This has been for two weeks, I'm starting worrying about it. http://www.vocaboly.com/ is not cached by Google if check with Google toolbar, but it's still in the SERPs(search "vocaboly"), if check the cache from there, Google still crawls the site every day and keeps indexing new pages. Should I ask Google about it?
i have found when a page is not in cache at google it helps to change just something on the page or reload the page but with todays date... have had pages not in cache before but logs were showing googlebot was getting a 304 page not changed message so did not re-download again hence changing the file date, or adding an extra space somewhere on the page has usually sorted it for me.
