Google updating website
If you’ve recently added or made changes to a page on your site, you can ask Google to (re)index it using the Fetch as Google tool.
The "Request indexing" feature on Fetch as Google is a convenience method for easily requesting indexing for a few URLs; if you have a large number of URLs to submit, it is easier to submit a sitemap. Both methods are about the same in terms of response times.
From my experience, factors that contribute to quicker crawling and indexing revolve around: Throughout my career, I have had sites rank changes in as little as 30 seconds and as long as a few weeks.
So, it was with considerable trepidation that I switched to the new Google Sites this semester...
But typically, you have to wait around for the Googlebot to crawl your website and add it (or your newest content) to the Google index.
So the question is: how do you ensure this happens as quickly as possible?
but now that the students' websites are up and running for the semester, I can say that I am very happy about it!
The new Google Sites approach to web design is not something that would appeal to me personally, but it sure does appeal to my students.
