Ranking Improvements
We've improved our ranking algorithm by adding traffic estimates. Before this update, we calculated rank for domains in our database based on harmonic centrality and page rank from the Common Crawl dataset. Centrality and page rank are based on the links between domains. They are a good indication of the connectedness of a domain but are not the best indicator of a domain's popularity. As a result, some of the top domains under the old algorithm were a bit of a headscratcher.
