How often does Google re-index websites?

Jim Reed from Vancouver, Washington asked us "How often does Google re-index a website?"

You might also be wondering how long it takes Google to recognize changes on a website. We'll answer that question and give some general tips in this video.

A nice video John but I don't think it really addresses how long the full process takes. You mention crawling but you don't mention how long it takes to re-index and push out the changes to the local data centre. If I'm in position 10 and I add some really relevant information that makes me the most relevant website on the internet, how many days or weeks would it be before I appear at the top of the listings: That is how long will it take to crawl, index and push-out the changes?

Hey John, what are the best practices for links in sponsored articles? Do we need to insert nofollow? Is there any value from such links or that would make the recepient penalized?

I have found a website guilty of securing PAID ad links in the form of image ads running into the millions of backlinks. They have been reported to Google for webspam AND paid links, but no action taken. Why are they not penalized?

What problem can a website have when they publish the same content on their website and on many other ADVERTISING websites "like jobs offers"?

And is there a way to fix it without writing a new content?
