How do we determine from which country a user visited a website?
Similarweb uses four different types of data sources that allow us to look beyond IP addresses to understand where a user is accessing a website - including, but not limited to, networks, device codes, and more. These sources, coupled with our proprietary data synthesis and modeling, allow us to categorize traffic by the country where a site was accessed.
How do VPNs affect which country we attribute a website visit to?
We attribute a visit to the country from which we detected their first visit of the day. For example, if someone from country A logs onto their computer and visits a website, and then 5 minutes later connects to their VPN (country B) and visits more websites throughout the day, all website visits for the entire day will be attributed to country A.
What is included in the worldwide country filter?
Worldwide data includes both data from the country filters that we manage and display on the platform, as well as data from a variety of other countries.
The data collected from countries that do not have an independent country filter is not at the scale where we are able to display them independently, however, because of Similarweb's global methodology, we still have coverage and data in those geos. This data is available when analyzing data with the worldwide country filter.
