I got the following explanation from Similarweb which I personally don't completely understand, but Alexa uses similar techniques for estimating:

We take a very unique, multidimensional approach to how we collect our data. We use data extracted from four main sources.
The first one is our global panel, which is made up of hundreds of millions of global devices in 190+ countries. The panel allows us to analyze anonymous consumer behavior on a massive scale, making it the largest and most diverse panel in the industry.

Global ISP Data is then used to supplement our insights about digital behavior. We partner with Internet Service Providers from around the world that provide anonymous data, almost identical in structure as our panel data.

Thirdly, we implement an automated technique of capturing and indexing public data from over a billion websites and app pages every month.
Lastly, we leverage a growing dataset of hundreds of thousands of websites and apps that share their directly measured analytics with us.
We then transform all of the data sources into intelligent estimations across all sites and apps for all geographies.
