Web traffic measurement agency Nielsen/NetRatings will reportedly scrap the "page views" metric in response to the growing challenge posed by dynamic websites.
Ajax websites and web-based videos mean content can be loaded with no web page reloading, so the firm will begin instead reporting the length of time users spend at audited sites.
Steve Rubel at Micro Persuasion has an interesting article where he speculates what will replace the page view metric, which he believes will be dead by 2010.
Page view or page impression figures are easy to manipulate and don’t give a true measure of a site’s popularity. For instance, merely splitting content over several pages can falsely inflate a site’s figures.
