cache result of this site hundreds of times per day. But on more static, less dynamic web sites, Google will crawl less often, sometimes once or less per day. You still can't expect Google to update the cache of your site on each crawl.

Google's JohnMu clarified this in a Google Webmaster Help thread saying:

In general, we do not always update the cached page every time that we crawl a page. Especially when the page does not significantly change, we may opt to just keeping the old date on it.

Technically, Google likely can update the cache more often but it is a matter of resources and utility. Personally the reason I use the cache, in most cases, is to see older content that might have been deleted. I personally like a few day delay in the Google Cache. Of course, most webmasters and SEOs want a more real time update of the Cache to better test their changes and such.

its quite obvious actually. Google won't update old cache or static cache very often. Is there any way to tell Google to update cache though?

Not that I know of. You can tell Google not to show a cache link by using the noarchive meta tag.

Google polled SEOs some years ago on how useful it would be to update the cache more frequently. Unfortunately, most respondents appear to have NOT understood the importance of seeing Google's cache reflect changes in its index. The "don't update so often" crowd won out. The present behavior is not very helpful in search optimization but it seems to be carved in stone now.

Yes. thats something I also experienced with one of my website. I updated the canonical issue for one of my website from Google webmaster tools preferred domain settings but its not updated in the Google search yet. Believe it has something to do with more and more websites coming up and Google has not enough databases.

Google has been rebuilding its index over the holiday period, so mostly what we are seeing is the index up to 16th december with only a small amount of updates since compared to usual. The serps you see now will be totally replaced by the new rebuilt index. Google is finally fighting back against the onslaught of increasing scraper spam sites, we should see a big improvement :)

Thanks for this information as i had been wondering why google bots were visiting the site but cache dates were not changing. I assume that if content is updated more frequently then this could result in cache being updated more often?

people have generally missed what Mat Cutts, (and religiously chanted as mantra by every Google employee since) meant when he dropped the biggest hint of all "fresh unique content". Here's more of a hint for the slow to grasp, measure your keyword stats in webmaster tools against your site content. Now bearing that in mind, Google need only update their cache yet once a month when they serve up a different set of serp's

Is there anyway I can speed up this process? My cache was last updated in 1.5 months ago. However, I have done some changes on the website.

If Google did not cache the page that means Google did not read the content in it, so how will it give search ranking on the keywords contain on the web page.
