I didn't understand the values of the chart -page-views (google stats).
For example, for google, what mean these values ?
Millions, billions of visits?
In my case, I want to know how many visits the site have per day (average)
Alexa measures traffic in relative terms, not absolutes. The values mean Google.com's page views accounted for 4.834% of total page views of Google.com. The -0.6% indicates that there was a drop of 0.6% of page views in comparison to the previous day.
