Alexa Ranking For MySpace (per million???)?

Hello,

I'm confused here... if you look at http://www.alexa.com/data/details/traffi...

and you click under PAGE VIEWS, the graph shows, approximately, 20,000 on the X-axis and in bracket at the top it says "Daily Pageviews (per million)". Does this mean MySpace gets 20,000 x 1,000,000 = 20,000,000,000 or 20 billion pageviews DAILY?

If i'm wrong, how is it calculated or interpreted (i.e. Daily Pageviews (per million)?) Thanks.

Alexa Ranking For MySpace (per million???)?

Page views per million indicates what fraction of all the page views by toolbar users go to a particular site. For example, if caribisls.com has 70,000 page views per million, this means that 7% of all page views go to caribisls.com. If you summed the fractional page views over all sites, you would get 100% (this is not true of reach, since each user can of course visit more than one site).
