- [Source website](https://tranco-list.eu/) - [Publication](https://tranco-list.eu/assets/tranco-ndss19.pdf) ### Description of the list > Researchers in web security or Internet measurements often use rankings of popular websites. However, [in our paper](https://tranco-list.eu/assets/tranco-ndss19.pdf) we showed that these rankings disagree on which domains are most popular, can change significantly on a daily basis and can be manipulated (by malicious actors). > > As the research community still benefits from regularly updated lists of popular domains, we provide **Tranco**, a new ranking that improves upon the shortcomings of current lists. We also emphasize the reproducibility of these rankings and the studies using them by providing permanent citable references. > > The Chrome User Experience Report and Cloudflare Radar rankings have been integrated into the default Tranco list, starting from the daily updated list of August 1, 2023. The Alexa ranking has been removed from the default Tranco list, as it is no longer available. --- #### Related #data_source
