Certified Site Metrics are metrics that are directly-measured from the website instead of estimated.
Note that the percentages can add up to more than 100% because a visitor can visit multiple subdomains during the month. The reported load time for a website is the median time it takes to load pages from that site in a real users' web browsers.
Other Sites Owned These are other sites with the same registered owner as this site.
Sites with Similar Names There are domain names that are similar to this site.
We identify these patterns by looking at the activity of millions of web users throughout the world, and using data normalization to correct for any biases.
The more traffic a site gets, the more data we have to calculate estimated metrics.
