I'm trying to figure out how Google is working since i have seen some weird things lately so excuse if I am just ranting and repeating other posts here Whenever Google finds your site they take a copy of you page and store it away in one of their cache servers. Then, whenever they think they should crawl the site, they use this cached copy instead of getting the current page even if the current page is newer and have more or changed information. They also use this cached copy to display result from in their SERP's and use it for algos and probably a lot more stuff. If you have adsense then they probably use it to match up advertisers to that page and when you load a page with adsense in the broswer it doesn't really "sense" the page at all but the code is matched with the page through their script. The problems I have seen lately is when they roll back to cached pages from August last year instead of using a newer cache then a lot of pages are corrupt because of changed links, paths and other stuff we have been working on for a year and the we go supplemental since everything they have are screwed. I guess they are hoping that in August last year is when they can start over with their algo to get rid of spamsites (maybe that's when they actually started showing up but none saw them until now?).... It's like when we have a restore point that we think are good because we had a virus we need to get rid of and now we loose a lot of software we have installed and now we/they have to start all over and crawl sites again and what do they do? Use the cached pages and goes from there........ Well, like I said.. maybe just ranting and writing it down to try to understand a little bit of what's happening here....
Well, I'm not involved with AdSense, so I'm not sure I'm correct in what I'm saying. However, I do have some difficulty in thinking that Google will refer to a cache that's several months old. The only reason I can think of for their doing so is that the site owner hasn't changed anything in all the intervening time period. Otherwise, I'm quite sure that they'll work with the latest version of a site, which ought, I also imagine, to ensure that there'll be a corresponding difference in the AdSense appearances. Duncan
One of the reasons I am thinking that they are using old cache pages is that in some of then I have some links to pages I do not use anymore, pages that gets crawled right now. I think, that they take this old page, instead of hitting the sites again to get a fresh page, grabs the links on that page to get another page to crawl. What they don't do, is to place this new page in the cache in exchange for the old one like MSN does. If you check MSN then their cache is usually just a few days old but if I look at a lot of pages in Google, they are cached in August last year and I am sure there are newer cached pages in their database but for some reason they have reverted back to old chached pages. I have seen other posts here saying the same.. maybe not from August like in my case but cached pages from last year....
I had a look at your site and you have 2 pages in google. One is a supplemental page and the cache is from Jun 25, 2005 14:41:39 GMT. Don't know if you haven't changed it since then but it seems pretty old.
