Does anyone know the normally expected time relationship between page changes appearing in the Google Cache and SERPS Positions resulting from those changes.

Thanks in advance.

It varies by query, region, Website, etc.

Mmmmm thanks Michael
I'm predominantly interested in Uk results. However from what you say, that is far from enough info for you to be definitive.
Would you be prepared to have a stab at a "likely" window sort of from/to in between sort of guestimation.

You have to clock each Website's cache update frequency on a page-by-page basis. I have only done this for relatively small sites.

You also have to know what the competitor sites' update-to-cache lag times are. What you're asking about is NOT a simple calculation. I wrote about these kinds of computations on SEO Theory years ago. You can read the article ("New SEO definitions to ponder…") through these Bing search results.

So, having explained all that, if you still want me to take a stab at it -- understanding that is just pulling numbers out of thin air; based on what I see in (predominantly) US search results, my guess is that it should work something like this:

ON EDIT: This illustrative example assumes no other sites in the query are making changes

FOR NEW CONTENT
High PR + Daily/Hourly Publication = Immediate update

High PR + Weekly Publication = Daily update

Low PR + Daily/Hourly Publication = Immediate-to-daily update

Low PR + Weekly Publication = 1-3 days update

FOR UPDATED EXISTING CONTENT, linked from home/root page

High PR + Daily/Hour Publication = 1-2 days update

High PR + Weekly Publication = 3-5 days update

Low PR + Daily/Hourly Publication = 1-3 days update

Low PR + Weekly Publication = 4-10 days update

FOR UPDATED EXISTING CONTENT, *NOT* linked from home/root page

Add 7-10 days

If you publish content on a monthly or more seldom basis, add another 7-10 days.

THESE ARE JUST MADE UP NUMBERS.

It varies from site-to-site, from query-to-query, from region-to-region.

I don't know of any way to make a reasonable prediction without having the Crawl-to-Cache times and other relevant data for the pages and queries concerned.
