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