Hi,
I have recently noticed that after I created a new adgroup on Google adwords, the landing page was updated in SERP almost straight away.
I then tested it with a couple of other landing pages which had not been visited by Google for ages, and they got updated in the SERP within a couple of days!
It looks like adding a link into adwords ensure that their spider goes and visit the page, and update its content in the SERP.
I have done some research about this since, and could not find any information about it.
Am I on something, or is it some kind of common knowledge?
