Alexa, a web information and tracking company, keeps a running tally of the top 500 sites on the web by calculating a domain's daily visitors and pageviews over the past three months.
Using their most current rankings, we've compiled a list of the 19 most popular websites and included important metrics also tracked by Alexa, such as incoming links and global reach.
