Can Google move up my ranking without caching it ?

Is it possible that my site was last cached in Google on  9 Oct (it was ranking 23 that time) and today on 29th oct its ranking position 3 for a kw though still showing cached on 9 oct.

Its not cached since 9 oct, does that mean its not crawled since then? How can Google move up my ranking without caching it ?

With Google rankings changing as much as they do nowadays (multiple times throughout the day), I don't think the cache needs to be refreshed for rankings to change - it would be inefficient.

There could be a number of factors in play, such as competitors losing rankings, or Google temporarily testing your site in the top rankings to see how it performs, or new links/social shares for your page that didn't initiate another crawl of the page. I wouldn't worry too much about the cache date in regards to rankings.

Thanks Kane, yeah that make sense.
