How these numbers are calculated

TechLeads scans public websites and detects FullStory from signals in the page HTML, scripts, cookies, HTTP headers and DNS records. Market share is FullStory'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 8, 2026 and update daily.
