Google's John Mueller said in a Google+ hangout this morning that there isn't a direct relationship between a web page getting crawled more frequently and it ranking higher in the search results.
He said this at the 1:34 mark. into the video saying, "So it is not true, that if a page isn’t crawled regularly that it won’t show up in rankings at all."
The question was:
Is it true that if a page hasn't been crawled recently it wont rank well or be given less authority? Also Is there any advantage is re-submitting our sitemap weekly or more often?
The answer John gave:
So it is not true, that if a page isn’t crawled regularly that it won’t show up in rankings at all.In general we try to do our crawling based on when we think this page might be changing, how often it will be changing. So if we think that something stays the same for longer periods of time, we might not crawl it for a couple of months. That is completely fine, we can still show it in search.
So that is not something I’d say is a direct relationship.
Often times, it is kind of a relationship that, when we think something is important we tend to crawl it more frequently and that might be more visible in search. But it is not really the case that we can say from the amount of crawling, it is how important it is and shows up in search.
And similarly, it doesn’t make sense to resubmit things...
