In order to account for this fake traffic, webmasters must tap into a new Page Visibility API [code.google.com] that Google has submitted to the W3C as a standard.
This really doesn't make any sense at all.
The Visibility API is code that runs client side, AFTER the page has already been served! By that time, it's too late to do anything about it. Yes, can do things like minimize the effect of pages that make AJAX requests to the server, but it really doesn't address the issue of skewed traffic numbers from pages that are pre-rendered.
