Frequency & Percentage of Content Change to get Google to Cache Every Day?

[bozzie311]

What is the frequency at which your homepage (for example) would have to update and what percentage of the page's content would need to be updated to get cached every day?

What are your opinions on other factors.

Are you talking about caching or crawling?  Caching is a resource intensive process, and most sites are not cached daily, not even ones that are updated daily (try searching for your favorite news site).

Ideally caching. I can see how many pages get crawled each day in webmaster tools but that doesn't mean that page gets cached and reflected in the algo?

[TakeshiYoung]

The cache date that you see in the search results does not necessarily correspond with the last time your site was indexed.  Your site may have been re-indexed with your new content today, but the cache might still show your page from a week ago.

The best way to improve crawling and indexing is to improve your PageRank.  The higher your PageRank, the more resources Google will be willing to spend on your site.
