TechLeads scans public websites and detects AdOpt from signals in the page HTML, scripts, cookies, HTTP headers and DNS records. Market share is AdOpt's website count divided by the website counts of all Privacy Compliance technologies we track; a site using two Privacy Compliance tools counts for both. Counts were last refreshed on October 12, 2026 and update daily.
