People Count
People Counts are also known as unique visitors - they only count a person once no matter how many times they visit a site in a given month. People Counts are typically used to determine how popular a site is.
Recommendation: To best understand the popularity of a site, you should consider additional metrics beyond People Counts.
For instance, Site X could drive up its People Count by buying a lot of advertising across the Internet. However, many of these people may leave the site immediately. Use Engagement metrics to understand how much time people spend on a site and how many pages they look at on average during each visit to more fully understand the site’s popularity.
this information is from multiple data sources, including ISP, Panel & Toolbar to estimate U.S. traffic.
