Certified Site Metrics are metrics that are directly-measured from the website instead of estimated.
Seriously, whether it’s the constant single shade of gray or the fact that we’re just too laid-back, there’s no place tougher to find the one…
Not all websites implement our on-site analytics and publish the results.
For these sites, we show estimated metrics based on traffic patterns across the web as a whole.
For other sites, we display the estimated number of unique visitors from up to 6 countries, when sufficient data is available (Advanced plans only).
Audience Geography The audience geography data describes where visitors to this site over the past month are located, and how the site is ranked in popular countries. Engagement metrics help you understand how interested a site's visitors are with the site's content.
