Composition

This list aggregates the ranks from the lists provided by Alexa, Umbrella, Majestic, and Farsight from 02 August 2022 to 31 August 2022 (30 days). Read more on the methods used by each of these lists and our aggregate list to understand each list's properties and potential shortcomings.

These lists were combined using the Dowdall rule (the first domain gets 1 point, the second 1/2 points, ..., the last 1/N points and unranked domains 0 points). This method roughly reflects the observation of Zipf's law and the ''long-tail effect'' in the distribution of website popularity.

For each list, all domains were used.

The following filters were applied to the domains:

• Only pay-level domains were retained.

Of the aggregated and filtered list, all domains were used.

The list was first generated on 31 August 2022.
