Mixed in here are search engines and metasearch engines. Metasearch engines like DDG, Metager, and Searx are not actual search engines but rather sites that query other engines. I would rather see only actual search engines for comparison. I would like to see some non western (search engines based in non NATO aligned) countries included such as Yandex.

Data collection always happens. How does the engine know what to return if you did not send it a query(data)? Sometimes results are personalized/manipulated. Anonymity reduces impact of both.

There is something that is irrefutable that sadly google has the best algorithm and most crawled information. So it has by far the best results using it correctly with parameters. Sometimes I fall to use it but i take my precautions like in a separate container using Firefox Multi account containers and some other stuff

Do you have this in ods, csv or at least xlsx?

What is Metager?

Excite still exists?

Why should startpage be censored?

Source? How is possible that Startpage is listed as Censorship: Extreme?
