TechLeads scans public websites and detects Amazon Advertising from signals in the page HTML, scripts, cookies, HTTP headers and DNS records. Market share is Amazon Advertising's website count divided by the website counts of all Advertising technologies we track; a site using two Advertising tools counts for both. Counts were last refreshed on October 8, 2026 and update daily.
