comScore customers by country
Based on country-code domains (such as .de or .co.uk); websites on .com and other generic domains are not assigned a country.
TechLeads scans public websites and detects comScore from signals in the page HTML, scripts, cookies, HTTP headers and DNS records. Market share is comScore's website count divided by the website counts of all Analytics technologies we track; a site using two Analytics tools counts for both. Counts were last refreshed on October 14, 2026 and update daily.
