Even some of web sites dropped to PR0 I suggest guys to watch site's cache time by " cache: your site " If the the cache time is still changed very often then I think G still like your site very much . If your site get G cache time is one month ago then it might a danger message perhaps the site has duplicate, link problems or others. May the thought helps.
Interesting idea. Not sure if it is true but it might show what google thinks about site in terms of being updated often.
Imo the crawl rate is connected to the size of your site and trustfull links linking to your site , pr effects it less than these factors.
Cache date changing often generally means that new content / changes are found on the page/site. I have pages with older cache dates because they never change and others that are crawled about every 2 days due to fresh content.
i only know one think about the google cache. more backlinks will bring you more cache. google will love you with more backlinks from trusted web sites
one of my sites was suddenly dropped from pr3 to pr0 but i still have v.good SERP's and my homepage cache is updated about once a week so i guess G still likes it
I think your right with this point of cache time.. as ever see that g cache some sites in just 2-3 hours or may be in few minutes.. sometimes i also realize it.. that these site SERPs is good than other one.. Dilpreet
I recently got a interesting cache time.... Day 1, then Day 4, then Day 5, 6, 7, 8, then Day 13, then Day 15, then Day 16, 17, 18.................... Also if webmaster tools shows Day 1, then Cache shows Day 5........
My blog indexed get cache between 2-3 days. But the inner pages doesn't cache often. Sometimes it takes 2 weeks to cache again.
Agree, sites which I update frequently get cached every 1-2 days. Other, which i update once a week or 10 days, get cached once a week or more rarely.
Every 1-2 days? Man, my site is an article directory and gets many articles in a day... And still showing November 24th....
