The website owner has installed an Alexa Certify Code on the pages of their site and chosen to show the metrics publicly.
There was a good amount of results when searching for local members, many had photos and filled out profiles.
Global traffic ranks of 100,000 are subject to large fluctuations and should be considered rough estimates.
If a site has Certified Metrics instead of estimated, that means its owner has installed code allowing us to directly measure their traffic.
The more traffic a site gets, the more data we have to calculate estimated metrics.
Estimates are more reliable the closer a site is to being ranked #1.
