Certified Site Metrics are metrics that are directly-measured from the website instead of estimated.
The website owner has installed an Alexa Certify Code on the pages of their site and chosen to show the metrics publicly.
Estimates are more reliable the closer a site is to being ranked #1.
Global traffic ranks of 100,000+ are subject to large fluctuations and should be considered rough estimates.
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.
